3.3 Proving a Test Lamp, Voltage Tester/Indicator, DMM etc.
Place one probe of the unit under test into the left hand socket of
the proving unit until it makes contact with the terminal. Place the
other probe into the right hand terminal of the proving unit and
gently press down.
On the PD440 and PD690 the high voltage indicator will illuminate.
On the PD430 and PD700 the low voltage indicator will illuminate
for 3 seconds, then the high voltage indicator.
Observe that the required indicators on the unit under test
illuminate, then withdraw the probe from the right hand terminal first,
and then the left.
Do not operate the proving unit for periods longer than 10 seconds.
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).
3.4 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 so as not
to operate the proving unit for longer than 10 seconds in any one
test episode.
4.4 Storage Conditions
The instrument should be kept in cool, dry conditions and not
subjected to shock, scratching or other damage, prolonged direct
harsh sunlight, extremes of temperature and in such a manner as
to preserve the working life of the unit. It is strongly advised that the
unit is not kept in a tool box where other tools may damage it.
