• Check that the appliance power switch is in the
ON position. The test will automatically proceed
if the appliance power switch is placed in the
ON position.
• If the LO LOAd enunciator remains on the
display, the load presented by the appliance
may be too small for the PrimeTest 250+
to detect. In this case, press the CLII test key
to continue.
• The PrimeTest 250+ will perform an Insulation
test. If the Insulation Resistance is greater
than the factory set limit a tick is placed next to
the Riso enunciator. If the Insulation Resistance
is less than the set limit a cross is placed
next to the Riso enunciator, the FAIL enunciator
is displayed and the test sequence is halted.
Note: If a mains supply is detected, the
PrimeTest
250+ will perform a touch
leakage test.
If the PrimeTest 250+ does not detect
a mains supply then the PrimeTest 250+
will perform a substitute leakage test.
• If a Substitute Leakage test is performed then
the PrimeTest 250+ will start the test without
the need for user intervention. If the Substitute
Leakage is less than the factory set limit a tick
is placed next to the Iea enunciator.
