Voltage Measurement; Circuit Continuity Test Under Voltage; Rcd Test; Measurement Of Resistance - Sonel P-4 Manual De Uso

To perform the RCD test:
 connect test probes to the tested circuit,
 press and simultaneously hold both buttons
. As a result:
 vibration motor vibrates after receiving
voltage (approx. 200 V),
 the indicator light
Pressing only one triggering button

3.6.1 Voltage measurement

Introducing low impedance into the tested circuit
reduces capacitive and inductive interferences.
3.6.2

Circuit continuity test under voltage

Activation of the vibration motor confirms the con-
tinuity of the tested circuit.

3.6.3 RCD test

The test involves forcing the differential current be-
tween L phase and PE line, and this current must
exceed the tripping current of the RCD.
3.7

Measurement of resistance

CAUTION!
The tested object must not be energized.

Press
select resistance measurement – the indicator
light

Apply the tips of test probes to the terminals of
the tested object.

Read the resistance value from the display.

The function is active only with efficient
batteries.

If the tips of test probes are open or the
measured value exceeds the measure-
ment range, the device displays value
OL.

If dangerous voltage is detected during
resistance measurement, the tester will
activate the indicator light of dangerous
voltage.

When operating in this mode, the Auto
OFF function of the tester is inactive.
