Uc.....Contact voltage.
•
Disconnect the instrument from RCD under test.
Note: For safety reason, contact voltage is automatically measured before trip-out time is
measured. As the selective type of RCDs include integrator, it is necessary to wait some
time before the integrator sets to default. This is why the measuring process inserts a
pause 30 s for selective RCDs. The remaining time is displayed as count down from 30 to
1:
