ZEROTESTpro How to display additional measured / calculated results on the display Basic display mode - press and release the DISP▲ or DISP ▼ key. Following results are displayed successively: calculated prospective fault/short-circuit current, measured Loop/Line resistance multiplied by a factor 1.5, Loop/Line resistance result which takes into account the measurement error and finally measured Loop/Line resistance again. - Page 15 ZEROTESTpro • After displayed voltage is stabilized, press and release the ~ / RCD key. The measurement of Line resistance is executed (it is necessary to measure it before Loop resistance measurement is executed). Ensure good contact between the test tips and the measured object. After the measurement is finished, the Line resistance measurement result is displayed and the symbol „~“...

• There is the database (table) of fuses’ types/disconnecting times/rated currents in the memory of the ZEROTESTpro. There are displayed fuse type, rated current and disconnecting time (example in the Fig. 3.16). When the T key is pressed first time, the minimal required fault current is displayed. - Page 17 ZEROTESTpro Fig. 3.17a Phase voltage present on Fig. 3.17b Phase voltage present on the test tip (Basic display mode) the test tip (Detailed display mode) Note: To avoid wrong results, following prerequisites must be met: You have to hold the instrument in hand (palm) in a standard way! You have to stand on non-insulated floor! The test tip has to be connected to a voltage at least 2 seconds.

Page 20: Charging Of Accumulators
ZEROTESTpro 4.1.2. Charging of accumulators For charging of accumulators use only adapter supplied as optional accessories! Accumulators are charged as soon as the adapter is connected to mains and to socket for accumulators charger (see Fig. 2.1). If accumulators are fully discharged, the charging takes about 6 hours (applies to batteries with a capacity of 800 mAh). -
Page 21: Replacing The Fuse
ZEROTESTpro 4.1.3. Replacing the fuse Replace the fuse by the same type only: F1A/500 V, breaking capacity 1500 A, dimensions 32x6,3 mm. Using of another type of fuse can cause damage of the instrument and/or operator’s safety can no longer be guaranteed! For replacing the fuse unscrew two screws and remove the batteries / fuse compartment cover, see Fig. -
