4 General he measuring instrument Multi-Handy 2045 made by comany HYDROECHNIK GmbH, Limburg is an efficient hand held measuring instrument for the measurement of ressure, ressure eaks, ressure differential, volume flow rate, rev. seed and temerature. he instrument disoses of an internal memory ( measuring values) for the storage of the measured hysical variables. his measuring data is directly transferred to the PC via a serial interface. A rinter can be connected to the measuring instrument via an interface converter and can rint out the measuring data either as a table or a grahic. Rechargeable batteries make the Multi-Handy 2045 indeendent from a regular source of current. For recharging the batteries an external lug-in ower suly unit is available. he Multi-Handy 2045 disoses of two measuring inuts for the connection of sensors with a standardised, analogue outut signal of 0 to 20 ma or 4 to 20 ma. A direct measurement of frequency can t be realised with this instrument. However, with corresonding frequency/current converters (F/DC-converters), it is ossible to convert the frequency signals into standardised 4 to 20 ma signals, which can be evaluated by the measuring instrument. In doing so it is ossible to measure RPM and volume flow rate.

5 Instructions for charging the batteries Before each oeration of the measuring instrument, you should make sure that the nickel-cadmium batteries are fully charged. he use of a HYDROECHNIK lug-in ower suly unit (rimary 230 VAC, secondary 24 VDC) ensures a continuous charging of the batteries. Please take into consideration that the batteries are only slightly charged when leaving the manufacturer. We recommend connecting the lug-in ower suly unit to the measuring instrument for at least arox. 14 to 16 hours rior to initial use. he measuring instrument is able to measure when sulied by any other ower unit or a car battery but in such cases the recharging of the batteries can not be ensured, as a stabilised ower source of 24 to 30 VDC is needed for this. If a battery is discharged it should be recharged for 16 hours, the instrument being switched off. he service life of nickel-cadmium batteries can be very long, deending greatly on their resective working conditions. It should be avoided that the batteries are totally discharged, ermanently recharged or immediately recharged after each use. Discharging them below 50 % and recharging them afterwards has got a ositive imact on the life san of nickel-cadmium batteries. Due to the so-invoked memory-effect that reduces cell caacity, recharging nickel-cadmium batteries after very short time of use cannot be recommended. If the battery is reeatedly discharged to a minor degree but immediately re-charged, the cell s caacity will soon be reduced. If that is done over a longer eriod of time the battery can suffer ermanent damage. here is a chance, however, to regenerate said damage by a number of discharging and recharging cycles, i.e. by using the instrument for a longer eriod and then recharging the battery. Should the batteries not be charged sufficiently, a warning will be dislayed Charge batteries. In such cases a minimum of 16 hours recharging time is urgently required. -5-

Strong chemical solvents may not be used, as they attack the housing. Make a contribution to the environmental rotection! Recycling for environment s sake! Used batteries do not belong into the household refuse. Please throw your batteries into a secial recetacle for disosal of refuse and sewage. -6-

7 1. Oeration Multi-Handy 2045 wo measurable variables can be shown at the same time on the 2-line LCD-dislay. he first line is reserved for the ressure channel 1. In the second line either ressure 2,, ressure differential d, temerature, volume flow rate Q or rev. seed n can be shown. On the keyboard you will find two keys, which can only be ressed in connection with another key. hese are the keys and. In doing so you have to take into consideration that the eriod between ressing the first and the second key must not be longer than three seconds. After three seconds the key ressed first will be ignored. All inuts need to be finished with /. 1.1 Dislay examles initialisation version 1.xx Deending on the number and the tye of variables, the values are dislayed in different sizes. In the following you will find several examles about the dislayossibilities of your instrument. After having switched on the instrument, this menu will aear for arox. three seconds After, that, the measuring value dislay will aear automatically. By ressing for examle key 1 corresonding value as a single, enlarged number. the dislay shows the If the measuring value of 2 shall be shown in the same size, you only have to ress key 2 and the corresonding ressure measuring value of 2 is dislayed Another stroke of key 2 shows the usual dislay with two lines, indicating the measuring values of 1 and

After a stroke of key ( the measuring value: 1-2 ) = 1-2 ( = 32.1) is dislayed in the second line As already described on age 7, an enlargement of the dislay can be achieved by ressing key 1 and key. ( 1-2 ) d N [rm] he measurement of RPM N instead of 2 in the second line of the dislay can be invoked with a stroke of key Q. n 1 Q [ C] he measurement of volume flow rate Q instead of 2 in the second line of the dislay can be invoked with a stroke of key Q. n 1 [ C] he measurement of temerature instead of 2 in the second line of the dislay can be invoked with a stroke of key Q. n We have refused to give further examles to avoid confusion. -8-

9 1.2 Initialisation It can haen, that the information in digital storage systems is distorted, due to very heavy electromagnetic interference, not within the values of the EN and EN 50082, that can occur in industrial lants. his shows itself in an amount of data that must be considered unrealistic or the instrument doesn t react on a keystroke any more. For this case you have the ossibility to set all data back to a given state by a so-called re-initialisation. However then, all data like calibration value, language, units of measurement, outut signal of the ressure- and temerature sensors and all arameters, entered reviously by the user, are deleted. initialisation he re-initialisation is started by switching the measuring instrument on and by ressing the following keys within 3 seconds: version 1.xx 1 2 and and (. 1-2 ) Afterwards you can choose among German, English or French as your oeration language by ressing key (, which is now acting as a cursor. 1-2 ) LANGUAGE English he selection needs to be confirmed with key. ( 1-2 ) French ( 1-2 ) German ( 1-2 ) * * * * * UNI * * * * SI After this, the dislay for the selection of SI- or US units of measurement aears automatically. With key that is now acting as a cursor, you can ( 1-2 ) switch between SI- and US units of measurements. ( 1-2 ) US he SI-units are for examle bar, C, l/min., etc.. After the change-over to US-units, the usual units like si, F, gal/min. are used. INI? (bar) 2 (bar) PROG->Yes he instrument automatically asks for the initialisation. Here you can decide whether you want to initialise or not. If no initialisation is requested any key excet / may be ressed and the measuring value dislay is shown. If you request an initialisation, ress key and all data like calibration value, units of measurement, selection of the outut signal of the ressure sensors, entered reviously, is deleted. -9-

10 INI? PROG->Yes INI? If you request an initialisation, ress key o and all data like calibration value, units of measurement, selection of the outut signal of the ressure sensors, entered reviously, is deleted. For a short moment, the dislay shows INI together with a rotating bar, which indicates, that the arameters, entered by you, are deleted and overwritten by the basic adjustments. Afterwards the instrument returns directly into the measuring value dislay After an initialisation, the following basic adjustments are valid: Pressure measurement 1 and 2 in the dislay Pressure measuring range rogrammed to 0 to 200 bar Signal inuts of 1, 2,, Q and N adjusted to 0 to 20 ma Measuring units in SI -10-

11 2. ramming 2.1 Selection of ressure sensor for signal 0 to 20 ma or 4 to 20 ma As it is ossible to connect ressure sensors with an outut signal of either 0 to 20 ma or 4 to 20 ma, it is imerative to inform your measuring instrument about the signal-tye of your sensor. By ressing key and key, the following rogramme is invoked * * PROG SENSOR YPE * 1: : 0-20 ma : 0-20 Q : 0-20 N : : ( 1-2 ) he change-over to 4 to 20 ma is made by a stroke of key ( 1-2 ), which is now acting as a cursor and which switches 1 to the requested current signal. Please take into consideration, that a flashing bar signalises the switching from 0 to 4 (ma) in the examle. A stroke of key, which is also used as a cursor in this case, switches directly to 2. Here the current signal can be switched to 4 to 20 ma with key (, too, as already mentioned above. 1-2 ) he switching back to 0 to 20 ma is made in the same way. Please don t forget to ress key / to confirm your selection. In the examle the ressure sensor 2 was switched to 4 to 20 ma, of course the adjustments of every single channel can differ. With the cursor key, showing to the right, the corresonding measuring channel will be selected. With the cursor key, showing uwards, the current range 0 to 20 ma or 4 to 20 ma can be selected. he selection must be confirmed with key. -11-

After this, the measuring value dislay will be shown automatically. * * PROG SENSOR YPE * 1: : 4-20 ma : 0-20 Q : 0-20 N : 0-20 As an examle you can see here a dislay after having switched the ressure channels 1 and 2 to 4 to 20 ma. 2.2 Checking of current signal adjustment * * PROG SENSOR YPE * 1: : 4-20 ma : 0-20 Q : 0-20 N : 0-20 Measuring value dislay 3 s You have the ossibility to check which current signals were chosen, when invoking this dislay with key In the examle the same current signals were chosen for 1 and 2. After arox. 3 seconds, the dislay returns automatically into the measuring value dislay Error message at 4 to 20 ma sensors 1 2 If this dislay aears, no current signal is lead to the measuring inut. A reason for this error can be missing connections (a missing measuring cable) between sensor and measuring inut, a arting of a cable or a defective sensor. In this case, you will be directly informed about ossible errors by an otical status dislay (life-zero recognition). his visual signal is only ossible for the signals of 4 to 20 ma. Please take into consideration, that different adjustments of the current signals can be made for ressure sensors (1 and 2). For examle: 2 = 4 to 20 ma 1 = 0 to 20 ma 2.4 Measuring value dislay at 4 to 20 ma sensors If the ressure sensor works correctly, the measuring value dislay will be shown in the usual way without horizontal lines. -12-

Starting from menu PROG P1 you select the rogramme Zero oint alignment by ressing key (. 1-2 ) Please ay attention that your selection is marked with a star symbol * and that it is confirmed with key afterwards. For the zero oint alignment the ressure sensor 1 must be removed from the lant what means, that the alignment must always be carried out on a deressurized sensor. If the sensor has no ressurisation its zero oint can be aligned with a stroke of key. * * * * * * * PROG * * * * * * * he dislay shows WAI. he zero oint deviation of the ressure sensor is determined and stored as a correction value while a rotating bar is dislayed After the zero oint alignment the measuring value dislay is shown automatically. If ressure measurements are carried out now, an existing zero oint deviation is taken into consideration by the internal software as a correction value for all measurements. If you want to carry out a zero oint correction for another ressure sensor, e.g. 2, you should act as described above. You only have to ress keys and 2 instead of and

15 3.3 Measurement of ressure eaks 3.4 Invocation of min./max. values in the dislay 1^ 0.0 / he min./max. values of ressure 1 and 2 are continuously stored in a memory in the background and can be shown in the dislay on request. his is made by a stroke of the keys and. o be able to see the min./max. values in the lower line, too, 2 ress the keys and. 1 1^ 42.2 / ^ / min.-value or max.-value for ressure 1 and 2 he min./max. values can only be shown for the ressure of 1 and 2. Please take into consideration, that a measurement of ressure eaks is only ossible u to the ressure measuring range end value of the ressure sensor, chosen by you, with an additional tolerance of max. 10%. he ressure measuring range end value 600 bar for examle, lus additionally 10%, results in a maximum ressure eak value acquisition of 660 bar. Higher ressure eaks will be limited to 660 bar. 3.5 Deletion of ressure eak 1^ 42.2 / ^ / By ressing the keys and, you can delete the min./max. value memories of 1 and 2. he note, that both min/max. memories are deleted, is shown briefly in the dislay. * * * * DELEE * * * * * MIN/MAX-MEMORY If the ressure sensors measure certain oerational ressures, the extreme value memories will be set back to these ressure levels. 1^ / ^ / As an examle, a deletion and a setting back to the oerational ressures that are existing in the hydraulic lant at that moment, are shown. 3.6 Change-over from measurement of ressure eaks to normal ressure measurement With a stroke of key and key, you can switch the instrument back to normal ressure measurement. he examle shows the switching over to ressure 1 and 2 (both keys have to be ressed one after the other). -15-

16 3.7 Measurement of ressure differential Precise ressure differential measurements are only ossible, if both ressure sensors are aligned at the oerational ressure, which will be used for the later measurement. Of course this is the same ressure for both ressure sensors. o carry out a ressure differential alignment, you have to mechanically connect both ressure sensors 1 and 2 to the same ressure level via a distributor (see scheme Pressure differential alignment ). You can also use ressure sensors with different ressure measuring ranges, but in this case you should always ay attention to their ressure load on the sensor to avoid a damage of the sensor. In the examle an oerational ressure of 308 bar is shown in the dislay d * * * PROG dp * * * alignment 2 sec he change-over with key shows a ( 1-2 ) ressure differential of 0,5 bar. With a stroke of the keys and ( 1-2 ) you can carry out an automatic alignment for arox. 2 seconds, what is shown in the dislay. he deviations of both ressure sensors are set to zero at the corresonding oerational ressure level, see dislay (ressure differential of both ressure sensors = zero). After the alignment you have to mechanically connect the ressure sensor 2 to the connection B (see scheme Pressure differential alignment ). 1 d Now you can carry out recise measurements of ressure differential without being influenced by sensor deviations, temerature drifts and offsets. Please take into account, that a ressure differential is always dislayed with the correct sign, corresonding to the mathematical formula. (q = 1-2). -16-

17 4. Measurement of temerature 1 [ C] Instead of ressure 2 a Pt 100 temerature sensor with a current outut signal of 0 to 20 or 4 to 20 ma can be connected to this measuring inut. You only have to ress key Q as long as the n second line of the dislay shows in ( C). he temerature measurement is shown in the lower line of the dislay. Single dislay for temerature he temerature measurement is shown in the lower line of the dislay [ C] If you want the temerature measuring value to be dislayed, only, ress the keys 1 and Q, one after each other. n he way to switch over the current signal from 0 to 20 ma to 4 to 20 ma and vice versa, is already described on age 11, chater 2.1, for ressure sensors. Please take into account, that the temerature measuring range is fixed (calibration: -50 C to +200 C). 1 [ C] If ( C) -50 is dislayed, the temerature sensor isn t connected to the measuring instrument. his is only valid for the adjustment of sensor tye 0 to 20 ma. 1 [ C] If ( C) is dislayed, the temerature sensor isn t connected to the measuring instrument. his is only valid for the adjustment of sensor tye 4 to 20 ma. -17-

18 5. Measurement of volume flow rate 1 Q [l/min] A condition for the measurement of volume flow rate is the connection of a measuring turbine or a gear flow meter with integrated F/DC-converter. hat means, the frequency signals measured by the volume flow rate sensor must be converted into current signals from 4 to 20 ma. Key Q needs to be ressed until Q in (l/min) is n shown in the second line of the dislay. 5.1 Inut of calibration value * * * PROG Q * * * *calibr. value zero oint PROG -> confirm When connecting a volume flow rate sensor, for examle turbine or gear flow meter, the max. volume flow rate needs to be entered as a calibration value. he rogramme for entering this calibration value is invoked with the keys and Q. n Key ( 1-2 ) serves for the switching between the inut of the calibration value and the zero oint alignment. * * * PROG Q * * * MAX : [l/min] Please take into consideration, that the star * marks the selected line, in this examle the line calibration value. With key the selection needs to be confirmed and instrument immediately asks for the inut of the max. volume flow rate (measuring range end value). he max. volume flow rate can be seen on the label of the volume flow rate sensor, in the examle the max. volume flow rate is l/min. he inut is made as already described on age 13, aragrah 3.1, however for volume flow rate sensors you have to rogramme the end of the measuring range, only. 5.2 Zero oint alignmenth * * * PROG Q * * * calibr. value *zero oint PROG -> confirm Starting from menu Q the key serves for ( 1-2 ) the switching between the inut of the calibration value and the zero oint alignment. In the examle the zero oint alignment is selected ( *!) and confirmed with key. Please carry out the zero oint alignment as described on age 14, aragrah

Measurement of rev. seed 6.1 Inut of calibration value * * * PROG N * * * *calibr. value zero oint PROG -> confirm A condition for the measurement of RPM is the connection of a rev. seed sensor with integrated F/DC-converter. hat means, the frequency signals measured by the rev. seed sensor must be converted into current signals from 4 to 20 ma. When connecting an otical rev. seed sensor with F/DCconverter to the instrument, the calibration value needs to be entered as follows: - when using one reflective foil, the calibration value 9999 needs to be entered - when using more than one reflective foil, the calibration value can be calculated as follows: : Number of reflective foils = calibration value When connecting an inductive rev. seed sensor with F/ DC-converter, e.g. acquisition of the RPM at a gear ring, the calibration value is calculated as follows: : Number of ulses er rotation (number of teeth) = calibration value he rogramme for the inut of the calibration for the rev. seed sensor is invoked with the keys Q. he following dislay is shown. n and * * * PROG N * * * MAX : 9999 [U/min] Key ( serves for the switching between calibration value and zero oint 1-2 ) alignment. Please take into consideration, that the star * marks the selected line, in this examle the line calibration value. With key the selection needs to be confirmed and instrument immediately asks for the inut of the max. rev. seed (measuring range end value). he max. rev. seed can be seen on the label of the rev. seed sensor, in the examle the max. rev. seed is: 9999 rm (referring to one reflective foil). he inut is made as already described on age 13, aragrah 3.1. Starting from menu N the key ( 1-2 ) serves for 6.2 Zero oint alignment * * * PROG N * * * calibr. value *zero oint PROG -> confirm the switching between the inut of the calibration value and the zero oint alignment. In the examle the zero oint alignment is selected ( *!) and confirmed with key. Please carry out the zero oint alignment as described on age 14, aragrah

20 6.3 Further technical advice for the measurement of rev. seed he rev. seed robe DS 03 with F/DC-converter, used by HYDROECHNIK, is working as a reflective light barrier, that means, the light-sender as well as the receiver are situated in one housing. o measure rev. seed the user only has to stick-on a reflective foil on the turning object to be measured. Pollution, borings or keyways are suressed effectively by the measuring rincile (olarisation filter), only the light reflection of the foil is evaluated as a turning ulse. At very large diameters of shafts or fans it can haen, that instable or interruted rev. seeds are dislayed. If this is the case, the number of reflective foils should be increased, that means several foils need to be stuck on the object to be measured, one besides the other. his will imrove the otical scanning and a correct measurement of rev. seed is achieved. If you request rev. seed measurements below 60 min -1, you can realise this by sticking-on several reflective foils. In any case you should modify the inut of the ulses er rotation (see above) and take the instructions for the inut of calibration values on age 18, aragrah 6.1, into consideration. Rev. seed measuring range relating to one reflective marking: 60 min -1 to 9999 min -1. If you request measurements of rev. seed on gear wheels, an inductive transducer with integrated amlifier and F/DC-converter needs to be used. Here, the number of teeth of the gear wheel needs to be entered into the measuring instrument as ulses er revolution, too (see aragrah 6.1 on age 18). he ideal distance for sticking on the reflective markings deends on the form of the teeth. Usually the distance between the inductive transducer and the tooth is 1 to 2 mm. For these very small measuring distances the sensor needs to be fixed very safe and stable. -20-
