After a further period of 6 seconds the LCD display will switch off and the READY indi-
cator will illuminate showing that the PAC1500Xi is ready to commence a further test.
Until the READY indicator lights further depressions of the TEST button will not initiate
tests. The TEST button must be released and depressed to initiate a test. Continual
depression of the switch will not result in a continuous sequence of tests.

Results
The indicated resistance should typically be in excess of;

Class 1 .... 2M

Ω

Class 2 .... 7M

Ω

Technical
The PAC1500Xi applies a nominal 500V DC between the earth pin of the top plate 13A
socket and the Phase & Neutral pins which are connected together during the test for a
period of 6 seconds (or until the TEST button is released whichever is the shorter).
The additional earth connection available on a test lead is to test all exposed metal
work on the appliance ensuring that minimum insulation levels are held at all points on
the appliance.

TEST RESULTS
Each appliance tested should exhibit the following test results;

Any other test results suggests a defective appliance.

FUSE TEST

General
The objective of this test is to confirm the integrity of the appliance fuse.

Connection
The appliance should be plugged into the PAC1500Xi front panel 13A or BS4343 socket
The appliance under test must be switched on.
The PAC1500Xi should be switched to fuse test.

Procedure
The test is initiated by pressing the TEST push-button. This button must remain
pressed throughout the duration of the test. If for any reason the test button is released
the test will be aborted.
The FUSE OK indicator will illuminate to confirm the integrity of the appliance fuse.

Technical
A low current limited AC voltage of 9 volts is applied to the appliance and the current
flow detected and indicated. The circuit will indicate for circuit resistance of

≤

Ω

Ohms i.e. appliances

≥

50W.

Certain appliances that contain semiconductors within the power circuit may not
give a correct indication of fuse integrity.
