Whe selectig a rage with the fuctio selector switch (6), the DC fuctio is always set by default. Coect the multimeter i series with the load, as show. Esure that the coectios are tight (with least resistace). Notes o Curret measuremet The multimeter must be used oly i the power systems, where the curret circuit is protected by a fuse or a circuit breaker of 20 A, ad whe the omial voltage of the system does ot exceed1000v AC/DC. Make the measurig circuit coectios mechaically strog ad secure so that they do ot accidetally ope. The coductor cross 10

12 sectios ad coectio poits should be desiged to avoid excessive heatig. The curret measurig rages up to 660 ma are protected to a short circuit curret of 25 A by a fuse 1.6 A/1000V AC/DC i cojuctio, with power diodes. The cut-out capacity of the fuse is 10kA at a rated voltage of1000v AC/DC ad ohmic load. The 10 A curret measurig rages are protected by a 16A/ 1000V AC/DC fuse. The cut-out capacity of the fuse is 30 ka at a ormal voltage of 1000V AC/DC ad ohmic load. Replacemet of the fuses is described i sectio 17. Maiteace. Cautio The measurig rages 16 A of Multimeter NP10-3 are ot protected by a fuse! 10.1 AC curret measuremet with (clip-o) curret trasformer Trasformer output ma/a Cautio If curret trasformers are operated with a ope circuit o the secodary side, e.g. due to defective or discoected leads, a blow fuse i the meter, or a wrog coectio, dagerously high voltages ca occur at the coectors. Therefore, verify that the curret circuit of the multimeter ad secodary widig of trasformer coected to the multimeter form a itact circuit. Coect the trasformer to the sockets ad ma or A The maximum permissible operatig voltage is the omial voltage of the curret trasformer. Whe readig the measured value, take ito accout the trasformer ratio ad the additioal error i idicatio. Trasformer output Multimeter NP10-2 The multimeter NP10-2 shows the switchig positio ad the correspodig sockets. Coect to this socket a (clip-o) curret trasformer with a trasmissio ratio of 1000:1 the the measured values are displayed directly i the A rage Trasformer output V May trasformers have voltage output (refered as mv/a) The secodary output must therefore be coected to the coectio sockets ad V. 11

Maiteace Cautio Discoect the meter from the measurig circuit before you ope it to replace the battery or the fuse! Battery Prior to iitial start-up, or after storage of multimeter, verify that the cells of multimeter does ot leak. Repeat this check i regular short itervals. If the cells leaks, completely remove the cells carefully with a moist cloth ad istall a ew cells before you operate multimeter agai. Whe the symbol (17) appears o the LCD (1) replace the cells as soo as possible. Measuremet ca be doe, but a reduced measurig accuracy must be take ito accout. The multimeter operates with 2 AA size batteries alkalie magaese cells as per IEC LR6 Replacig the Battery Place the multimeter o its face, loose the sigle screw preset o the rear side ad remove the battery cover from bottom side. Remove the cells from the battery compartmet ad replace them with the ew cells (for specificatios refer Power supply ). Tighte the battery cover with the screws. 25

27 17.2 Fuses The 16 A fuse protects the 10 A rage, the 1.6 A protects 66mA,660mA curret measurig rages. Whe a fuse blows, first elimiate the cause of the overload before usig the multimeter agai! Replacig the Fuses Place the multimeter o its face, loose the two bottom cover screws o the rear ad remove the bottom cover by, liftig it from the bottom. Remove the faulty fuse from the fuse holders. Remove the blow fuse, e.g. with the aid of a probe, ad replace it with a ew oe. Tighte the bottom cover with the two screws. Types fuses for curret measurig rages up to 660 ma: For curret measurig rages up to 660 ma: --FF (UR) 1.6 A / 1000 V AC/DC ; (10 ka) ; 6.3 mm x 32 mm For 10A curret measurig rage: --FF (UR) 16 A / 1000 V AC/DC ; (30 ka) ; 10 mm x 38 mm Cautio Absolutely verify that oly the specified fuse is istalled! If a fuse of other cut-out capacity, other omial curret or other switchig capacity is used, a dagerous situatio exists, ad there is dager of damagig protective diodes, resistors or other compoets. The shortig of the fuse holder is ot permissible Case Special maiteace of the case is ot required.take care that the surface betwee the coectio sockets is clea. For cleaig take a moist cloth. Avoid scrabbig. 26
