Operating Instructions
Primetest 220
12
8.2.3 Plug the equipment under test (EUT) into the EUT
socket 11 on the front of the PrimeTest 220
8.2.4 Select the protective earth conductor current test
function, on the rotary switch 10 .
8.2.5 When the button 9 is pressed the PrimeTest
220 checks the wiring of the power socket being
used. If the line potentials are correct then the LCD
will display the symbols PE and PN in the steady
state. Where a fault exists, then the appropriate
symbol will flash (see Appendix 1) along with the
symbol being displayed in the steady state.
A fault condition will inhibit the differential leakage
current test.
If a power test is selected but the mains supply
has not been connected to the PrimeTest 220
then PE and PN symbols will flash and the test
is inhibited.
8.2.6 To start the differential leakage test, press the
button 9 . Mains power is applied to the EUT
for a period of 2 seconds.
8.2.7 Where a longer protective earth conductor current
test is required the operator must press and hold
the button down, them simultaneously
press the lock button down. Mains power is
applied to the EUT for a period of up to 30
seconds. The operator can deactivate the mode
and end the test by pressing the button.
8.2.8 The large digital display 2 indicates the differential
leakage current, in mA, the small digital display 3
indicates a PASS/FAIL status. An additional visual
display of a ✓ or ✗ also indicate the PASS/FAIL
status.
8.2.9 The differential leakage current will remain
displayed until another rotary switch or push button
action.
