During the sequence, the LEDs will indicate the actual output

voltage level as affected by load, not the no load output. Refer to the

graph of typical output voltage under various load conditions at the

rear of these instructions.

If none of the proving unit LED's illuminate when performing the

above tests check the condition of the proving unit batteries and

replace them if required (see section 4.1).

3.3 Test Lamp, Voltage Tester /Indicator Cables

During the above tests, emphasis should also be placed upon the

flexing of the UUT cable along its length, and particularly at the

entry points to the hand held elements, to confirm that the cable has

not fractured.

It may be necessary to perform this test a number of times as the

proving unit times cut out after 10s.

The CALCHECK feature may be used to check that a multifunction

tester, insulation tester or continuity tester is maintaining ongoing

accuracy between calibrations. There are two insulation test

resistance values, 0.5M

and 1M

Ω

Ω. There are also two continuity test

0.5

and 1

Ω

Ω.

resistance values,

One probe of the tester being checked should be placed on the

desired resistance value and the other probe should be placed on

the COM terminal, following the instruction manual for the tester

being used.

The CALCHECK feature is not designed to be used to check loop

testers, where the high test current will damage the proving device.
