Fit the Appliance mains plug into the EUT outlet.
Connect the Earth Bond lead to the appliance metal
part. Press the green START key to begin the test. The
test will run for the duration set. To end the test before
the test time expires press the red STOP key.
Note: The PrimeTest display will show real time
measurements during an Earth Continuity
test.
The result shown at the end of the test can
be either the worst reading or the last
reading, depending on the Test Options
setting.
If set for “Worst” then the value is the peak
value measured during the test. This can be
used to detect momentary break in the earth
path e.g. damaged power cords or loose
mains plug connections.
If set for “Last” then it is the last value
measured. This can be useful JW
A Pass or Fail is determined by comparing
the peak value measured during the test with
the pre-set limit.
11.2 Insulation Resistance
Refer to Fig. 4
This test is applicable to Class I and Class
II equipment.
This test is used to verify that the mains supply pins
are adequately insulated from earth.
During this test, 250V or 500V D.C. is applied
between the earth pin and both the live and
neutral pins of the appliance mains supply
plug.
