CONTINUITY TEST
The continuity test test is only possible when batteries are installed and in good
condition. A signal sound is audible for continuity and the LED for continuity LED
[6] is illumitated.
VOLTAGE TEST WITH SWITCHED LOAD, RCD TRIP TEST
· During voltage tests, you can decrease the interference voltages from inductive
or capacitive coupling by loading the UUT with a lower impedance than the
tester has in normal mode. In systems with RCD circuit breakers, you can trip
an RCD switch with the same low impedance as when you measure voltage
between L and PE*.
· To do an RCD trip test during voltage measurement, push the two low imped-
ance buttons [13] at the same time. If you have 10mA or 30mA RCDs between L
and PE* in a 230V system, it will trip.
· During load current, the low impedance LED is the indication for the flowing
load current. This indication is not to be used for voltage test of measurement.
· If the two pushbuttons are not used, the RCDs will not trip, even in measure-
ments between L and PE*
(* Protective earth: grounding)
ROTARY FIELD INDICATION
The voltage testers are equipped with a double-pole rotary field indicator. The
rotary phase indication is always active. Te symbols “R” or “L” are always displayed.
However, the rotary direction can only be determined within a three-phase sys-
tem. Here, the instrument indicates the voltage between two external conductors.
Connect the instrument test probe with the supposed phase L2 and the handle
test probe with the supposed phase L1. The voltage and the rotary field direction
are dispayed.
· “R” signifies that the supposed phase L1 is the actual phase L1 and the sup-
posed phase L2 is the actual phase L2.
“L” signifies that the supposed phase L1 is the actual phase L2 and the supposed
phase L2 is the actual phase L1.
When re-testing with exchanged test probes the opposite symbol has to be allu-
minated.
MEASUREMENT POINT ILLUMINATION
This voltage tester are equipped with a measurement point illumination feature.
Thus, working under bad lighting conditions (e.g. division switch cabinets) is
made easier. Press the button for measurement point illumination [14] to activate
the LED flashlight.
