tip when the HPAT600 is performing an electrical test.
Where possible, use the crocodile clip provided to attach
the probe to the appliance.
if the 'Simulated load current Hi' message is displayed it
would be advisable to have the appliance investigated
by a suitably qualified technician.
3.14 Testing of 110V appliances
A TL157 PAT 110V Adaptor (available separately) is
required for testing 110V appliances (yellow BS4343
16A 110V plug).
Refer to the connection diagram below.
Ensure that the appliance is switched ON.
Undertake a test sequence as appropriate for the
appliance (See 3.4 to 3.9).
NOTE: The TL157 has a special configuration of
internal connections to enable the safe testing of Earth
Continuity and of Insulation Resistance for 110V
appliances.
However, for reasons of safety, the TL157 will not allow
a 110V appliance to draw any run current through the
mains socket (1). (This is to prevent inadvertent
connection of a 110V appliance to 240V mains).
For this reason, the test of a 110V appliance using the
TL157 will always result in a FAIL at the Fuse Check or
at Simulated Load test.
