Voltage Test with RCD Trip Test
(only T140 VDE)
1) Press Button on rear side -
measurement point light (10).
2) Measure between L and PE.
3) The RCD is tripping
The RCD could be so long tripped like the
measuring point lighting is active and L is
measured against PE. After a voltage test
wait approx.. 50 seconds to trip the RCD
again.
Restistance Test (only T140 /
T140 VDE)
Make sure that UUT is not live.
• Check that UUT is not live by carrying out a
double-pole voltage test.
• Connect both test probes with UUT. Press
Button on rear side - for measurement point
light (10) and read value on the display.
The resistance range is 1…1999 1 at a
resolution of 1 1.
The resistance test is active for 20 se-
conds after having pressed the button on
the rear.
If during the resistance measurement a
voltage is present the instrument switch
automatically to voltage measurement.
Continuity Test / Diode Test
Make sure that UUT is not live. Test volta-
ge polarity at handle test probe is positive
(+).
• Check that UUT is not live by carrying out a
double-pole voltage test.
• Connect both test probes with UUT. A signal
sound is audible for continuity and the LED
for continuity Rx/ 1 is illuminated.
