1. Set the limit value of contact voltage (see § 4.2.10)

2. Select position RCD

3. Press key MODE/MXMNPK and select one of the following options:

 Mode AUTO RCD T  Measurement of the RCD’s tripping time in automatic

sequence with test currents In, 5xIn, ½In and polarity 0° and 180°. See Table 1

in § 7.1 to identify possible combinations

 Mode RCD T ½In  Measurement of manual tripping time with test current ½In

and polarity 0° and 180°. See Table 1 in § 7.1 to identify possible combinations

 Mode RCD T In  Measurement of manual tripping time with test current In and

polarity 0° and 180°

 Mode RCD T 5xIn  Measurement of manual tripping time with test current 5xIn

and polarity 0° and 180. See Table 1 in § 7.1 to identify possible combinations

 Mode RCD  Measurement of tripping current with increasing “ramp” method

and polarity 0° and 180° (only AC and A RCDs with 30mA).

4. Press key RCDIN/ to set the rated tripping time of the RCD among the options:

30mA, 100mA, 300mA. See table in § to identify possible combinations

5. Press and hold (>2s) key RCDIN/ to set the type of RCD among the options:

(type AC) and (type A). See table in § to identify possible combinations

6. In case the cable with Shuko plug is used, insert the red conductor into input terminal

V  L and the green conductor into input terminal COM/E/N and connect the

instrument to the system to be tested (see Fig. 29). The presence of phase-to-earth

voltage is shown in the bargraph

7. In case measuring leads are used, insert the red conductor into input terminal V  L

and the black conductor into input terminal COM/E/N and connect the instrument to the

system to be tested (see Fig. 30 or Fig. 31). The presence of phase-to-earth voltage is

shown in the bargraph

8. Press key GO/HOLD to activate the test with polarity 0°. Press again GO/HOLD key

with symbol flashes on the display to activate polarity 180°. The screens shown in

Fig. 19, Fig. 20 and Fig. 21 may appear on the display for a few seconds to signal

anomalous conditions in which the instrument does not carry out the test.

9. In case no anomalous conditions are present, the instrument carries out the test and

symbol flashes on the display. During and at the end of the test, the following

screens appear on the display:

Tripping time in automatic mode (AUTO) (6 tests in a sequence)
