Warning
If the proving device or voltage source
exceeds the specified limits of the voltage
tester the voltage tester may be damaged
and the operator exposed to a shock hazard.
Always check the specification of the proving
device or the voltage magnitude of the
voltage source before proceeding with a
proving check.
During this verification emphasis should
also be placed upon the flexing of the
voltage tester's cable along its length, and
particularly at the entry points to the hand
held elements, to confirm that the cable has
not been fractured.
3.5 Removable Probe Tip Covers
The probes are fitted with removable probe
tip covers allowing the probes to comply with
GS38.
Where access to test points may require
extended probe tips, the probe tip covers
may be removed.
Where possible is advisable to keep these
shrouds fitted. If removed, great care must be
taken when using the voltage tester on CAT
III and CAT IV installations to avoid the risk of
shorting high energy circuits and arc flash.
3.6 Testing for the Presence of Hazardous
Live Voltage
Warning
Hold the voltage tester and test prod behind
the finger guards in a manner that will not
obscure the voltage indication LED's. Never
touch the exposed metal test prods or any
part of the voltage tester forward of the
finger guards while applied to hazardous
voltages.
If testing at locations with high background
noise levels, always determine whether the
buzzer is perceptible before relying solely on
the buzzer indication.
While taking all required safety precautions
connect both test probes to the UUT (Unit or
location under test).
The polarity and voltage level of any voltage
present will be indicated by the illumination of
the voltage tester LED's (see section 3.1).
