incorporates voltage warning circuits in case of accidental
connection to an AC voltage. On no account should the
product be used to measure voltage. Voltages should be
measured with a dedicated voltage measuring instrument
and it is recommended that fused test leads are always
used for personal safety when measuring such voltages
especially on high energy circuits.
Note: This product is supplied with ACC020 unfused leads.
Thes can be converted to fully fused types by attaching the
optional ACC040 fused module.
1.13 Users of this equipment and or their employers are
reminded that Health and Safety Legislation require them
to carry out valid risk assessments of all electrical work so
as to identify potential sources of electrical danger and risk
of electrical injury such as from inadvertent short circuit.
Where the assessments show that the risk is significant
then the use of fused test leads constructed in accordance
with the HSE guidance note GS38 Electrical Test
Equipment for use by Electricians should be used.
1.14 Always keep your hands and fingers behind finger guards
on test leads used with this instrument. For safety reasons
always use the accessories approved by Kewtech. The use
of other accessories is prohibited as they may not have the
same safety features built in.
