Always ensure that you have selected the correct test connection method in the test for the
probe connections made.
Ensure that the appliance mains switch is in the ON position.
During this test, 250V or 500V D.C. is applied between the two connections points. The 500V
D.C. potential will be present across the two probe tips during a Point to Point test.
13.2.1 Selecting a Test Type
In Manual PAT test mode, the Insulation Resistance test can be switched between a 250V EUT Insulation
test, 500V EUT Insulation test, 250V Point to Point Insulation test or 500V Point to Point Insulation test as
follows:
Select Insulation Resistance (2) and press the Tools key (F3). In the Test Type field, select the required test.
During automatic sequences, the test type will be as per the test type programmed in the test sequence.
In Manual Mode once the correct connections have been made for the selected test type press
the Start button, in automatic mode the test will proceed automatically. The test will continue until it times
out. If we wish to abort the current test press the Stop button. The measurement will be displayed in Mega
Ohms.
If a EUT fails the Insulation Resistance test then this may be because of internal filtering or a Metal Oxide
Varistor (MOV). Retry the test at 250V or substitute the Insulation Resistance test with a Protective
Conductor (class 1) or Touch Current test (class 2).
13.3 Protective Earth (PE) Conductor Current (Used on Class 1 Appliances)
Always test the earth continuity and insulation resistance before performing a PE
Conductor Current test.
Always check that an appliance with moving parts (e.g. an electric drill) is safely mounted
to avoid risk of damage to equipment or personnel.
Avoid prolonged, repeated use at full load (16A) and excessive test duration as this may
reduce the life of the unit.
Always ensure that appliance and leads, which include RCD protection, that the RCD is
reset at the beginning of the test. Failure to do so may result in incorrect measurements
being recorded.
This test is applicable on Class I Equipment.
The PrimeTest should be connected to a mains supply. The
Equipment Under Test (EUT) should be connected into the EUT
test socket.
In Manual Mode once the correct connections have been made
for the selected test type press the Start button, in Automatic
Mode the test will precede automatically.
