Testing Appliances
For the vast majority of testing you can use the auto-test
mode. This is advantageous because you can just follow
the on screen instructions.
The manual test mode is designed for applications where
one particular test must be repeated several times in a
row and to quickly carry out a test.
Warnings

Before commencing any testing you are strongly
advised to make reference to the Electricity at
Work Regulations 1989 and any relevant
publications from the Health and Safety
Executive.
•
The appliance must be switched on for all tests.
•
When conducting tests do not touch the
appliance as some tests involve high voltages
and high currents.
•
The tests should only be performed by
competent persons who are familiar with the
requirements of the type of tests suitable for
portable appliances.
•
It is potentially hazardous for both user and
appliance should the wrong type of tests be
undertaken or if testing is carried out in an
incorrect sequence.
•
It is important that you fully understand the
various tests required and how they should be
performed.
•
The appliance must have passed the visual
inspection, the earth bond test (Class I), and the
insulation test (in this sequence) prior to any
other test. If any of these fail further testing must
be stopped and any faults must be rectified.
•
During the load/leakage test and the touch
current test, the appliance will be energized at
mains voltage. For this purpose, switch on the
appliance. Appliances driven by motors or
