PrimeTest 250+ Operating Instructions

• 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 CLI test key
to continue.
• 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 differential 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.
