1 Functons Mechancal characterstcs The MarSurf M 300 s a compact surface texture measurng nstrument for moble use under shop floor condtons. The maxmum measurng range s 350 μm (0.014 n) (-200 μm to +150 μm) (-0.008 n to +0.006 n). Wth the correspondng MarSurf RD 18 drve unt measurements can be performed n any measurng poston wthout the need for setup tmes. The maxmum traversng length s 17.5 mm (0.700 n). The nstrument s easy to use and comples wth DIN EN ISO 3274. The MarSurf M 300 and all Mahr pck-ups are balanced at the factory. For hgh-precson measurements usng the stylus method and subsequent checks, an automatc dynamc calbraton functon s avalable. A standard s ntegrated n the MarSurf RD 18 for ths purpose. 1 PHT pck-ups have an nnovatve open skd 1 that vrtually elmnates deposts of drt and ol. The bow-type vertcal adjusters 2 for settng the heght of the MarSurf RD 18 drve unt allow many dfferent forms of support (stable threepont support, four-pont support, e. g. for cylndrcal testpeces, combnaton wth the pck-up protecton, etc.) and make vertcal adjustment very easy. The rugged housng makes the MarSurf M 300 deal for operaton under severe condtons. The nstrument combnes an ergonomc desgn wth clearly arranged operatng elements and a large, easy-to-read LCD. Its compact form and low weght (approx. 1 kg / 2.21 lbs) make t deal for moble use. Thanks to the transport case and the shoulder belt, t s easy to carry around. The bult-n rechargeable battery offers enough capacty for several days work 3. The nstrument s AC adapter comes wth three exchangeable mans adapters, allowng the MarSurf M 300 and ts RD 18 drve unt to be connected drectly to the mans all over the world. Possble nstrument settngs All the functons supported by the nstrument are set out n a logcally structured menu. Instrument settngs can be blocked and also protected aganst unauthorzed modfcaton by means of a code number. The operator can swtch between ISO (DIN), ASME, JIS and MOTIF standards to select the traversng length and for evaluaton purposes. When measurements are performed n accordance wth ISO (DIN), ASME or JIS, the recorded profle s fltered wth a phase-correct profle flter (Gaussan flter) complyng wth DIN EN ISO 11562. A shorter cutoff can also be selected for ths purpose. Even nexperenced users can perform correct, reproducble surface texture measurements: If ths functon s actve, the nstrument detects perodc and aperodc profles and automatcally sets the standard cutoff and assocated traversng length n accordance wth DIN EN ISO 4288. 1 1 patented 2 Patent pendng 6 3 The capacty s suffcent for approx. 1,000 measurements (dependng on the traversng length and the settngs n the "Record" menu). Mahr GmbH, MarSurf M 300 and RD 18
Evaluaton Most of the parameters stpulated n ISO (DIN), ASME, JIS and MOTIF are avalable to evaluate the measured profle (see Secton 5.3). The evaluaton condtons can be set, e.g. reference lne and ntersecton lne for materal rato Rmr (equv. to tp n accordance wth ASME and JIS), symmetrcal or asymmetrcal ntersecton lnes for peak count RPc, operators A and B for the MOTIF evaluaton, and ntersecton lnes for zone wdths CR, CF, CL. In order to montor tolerances, tolerance lmts can be set for all selected parameters. If lmts are exceeded, ths s ndcated on the dsplay and n the measurng record. Results and settngs can be dsplayed usng ether the metrc or the Imperal system of unts. The ntegrated thermal prnter wth graphcs support can output entre measurng records wth characterstc curves and profle dagrams as well as ndvdual functons, e. g. an ndvdual lst or curve. The nternal USB memory can store up to 30 profles or 40,000 results. Interfaces Usng Bluetooth technology, the MarSurf M 300 can be connected wth varous MarSurf RD 18 drve unts (see Secton 4.3.3). The nstruments comply wth Bluetooth specfcaton 2.0. The "MarSurf PS1 / M 300 Explorer" software (see Secton 10) enables records of the profles and measurng results to be saved and prnted. The MarConnect nterface can be used to start the nstrument remotely. Accessores The extensve range of accessores for the MarSurf M 300 and RD 18 enable a wde varety of applcatons (see Secton 10): The end face vee-block allows measurements on end faces of planar and cylndrcal workpeces. For testpeces such as crankshafts or camshafts whch are measured n the axal drecton, an optonal adapter for transverse tracng s avalable.

Open the "Measurng condtons" menu by pressng the key. 2. Press the 1 key to dsplay "ISO / ASME / JIS" n the respectve button. On the rght sde the measurng and evaluaton condtons n accordance wth ISO / ASME / JIS wll be dsplayed. Selectng the traversng length The top status bar (5) dsplays the length of the traversng length Lt, the length of the cutoff Lc and the number n of samplng lengths, e. g. "Lt=5.600mm (0.800*5)" (see Fg. 2). 1. Press the Lt/Lc key repeatedly untl the requred cutoff and the resultng standard traversng length are dsplayed. If "Lt=*****mm (******5)" s dsplayed for Lt and Lc nstead of a value and the symbol A appears to the rght, the automatc settng of cutoff and traversng length has been set. The length of the traversng length n accordance wth ISO, ASME or JIS s determned by the cutoff, whch s to be selected accordng to Table 2. Three cutoffs are avalable wth the MarSurf M 300. The cutoff defnes whch elements of the measured profle wll be attrbuted to roughness. Lt Lc n lm 1.750 mm (0.250 * 5) 5.600 mm (0.800 * 5) 17.50 mm (2.500 * 5) 0.070 n (0.010 * 5) 0.224 n (0.032 * 5) 0.700 n (0.100 * 5) 1.250 mm 4.000 mm 12.50 mm 0.050 n 0.160 n 0.500 n Tab. 1 Avalable traversng lengths (and cutoffs) n accordance wth ISO, ASME, JIS Usually the traversng length conssts of the pre-travel Lv, fve samplng lengths lr (= evaluaton length lm) and the post-travel Ln. The samplng lengths and the pre- and the post travel are exactly as long as the standard cutoff (see Table 2). Mahr GmbH, MarSurf M 300 and RD 18 19
If the automatc settng (symbol A) of cutoff and traversng length s swtched on, durng the measurement the nstrument frst checks f t s a perodc profle: Wth a perodc profle, the nstrument automatcally sets the standard cutoff and assocated traversng length accordng to the RSm value (see Table 2). Wth an aperodc profle, the cutoff and traversng length are set automatcally accordng to the Rz value (see Table 2). The settngs calculated for Lt and Lc are dsplayed n the top status bar after the measurement has been carred out. Swtchng the Ls profle flter on/off If the Ls profle flter s swtched on, the profle s fltered after the measurement wth a cutoff wavelength of 2.5 μm or 8 μm (100 μn or 320 μn), dependng on the traversng length. The Ls profle flter can also be swtched on and off n the "Measurng staton" vew. Swtchng profle nverson on/off Usually a profle s evaluated n the same way that t s measured,. e. profle peaks are also handled as such. However, for replca measurements profle nverson should be swtched on. Ths causes the measured profle to be mrrored on the dagram mean lne so that the evaluaton s based on a profle n the correct poston. If a profle s evaluated wth profle nverson, the profle type s dsplayed n the "Result" vew wth a mnus sgn (e. g. "R " or "P "). For the followng parameters, the measurng value s affected by profle nverson: Rp, RpA, Rpm, Rv, Rpk, Rk, Rvk, Mr1, Mr2, A1, A2, Vo, RPc, Rmr, tp, RSm, S, Rsk, R, AR, Rx, W, CR, CF, CL. Selectng the number of samplng lengths If standard traverse lengths cannot be used wth the testpece, n accordance wth the standard, the number n of samplng lengths can be reduced or ncreased. 13 If n 5, the symbol appears n the top status bar. By selectng a standard traversng length wth Lt/Lc, the number n of samplng lengths s reset to 5. Selectng the cutoff When evaluatng n accordance wth ISO, ASME or JIS, dgtal flterng generates the roughness profle from the measured profle. The phase-correct profle flter (Gaussan flter) s used. When evaluatng the parameters n accordance wth DIN EN ISO 13565-2, the specal flterng method wth groove suppresson as per DIN EN ISO 13565-1 s used. The flter s characterzed by the cutoff. The cutoff s the wavelength Lc of a snusodal profle, the ampltude of whch wll be transmtted by the phase-correct flter to a level of 50 %. The cutoff defnes whch elements of the measured profle wll be attrbuted to the roughness. The cutoff and traversng length are selected together before the measurement by pressng Lt/Lc. DIN EN ISO 4288 states that the cutoff for standard measurements should be selected as follows: for perodc profles, accordng to the mean wdth RSm of the profle elements, or Rz (see Table 2). and for aperodc profles, dependng on Ra 13 If the automatc settng A of cutoff and traversng length s set, the number n of samplng lengths cannot be modfed. 20 Mahr GmbH, MarSurf M 300 and RD 18
In specal cases, the next shortest cutoff may be used nstead of the standard one requred by ISO 4288. The "Lc short" settng can also be mplemented after the measurement. 14 After the settng s made, the cutoff value s dsplayed n the top status bar (5) (see Fg. 2). When the short cutoff s swtched on, the symbol appears n the top status bar. If a standard traversng length s selected by pressng Lt/Lc, the short cutoff s deactvated agan. Selectng the length of the pre- and posttravel If standard traverse lengths cannot be used wth the testpece, the pre-travel Lv and posttravel Ln can be shortened 15. In the settng "Lv short" Lv and Ln are half as long as the standard cutoff. When the short pre- and post-travel are swtched on, the symbol appears n the top status bar. By selectng a standard traversng length wth Lt/Lc the short pre- and post-travel are swtched off agan.

Settng the ntersecton lnes for peak count 35 36 37 To calculate the peak count RPc, an upper ntersecton lne C1 (35) and a lower ntersecton lne C2 (37) are placed nto the roughness profle. Both ntersecton lnes are parallel to the dagram mean lne (36). The dstance (n μm or μn) from the ntersecton lnes to the dagram mean lne can be set to symmetrcal or asymmetrcal values. 16 To set a symmetrcal dstance from the ntersecton lnes C1 and C2 to the dagram mean lne: 1. Set the upper ntersecton lne C1. The value for the lower ntersecton lne C2 s automatcally set to -C1. To set an asymmetrcal dstance from ntersecton lnes C1 and C2 to the dagram mean lne: 1. Frst set the value for C1. The value for the lower ntersecton lne C2 s automatcally set to -C1. 2. Then select the "C2" button by pressng the key and set the desred dstance C2 for the lower ntersecton lne. If the value s negatve, the ntersecton lne les below the dagram mean lne. Each tme the value for C1 s changed, C2 s reset to -C1. If C2 -C1 s requred, C2 must then be reset. Fg. 7 Intersecton lnes for peak count 35 Upper ntersecton lne C1 36 Dagram mean lne 37 Lower ntersecton lne C2 Settng the reference lne and the ntersecton lne for the materal rato To calculate the materal rato Rmr (tp for ASME), an ntersecton lne C (level p for ASME) (45) s placed nto the profle. The poston of ths ntersecton lne s determned by ts dstance (n μm or μn) to the reference lne CREF (40). The reference lne s parallel to the dagram mean lne; ts poston s determned by a materal rato value (e. g. "CREF 5.0 %"). 40 45 46 Fg. 8 Reference lne and ntersecton lne for materal rato 16 The values for C1 and C2 should be entered n steps of 0.1 μm.

Three dfferent ntersecton lnes "C" or "p" can be set so that three ndvdual values for Rmr or tp can be output. If the value s negatve, the ntersecton lne les below the reference lne. For the materal rato lst ("Rmr lst", "tp lst" for ASME; see Secton 5.2.2) the hghest value "C" or "p" (. e. the button below "CREF") determnes the dstance of the frst ntersecton lne (45) from the reference lne (40) and the dstance of the ntersecton lnes (46) from each other. 3.5.4 Measurng and Evaluaton Condtons n Accordance wth MOTIF To dsplay the measurng and evaluaton condtons n accordance wth MOTIF: 1. Open the "Measurng condtons" menu by pressng the key. 2. Press the 1 key to dsplay "MOTIF" n the respectve button. On the rght sde the measurng and evaluaton condtons n accordance wth MOTIF wll be dsplayed. Selectng the traversng length The top status bar (5) dsplays the length of the traversng length Lt, e. g. "Lt =16.00 mm" (see Fg. 2). 1. Press the Lt/Lc key repeatedly untl the requred traversng length s dsplayed.

The Ls profle flter can also be swtched on and off n the "Measurng staton" vew. Swtchng profle nverson on/off Usually a profle s evaluated n the same way that t s measured,. e. profle peaks are also handled as such. However, for replca measurements profle nverson should be swtched on. Ths causes the measured profle to be mrrored on the dagram mean lne so that the evaluaton s based on a profle n the correct poston. If a profle s evaluated wth profle nverson, the profle type s dsplayed n the "Result" vew wth a mnus sgn (e. g. "R " or "P "). For MOTIF parameters, the measurng value s affected by profle nverson. Settng the operators for MOTIF evaluaton When calculatng the measurng results for the MOTIF parameters, operators are used whch defne the maxmum length (n mm or n) of the roughness motfs (operator A) or the wavness motfs (operator B). ISO 12085 states that operators A and B are selected accordng to the expected length of the motfs. Unless otherwse specfed, the default values are A = 0.5 mm and B = 2.5 mm.
