 6. Measurement principle

This instrument has a constant current circuit, and drives leakage currents (I)
between LINE-NEUTRAL as illustrated in Fig.5 to activate RCDs, moreover,
can output and measure leakage currents flowing to the earth as shown in
Fig.6.

● Trip time measurement:
　　 Measure and displ ay the time be tween th e start of d riv ing leaka ge

currents (I) and trip of the RCD.

● Trip out cur
　　 Increase the leakage current gradually from the 40% of IΔn, the current

value when RCD trips is displayed.

Influence of the fluctuations in system voltages is less on this instrument due
to the incorporated constant current circuit.

7-1 Connection of Test Leads

Connect the test lead properly.

　● Connect the test lead M7128; red cord to the load of the Connector

block and black cord to the power supply.

　● When using the test lead with Alligator clip, connect the test lead M7128

(red) to the load of Connector block and M7129 to the power.

7-2 Setting of Measurement Range

Turn the Fun ction Sw itch and power on the in
appropriate Ranges.

Range construction: There are 4 Ranges on this instrument.

For trip time measurement :

x 5

Apply a current 5 times bigger than IΔn to measure RCD trip
time.

For trip time measurement :

x 1

Apply IΔn to measure RCD trip time.

For the test - rated residual non-operating current :

x 1/2

Apply a half of IΔn to confirm the RCD under test doesn't trip.

AUTO

Do not power on the instrument with it being connected to the live circuit.

For trip out current measurement :
Vary a testing current in the range of 40% ~ 110% of IΔn to
measure the trip
