Appliance Visual Checks
Before carrying out PAT32 electrical tests, the appliance
and its accessories must be given a visual inspection to
identify any physical faults that may not be revealed by
electrical testing.
Visually examine and check the condition of the:-
• Supply plug
• Plug fuse type and rating (if applicable)
• Mains cord
• Cord connection grommet (if applicable)
• Mains On /Off switch
• Auxiliary switches
• Conducting / Insulated parts of the outer case
• Removable covers which must be in place.
Any significant faults or defects must be rectified before
proceeding with the PAT 32 electrical tests.
Auto Nulling and Self check
When not being operated, PAT 32 will periodically carry
out measurement nulling. The word is displayed.
Press any Test switch to override this function.
A self check function is also continuously performed on
the selected test range.
If testing is interrupted, for instance due to the appliance
not being switched On, or the mains fuse being ruptured,
testing must be repeated from the start of the test
sequence in the corrected condition. i.e. with a sound
fuse and with the appliance switched On.
