1. Safety Safety Information To ensure safe operation and service of the Tester, follow these instructions. Failure to observe warnings can result in severe injury or death. - Avoid working alone so assistance can rendered. If the operators safety can not be guaranteed, the Tester must be removed from service and protected against use.
2. Symbols and Features Symbols as marked on the Tester and Instruction manual Risk of electric shock See instruction manual + or - + DC or –DC measurement Equipment protected by double or reinforced insulation Battery Earth ...

3. AC/DC V Measurements AC V DC V IVT-10 : The safety LED can report a dangerous voltage> 50 V AC and 120 V DC IVT-20 : The safety indicator can report a dangerous voltage > 50 V AC and 120 V DC.
5. Resistance Measurements Only on IVT-20 The Resistance test is only possible when batteries are installed and in good condition. 6. Single-Pole Phase Test Single-Pole Phase Firmly →...
The single-pole phase test is only possible when batteries are installed and in good condition. The single-pole phase test is not always appropriate for testing whether a circuit is not live. For this purpose, the bipolar test is required.

Left rotary field Firmly → Testing of phase-sequence direction is possible from 100V AC voltage (phase to phase) provided the neutral is earthed. On making contact with both test electrodes (probe tips) to two phases of the three-phase power supply which are connected in clock- wise rotation, a “B”...

10mA or 30mA by measuring the voltage between L and PE. These Testers IVT-10 / IVT-20 are equipped with an internal load enabling the tripping of an RCD protection device of 10mA or 30mA.
Page 11
To avoid RCD tripping, a test has to be carried out between L and N during approx. 5sec. Immediately afterwards, voltage testing between L and PE can be carried out without RCD tripping. 9. Illumination Probe tip torch...
10. Frequency Tests Only on IVT-20 11. Auto Tests If the instrument shows failue, please don’t use it and send it to our service department for repair.
12. Battery Replacement If no signal sound is audible (IVT-10) when short circuiting the test probes, if the symbol “<” is displayed (IVT-20) - Completely disconnect IVT-10 /IVT-20 from the measurement circuit. - Unscrew the screw by a cross screw driver, then open the battery cover.
16. Maintenance Unauthorized persons shall not disassemble the tester and the supplementary equipment. When using tester IVT-10 /IVT-20 testers in compliance with the instruction manual, no particular maintenance is required. If functional errors occur during normal operating, our service department will check...
