Page 7: Measuring Line Voltage
When connected via the 5-pole CEE mains plug (23), indicator lamps L1, L2 and L3 (19) must light up. When connected via the earthing contact mains adapter (22), only indicator lamp L1 should light up. Mains polarity is tested for this type of connection, i.e. if lamp L1 does not light up, the polarity of the earthing contact plug must be reversed in the mains outlet. -

Page 12: Testing Devices In Accordance With Din Vde 0701-0702
Testing Devices in Accordance with DIN VDE 0701-0702 Always measure protective conductor resistance first for safety class I devices under test. Measurement of insulation resistance, equivalent leakage current and protective conductor current is not possible without a properly functioning protective conductor. This measurement is of special importance because a defective or reversed protective conductor may represent a hazard for the user! ... -
Page 13: Measuring Insulation Resistance
Attention The connector cable must be shaken back and forth, section by section over its entire length, during measurement (for permanently installed devices only insofar as the connector cable is accessible during repair, modification or testing). Unrealistic, continuously changing measured values indicate poor contact, a damaged protective conductor or a broken core in the probe cable (21) in the event that it has been excessively stressed! If brief or continuous interruption of the protective conductor occurs during the manual step of the continuity test, the limit value indicator at the... - Page 14 Limit Values per DIN VDE 0701-0702, Part 1: 2008 Device Type Limit Values Min.

Page 15: Measuring Protective Conductor Resistance
Measuring Protective Conductor Resistance 6.3.1 Equivalent Leakage Current In accordance with DIN VDE 0701-0702:2008, protective conductor resistance must be measured after the performance of the insulation resistance measurement. We recommend equivalent leakage current measurement. The limit value is: • 3.5 mA for protection class I devices whose exposed conductive parts are connected to the protective conductor. -
Page 16: Differential Current Measurement For Protection Class I Devices
6.3.2 Differential Current Measurement for Protection Class I Devices This test must be executed for all devices for which it is not possible to measure insulation resistance at all safety relevant parts (practically all DUTs with electrically actuated switches and relays), or where there is any doubt regarding measurement with insulation voltage, for example at electronic devices. -

Protective Conductor Resistance Measurement Perform test as described in section 6.1. The probe cable (21) is connected to the SI socket in the VL2 E test adapter. -
Page 20: Continuity Test With Extra-Low Voltage
The display can settle in within a range of 0 Ohm (if all cores are short-circuited) up to, for example, infinity (in the event of overload) if one core is interrupted. Due to good insulation assured by undamaged cables, a test value of 10 MOhm with a tolerance of 20% has been established for this rational test procedure. -
