Operating temp range 0°C to 40°C, without moisture
condensation.
Simple performance check
•With the test probe disconnected, a Class I test should
show an earth continuity test fail.
Maintenance
Clean only with a dry cloth; do not use solvents.
Before use, ensure unit is clean and dry; visually inspect
all leads, connectors, and case. Any damage or wear must
be rectified to preserve user safety.
Every 12 months the PAC3760 should be checked and
calibrated if required) by an authorised agent.
Service
Unless the unit is covered by the guarantee a charge will
be made for checking, repair, and calibration. Estimated
repair charges where appropriate) and freight charges will
be advised to the owner before work is commenced.
Warranty and repair
Units are covered by a 12 month parts and labour
warranty

PAC3760 Introd ction
The PAC3760 performs electrical safety checks on:
•Class I appliances CLI)
•Class II appliances CLII)
•IEC leads
•Extension leads
•Leads and appliances with MOVs
The PAC3760 is powered from a 240v 50Hz supply via
the fixed mains cord
An internal 10A fuse protects the PAC3760
•The mains supply voltage Phase-Earth PE),
Phase-Neutral PN) and Neutral-Earth NE), is
checked at power-on and before each leakage test.
A supply fault will display “HALT”and inhibit all tests
Test connections on the PAC3760 are:
•15A mains outlet socket on front panel
•4mm socket on top panel connects to test probe
•IEC inlet receptacle on top panel
•Ca tion: d ring ins lation tests 500v is applied
to the appliance nder test.
Do not to ch the appliance or the test probe.
Do not connect the test probe to voltages
greater than 30V.
User Interface
The LCD window displays test progress and results.
Tests are controlled using three push buttons.
•CLI, CLII, LKGE.
A tomated test ro tines (x6)
➀Class I appliance: earth continuity and insulation test
➁Class I appliance: earth continuity and power-on
leakage test. Also appliances with MOVs
➂Class II appliance: insulation test only
➃Class II appliance: power-on leakage test only
➄Class I lead: earth continuity, insulation and polarity
test
➅Class I lead: earth continuity test, power-on leakage
test. Also leads with MOVs
•Beware of moving or hot parts on the appliance
nder test d ring leakage (LKGE)
Load tests (within test ro tines)
The PAC3760 checks the appliance load before
progressing with tests.
LO-LOAD warning indicates that the appliance may be
switched off. The user can then switch on the appliance
and progress with the test automatically, or the user can
manually proceed with the test by pressing CLI or CLII
depending on the test in progress
HI-LOAD warning indicates that the appliance load may
be greater than 10A. The user can decide whether to
proceed with the test by pressing CLI or CLII depending
on the test in progress
LOAD-TOO-HI warning indicates that the appliance may
have a fault. The PAC3760 inhibits the test

APPLIANCE TESTS
Preparing an appliance for test
•Plug in the PAC3760 to a suitable mains supply
•Conduct a visual inspection of the appliance
•
Determine the Class of the appliance to be tested
•Plug the appliance into the PAC3760 front panel mains
socket and connect the test probe to a touchable metal
part on the appliance
•Choose ➀ ➁ for an insulation test or ➂ ➃ for a
‘power on’leakage test
➀Class I test with ins lation test
•Press the CL I button once
•
A pass is indicated by two ticks and “PASS”
•A fail is indicated by any cross: and “FAIL”
➁Class II test with ins lation test
•Press the CL II button once.
•A pass is indicated by one tick and “PASS”
•A fail is indicated by a cross: and “FAIL”
➂Class I test with ‘power-on’leakage test
•Press the CL I and ‘LKGE’ button together once
•Wait for a and . This indicates that power can
now be applied using the ‘LKGE’button
•Pressing the ‘LKGE’button causes and to appear
indicating that the front panel mains socket is now live.
Ensure that the appliance is powered
Beware of moving or hot parts on the appliance
•Power is applied for 30s unless the user presses the
‘LKGE’button and power is terminated
•Power off is indicated by only no )
•A pass is indicated by two ticks and “PASS”
•A fail is indicated by any cross: and “FAIL”
➃Class II test sing ‘power-on’leakage test
•Press the CL II and ‘LKGE’button together once
•Wait for the . This indicates that power can now be
applied using the ‘LKGE’button
•
Pressing the ‘LKGE’button causes and to appear
indicating that the front panel socket is now live.
Ensure that the appliance is powered
Beware of moving or hot parts on the appliance
•Power is applied for 30s unless the user presses the
‘LKGE’button and power is terminated
•

READ INSTRUCTIONS FOR USE
Due to the potential hazards associated with any electrical
circuit it is important that a user is fully familiar with
instructions covering the capabilities, applications and
operations of the instrument.
The user should ensure that all reasonable safety
procedures are followed and if any doubt exists should
seek advice before proceeding.
Front panel graphicsare provided to remind the user of
the six test arrangements.

!LEAD TESTS
Preparing a lead for test
•Plug in the PAC3760 to a suitable mains supply
•Conduct a visual inspection of the lead
•Connecting IEC Leads: plug into the front panel mains
socket and connect the IEC connector to the IEC inlet
receptacle on top panel
Ca tion, do not connect the IEC inlet receptacle
directly to mains power
•Connecting extension leads: plug into the front panel
mains socket and connect the IEC connector to the
IEC inlet receptacle on top panel using the extension
lead adapter accessory
•Choose
➄earth continuity, insulation and polarity test or
➅earth continuity and ‘power-on’leakage test
•NB. The PAC3760 automatically detects a “lead”
indicates a lead and includes polarity testing in
the sequence
➄Class I lead test with ins lation and polarity test
•Press the CL I button once
•A pass is indicated by two ticks and “PASS”
•A fail is indicated by any cross: and “FAIL”
➅Class I test with ‘power-on’leakage test
•Press the CL I and ‘LKGE’button together once
•Wait for a and . This indicates that power can
now be applied using the ‘LKGE’button
•Pressing the ‘LKGE’button causes and to appear
indicating that the front panel socket is now live
•Power is applied for 30s unless the user presses the

•Power off is indicated by only no )
•A pass is indicated by two ticks and “PASS”
•A fail is indicated by any cross: and “FAIL”
ADVANCED DIAGNOSIS OF A TEST FAIL
PAC3760 indicates the type of fail re when an
appliance or lead fails a test sequence.
•If an earth continuity test fails, there is a single left
hand cross and all other tests are prohibited
•If an insulation test fails there is a right hand cross
with RINS underneath
•If a power-on leakage test fails there is a right hand
cross with no ‘RINS’underneath)
•If a lead polarity test fails there is a right hand cross
and a further small icon at the bottom indicating
open circuit Live/Neutral, short circuit Live/Neutral, or
crossed Live/Neutral
•PN and NE indicates Live/Neutral reversed
•PE, PN and NE indicates a PE fault
