nizing the dangers associated with the measurement of electrical current and voltage. Read the operating instructions completely and carefully before using the device, and follow all instructions included therein.
! Attention! Do not perform measurements in the event of over-ranging! Current which exceeds the measuring range may not be measured. Do not perform measurements at bare wires! Do not perform measurements at busbars! Safe Handling • The housing and the handles must be free of dust, grease and moisture. • The operator’s fingers may not be extended beyond the safety collar during measurement.
teresis due to magnetization. As a result, the zero adjustment point for DC measurements may vary. Open and close the clip jaws several times in a row and press the ZERO ADJ key prior to each DC measurement in order to elimitate this effect. When measuring current conducting cables, close and open the clip jaws slowly and firmly in order to avoid any impact on the sensitive hall effect sensor.
2.2 Stipulations for All Measurements ! Attention! In order to prevent damage to the instrument and the user, the maximum input quantities may not be exceeded: Voltage range 300 V AC/DC, current range 20 A AC/DC. Note Exercise caution when opening and closing the clip jaws around an active conductor.
mode is deactivated. Press the key again to cancel this function. Selecting Current Type – ACA / DCA The measuring instrument is always set to direct current when switched on. Press the ACA or DCA key to change to the other current type. Zero Balancing or Reference Value Function – ZERO ADJUST Zero Balancing for DC measurements DCA Even if the clip jaws are not closed around a conductor, measured values are continuously displayed when the measuring instrument is set to DC measurement.
2.3 ➭ ➭ ➭ ➭ ➭ ➭ ➭ 10 Measuring Leakage Current at Grounded Conductors Turn the measuring instrument on with the POWER key. Select the current type via the ACA or DCA key. Set the RANGE UP or RANGE DOWN key to the appropriate range for the current to be measured. Otherwise, set the measuring range switch to the highest of the three ranges in order to avoid possible over-ranging. Prior to DC measurements: Perform zero balancing via the ZERO ADJUST key.
2.4 ➭ ➭ ➭ ➭ ➭ ➭ ➭ Measuring Leakage Current at Single-Phase or 3-Phase Systems Turn the measuring instrument on with the POWER key. Select the current type via the ACA or DCA key. Set the RANGE UP or RANGE DOWN key to the appropriate range for the current to be measured. Otherwise, set the measuring range switch to the highest of the three ranges in order to avoid possible over-ranging. Prior to DC measurements: Perform zero balancing via the ZERO ADJUST key.
2.5 Measuring Line Current ➭ Turn the measuring instrument on with the POWER key. ➭ Select the current type via the ACA or DCA key. ➭ Set the RANGE UP or RANGE DOWN key to the appropriate range for the current to be measured. Otherwise, set the measuring range switch to the highest of the three ranges in order to avoid possible over-ranging. ➭ Prior to DC measurements: Perform zero balancing via the ZERO ADJUST key. ➭ Close the clip around a single current conducting cable only.

4 Maintenance 4.1 Battery Replacement If the battery symbol B appears at the display, the batteries are either depleted or no longer supply sufficient operating voltage, and must be replaced. The batteries should also be removed if the instrument is placed into storage for a lengthy period of time, because leakage might otherwise occur. ! Attention! Remove the clip from the measuring circuit first. Only then may the battery compartment lid be removed in order to replace the batteries.
Note Always replace both batteries at once. ➭ Slide the battery compartment lid back into place so that the two pins engage in the recesses provided. ➭ Reinsert and tighten the screw. Note The measuring instrument does not include any replaceable fuses! 4.2 Housing No special maintenance is required for the housing. Keep outside surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the use of cleansers, abrasives and solvents.
