The tester and all associated cables and leads
must be checked for signs of damage before
the equipment is operated.
Attention! During and Class I and Class II tests,
high voltage levels occur within the
PrimeTest 220.
Where safe operation of the tester is no longer possible,
it should be immediately shutdown and secured to
prevent accidental operation.
It must be assumed that safe operation is no longer
possible:
- if the instrument or the measuring leads show visible
signs of damage, or
- the tester does not function, or
- after long periods of storage under adverse
environmental conditions.
Important
- Do not touch the bare probe tips of the
measuring lead.
- Ensure the black measuring lead is plugged
into the corresponding black socket on the
PrimeTest 220
- Do not operate the PrimeTest 220 in an
explosive gas or dust environment.

5.0 General Information
5.1 Range overflow of the digital display 1 is
automatic and is indicated by the greater than
symbol >.
5.2 The button 6 allows a 30 second measurements
of and without the need to repeatedly press
the button. To activate the continuous test
mode the operator must press and hold the
button down then simultaneously press the
lock button down. Both buttons can then be
released in any order. The symbol will be
illuminated on the LCD display. The operator can
deactivate the mode by pressing either the or
buttons.
5.3 The PrimeTest 220 will automatically switch off
after a period of 5 minutes with no push button or
switch action. Where the mode is enabled the
automatic shutdown period is 3 minutes. When a
subsequent push button or switch action takes
place the instrument automatically switches itself
on again.
5.4 When the PrimeTest 220 is switched on from power
off position to another switch position, an on
load battery test occurs. The result of this
test determines the available battery capacity. A
healthy battery results in no battery symbol being
illuminated on the LCD display. A deteriorating
battery results in the symbol being illuminated in
the steady state. An unhealthy battery results in a
flashing symbol.
When the flashing symbol is displayed all test
and measurement functions are inhibited to
avoid endangering persons by recording false
measurements.
5.5 During the protective earth conductor current
and touch leakage test functions it is possible
that a RCD could be tripped due to the inadvertent
testing of a defective EUT.

8.0 Operation of test functions
8.1 Safety test, Class I
See figure 7
8.1.1 Select the Class I test function on the rotary
switch 10 . Ensure the IEC mains lead is
disconnected from the PrimeTest 220.
8.1.2 The LCD will display a probe signal to indicate that
an earth bond test lead is required. This test
function is selected when the equipment to be
tested is fitted with a protective earth conductor.
8.1.3 Plug the equipment under test (EUT) into the EUT
socket 11 on the front of the PrimeTest 220.
8.1.4 Plug the black test lead into the black socket 12 on
the PrimeTest 220.
8.1.5 Connect the other end of the black test lead to
exposed metalwork on the EUT.
8.1.6 To start a Class I safety test sequence, press the
button 9 .
8.1.7 The earth continuity resistance for the EUT is
measured at ± 200mA. The large display 2
indicates the highest digital earth resistance, Ω, the
small display 3 indicates a PASS/FAIL status. An
additional visual display of a ✓or ✗also indicates
the PASS/FAIL status.
8.1.8 Earth continuity resistance value is held on the LCD
display for a period of 1 second. A PASS or FAIL
indication will be shown, depending on value of the
displayed reading.
8.1.9 An earth continuity resistance that fails will
terminate the Class I PAT test, a PASS will
automatically sequence to the insulation resistance
test.

During an insulation resistance measurement a
high voltage is applied between the Live/Neutral
and Earth of the EUT. It should be noted that
this voltage can also be present on the bare
metalwork of the EUT.
8.1.10 The insulation resistance of the EUT is measured
over a period of 2 seconds. The large display 2
indicates digital insulation resistance, MΩ, the
small display 3 indicates a PASS/FAIL status. An
additional visual display of a ✓or a ✗also indicates
PASS/FAIL status.
8.1.11 The insulation resistance value will remain
displayed until another rotary switch action.
8.2 Protective Earth Conductor Current
See figure 4.
Attention - The Black 4mm test socket must not
be used whilst the PrimeTest 220 is performing
a leakage test. Electric Shock Danger.
Attention - before a protective earth conductor
current test is performed on a Class I EUT the
operator must ensure that the EUT has already
passed a Class I safety test.
Attention - An RCD may be triggered if the EUT
is defective.
Warning - it is important that the user verifies
that an appliance with moving parts (e.g. an
electric drill) is safely mounted to allow
movement without causing damage to
equipment or personnel.
8.2.1 Plug the supplied mains power lead into the mains
power socket 13 on the PrimeTest 220 .
8.2.2 Plug the other end of the supplied mains power
lead into a mains power socket.

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.

Attention - the protective earth conductor
current measurement can be affected by
exposure of the PrimeTest 220 to magnetic
fields or current being absorbed by the EUT
during differential leakage measurements.
Attention - where the input current waveform
displays a crest factor of 2 then a percentage
error of 2.2% is recorded on the PrimeTest 220
measured value.
8.3 Residual Current Device, RCD, Test
See figure 5
Attention - The Black 4mm test socket must not
be used whilst the PrimeTest 220 is performing
an RCD test. Electric Shock Danger!
8.3.1 Plug the supplied mains power lead into the mains
power socket 13 on the PrimeTest 220.
8.3.2 Plug the other end of the supplied mains power
lead into a mains power socket.
8.3.3 Select the RCD test function on the rotary switch
10 .
8.3.4 Switch on the mains power.
8.3.5 The PrimeTest 220 automatically 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 RCD 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.
