Electrical Tester / English
• Once voltage is applied to the measuring instrument,press the HOLD buttom,
the LCD and LEDs display shows the recoarded reading.
To delete the recorded value,press the HOLD button once again.the LCD and
LEDs display once again indicates the voltage currently being applied to the
probe tips.
5.3 Single-pole phase Test
• The single-pole phase test is only possible when batteries are installed and in
good condition.
• The single-pole phase test starts at an AC voltage of approx.100V (pole>100V AC).
• When using single-pole phase tests to determine external conductors the display
function may be impaired under certain conditions (e.g. for insulating body
protective equipment on insulation locations).
• The single-pole phase testing is not appropriate to determine whether a line is
live or not. For this purpose, the double-pole voltage test is always required.
• Connect both test probes with power source.
• A signal sound indicates the phase.
• The "
" LED is illuminated in the display.
5.4 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 illuminated.
5.5 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 imdedance
buttons (14)at the same time. If you have 10 mA or 30 mA RCDs between L
and PE in a 230 V system, it will trip.

• During load current,the low imdedance LED is the indication for the flowing load
current. This indication is not to be used for voltage test or measurement.
• If the two pushbuttons are not used, the RCDs will not trip, even in measurements
between L and PE.
5.6 Resistance Test
The Tester measures low ohm resistances between 1Ω and 1999Ω at a resolution
of 1Ω.
To do a resistance test:
• Do a Voltage test to make sure the UUT（unit under test） is not live.
• Push and hold the measurement point illumination button (15) for 2 seconds .
• Connect the two test probes with the UUT and read value on the display.
• Push and hold the measurement point illumination button (15) for 2 seconds
to turn the function off.
To save battery power the function automatically.
5.7 Rotary Field Indication
The voltage testers are equipped with a double-pole rotary field indicator.
The rotary phase indication is always active. The symbols "R"or "L" are always
displayed. However, the rotary direction can only be determined within a three-phase
system. 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 displayed.
"R" signifies that the supposed
phase L1 is the actual phase L1
and the supposed phase L2 is the
actual phase L2.
