Precautions - Martindale Electric VT12 Instruction Manual

1.2 Precautions

This product has been designed with your
safety in mind, but please pay attention to
the following warnings and cautions before
use.
Warnings
In order to avoid the danger of electrical
shock, it is important that proper safety
measures are taken when working with
voltages exceeding the extra low voltage
(ELV) limit of 50V AC RMS or 120V DC.
Where applicable other safety measures
such as the use of protective gloves,
goggles etc. should be employed.
The voltage tester must only be used by a
skilled and competent person who is familiar
with the relevant regulations, the safety risks
involved and the consequent normal safe
working practices.
Before each use the voltage tester should
be examined for damage, cracks, cuts or
scratches to the housing, cable and prods.
The cable has black outer and contrasting
inner insulation, to allow damage to the
cable to be easily identified. If there is any
doubt the voltage tester should not be
used.
Make sure the voltage tester is dry, clean
and free from dust, grease and moisture
while in use to avoid the danger from electric
shock due to surface leakage.
Before and after each use, the voltage tester
must be proven using a suitable proving
device or a known good voltage source. Do
not use the voltage tester if any expected
LED's fail to illuminate correctly during
proving.
Testing for a voltage that exceeds the
specified limits of the voltage tester may
damage the voltage tester and may expose
the operator to a shock hazard. Always
check the voltage tester's specified limits
before use.
The voltage tester must only be used in low
voltage systems of CAT IV up to 300V, of
CAT III and CAT II up to 690V, and within the
operating temperature and humidity range
specified.
