Single-Pole Phase Test; Voltage Test With Rcd Trip Test; Restistance Measurement (Only T140) - Fluke T100 Manual De Instrucciones

4.3 Single-Pole Phase Test

To carry out single-pole phase tests ouch the contact
electrode (11) and connect instrument test probes to un-
known contact.
The single-pole phase test starts at an AC voltage of ap-
prox. 100V (pole > 100V AC).
When using single-pole phase tests to determine exter-
nal conductors the display function may be impaired
under certain conditions (e.g. for insulating body protec-
tive equipment on insulation locations).
The single-pole phase testing is not appropriate to deter-
mine whether a line is live or not. For this purpose, the
double-pole voltage test is always required.
A signal sound indicates the phase.
The LED (5) is illuminated in the display.

4.4 Voltage Test with RCD Trip Test

During voltage tests in systems equipped with RCD circuit bre-
akers, a RCD switch can be tripped at a nominal residual cur-
rent of 10mA or 30mA by measuring the voltage between L and
PE.
The RCD trips.
To avoid RCD tripping a test has to be carried out between L and
N during approx. 5s. Immediately afterwards, voltage testing
between L and PE can be carried out without RCD tripping.

4.5 Restistance Measurement (only T140)

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
Ω
of 1
The resistance measurement is active for 20 seconds
after having pressed the button on the rear.
If during the resistance measurement a voltage is present
the instrument switch automatically to voltage measure-
ment.
