Page 4: Safety Precautions
Safety Precautions You have selected an instrument which provides you with a high level of safety. The METRAVOLT 12D+L voltage tester has been manufactured and tested in accordance with requirements set forth in DIN EN 61243-3 (VDE 0682 part 401) regarding 2-pole voltage testers. -
Page 5: Initial Start-Up
Initial Start-Up Battery Your instrument is supplied with an installed 9 V block battery in accordance with IEC 6 LR 61. Attention! Be sure to refer to chapter 6.1 before initial start-up, or after your device has been in storage for a lengthy period of time. Testing for Correct Display and Function According to DIN VDE 0105 part 1, voltage testers must be tested for correct functioning shortly... -
Page 6: Measuring And Testing
Measuring and Testing General Instructions Automatic On/Off The voltage tester is switched on automatically as soon as a voltage value as of 24 V is applied. If “continuity testing” has been activated, the instrument switches automatically to “voltage testing”. The instrument automatically selects the measuring range which corresponds to the applied voltage value (see Characteristic Values). -
Page 7: Voltages Of Less Than 24 V
„–“ appears before the displayed value. Testing of Phase and Phase Sequence The METRAVOLT 12D+L is equipped with two tri- angular LED displays in order to perform phase sequence tests. These tests can be performed at a nominal voltage of at least 165 V (50 Hz) to earth. -
Page 8: Phase Test
4.3.1 Phase Test The phase conductor is determined by applying the test probe (+L1) to the conductor. If “POL” appears at the LCD panel, the conductor is live. 4.3.2 Testing of Phase Sequence The phase sequence between two phases in a grounded 3-phase system is determined as follows by applying both test probes and by clasping the handle bar of the display component:... -
