Caution: Refer to accompanying notes
Equipment complies with relevant EU Directive
• Safety Warnings and Precautions must be read and understood before the instrument is used. They must be observed during use.
• For safety, PAT4 must be properly earthed. Only use a supply socket that has a protective earth contact. If there is any doubt as to
the effectiveness of the supply socket earth, connect a known good earth to the earthing point on the PAT4 front panel.
• Test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation. The flash test probe must
be held behind the handguard, and only be connected to the PAT4 for the duration of the test.
• For safety, tests are performed in the correct order. If an asset (appliance) fails a test, PAT4 will fail the asset and exit the test sequence.
The fault causing the failure must be corrected before the appliance is re-tested.
• During testing, ensure that no hazard will exist if the asset operates as a result of normal running, or of a fault condition.
• Assets should not be routinely flash tested.
• Where assets have to be flash tested, see 'Flash Testing – Warnings' on page 11.
When performing an Insulation test the asset must not be touched.
•
• Only perform an Operation test after an Earth Bond Test (Class 1 only) and Insulation Test (Class 1 or Class 2) have been verified.
• The instrument should not be used if any part of it is damaged.
• Replacement fuses must be of the correct type and rating. See 'Fuses' section.
