4.3.1.2. Mode "MAN x1, x2, x5"
4. Press the
START/STOP key once. The instrument carries out the
test injecting a current in phase with positive half wave of the
voltage indicated on
display by 0°.
Press the START/STOP key twice. The instrument carries out the
test injecting a current in phase with negative half wave of the
voltage indicated on
display by 180°.
NOTE: ”Man 5 I
∆n
” and “AUTO” test modes aren’t available for RCD type A 500mA.
When the RCD trips if the tripping time
is within the limits reported in table, the
instrument emits a
double sound
signal indicating the positive
outcome of the test and displays the
screen alongside.

SAVING:
The test can be stored pressing the
SAVE key twice
(according to paragraph 5.1).
4.3.1.3. Mode
"AUTO"
4. Press
the
START/STOP key: The instrument carries out the following
six tests with different values of rated current:
1/2I
∆n
at 0° (the RCD shall not trip).
1/2I ∆n at 180° (the RCD shall not trip).
I
∆n
at 0° (the RCD trips, blinking rcd, switch it on again).
I ∆n at 180° (the RCD trips, blinking
rcd, switch it on again).
5I ∆n at 0° (the RCD trips, blinking
rcd, switch it on again).
5I
∆n
at 180° (the RCD trips, end of the test).
In AUTO mode for each positive result (tripping time within the limits
see table) of a single test the following are displayed:
OK test
passed.
Blinking rcd switch the RCD on again (if the RCD is not switched on
again the instrument does not proceed with the test).
The test ends if all values of test tripping times fall within the limits
reported in table, or at the first value out of limits.
RCD tripping time
OK: indicates that the RCD passed the test.
It indicates if the test was carried out with current
phase 0° or 180° with respect to the voltage. Limit set for the
contact voltage.
