=> if U < U (see § 3.2), the instrument performs a non-tripping test. When the
FN L
the instrument:
- measures voltages U
- checks the probe resistance if the probe is connected,
- applies, for 1000ms, a current that depends on the nominal rating I
=> if, at the end of this test, the RCD has not tripped, the instrument then performs a tripping test and
measures the time to tripping in the "pulse" mode or the time to tripping and the tripping current in the
"sweep" mode. When the
- measures voltages U
- checks the probe resistance if the probe is connected,
- applies to the RCD to be tested, for a duration that depends on the test mode chosen and the
rating of the RCD to be tested, a current of which the value depends on the shape defined by
the user (see § 4.2.2.2).
Note: if the instrument is correctly connected and if the RCD tested is in conformity, it must trip before
the test current disappears. If not, the instrument automatically reverses the N and PE terminals and
repeats the tripping test (see § 4.2.2.6).
4.2.2.2 Preparation of the measurement
=> if necessary, in the SET-UP mode, adjust :
the threshold voltage U
the measurement current "I.ntP" according to the nominal current I
the type of compensation of the measuring cables (see § 3.3)
the alarm threshold Z
the number of measurements to take into account for the smoothing of the measurement (see
§ 3.2).
the value of U that will be used for the calculation of the short-circuit current (see § 4.2.1. 2)
REF
=> Set the switch to one of the RCD positions, according to the nominal rating of the RCD to be tested.
The "var." position is used for a finer adjustment of the test current or to adapt to non-standard
nominal ratings.
=> Perform a compensation of the measurement cables (see § 3.3).
