4.2. MΩ: INSULATION RESISTANCE WITH TEST VOLTAGE OF 50V, 100V,

250V, 500V OR 1000V

The measurement is effected according to EN 61557-2 and VDE 0413 part 1.

CAUTION

Before effecting the insulation test make sure that the circuit under test is not

energized and all the relative loads are disconnected.

Turn the switch on MΩ position.

Switch on the instrument.

The key FUNC permits to select one of the following measuring modes

(which can be shown cyclically when pressing the key):

 Mode MAN (minimum test time of 10 seconds or set by the pressing

duration on the START/STOP key). Recommended test.

 Mode TIMER (test duration depending on the selected interval (from 10

to 999 seconds). This test can be effected in case a minimum measuring

time is required.

4.2.1. Procedure to measure insulation resistance in any modes

1. Select the desired mode by means of the FUNC key.

2. Connect the black and blue cables to the instrument input terminals B1 and B4

respectively.

B2 B3 B4B1

Insulation between phase and earth in an electrical

installation using untied cables.

B2 B3 B4B1

Insulation between phase and earth in an

electrical installation using the shuko cable.

3. If the cables supplied with the instrument are not long enough for the measurement you can

extend the blue cable.

4. Connect the instrument terminals to the object which is to be submitted to the insulation

test after disconnecting the circuit under test and all the relative loads (see

previous picture).

5. By means of U

∆n

select the test voltage suitable for the type of test

to be carried out (see table). The values to be selected are 50, 100,

250, 500, 1000V DC
