HT EASYTEST - Mode

EASYTEST-COMBI519
EN - 46
6.6.4. Mode
The standard defines the tripping times for RCDs at nominal current. The
mode is used
to detect the tripping time at tripping current (which could also be lower than the nominal
current).
5.
Press the GO/STOP key on the instrument, the
START key on the remote switch probe or use the
AutoStart feature (see § 5.1.5). The instrument will
start the measurement.

CAUTION
If message “Measuring…” appears on the display, the instrument is
performing measurement. During this whole stage, do not disconnect the
test leads of the instrument from the mains.
6.
According to standard EN61008, the test for selective RCDs requires an interval of 60
seconds between the tests. The
mode is therefore unavailable for selective RCDs,
of each type.
7.
When the RCD trips and breaks the circuit, if the
tripping current and tripping time are within the limits
reported in 12.4, the instrument gives a double
acoustic signal, shows the “OK” message and
displays the screen to the side.
