TEST EQUIPMENT RISK ASSESSMENT
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 electri-
cal work so as to identify potential
sources of electrical danger and risk of
electrical injury such as from inadvertent
short circuits. Where the assessments
show that the risk is significant then the
use of fused test leads constructed in
accordance with HSE guidance note
GS38 “ Electrical Test Equipment for
use by Electricians” should be used.
Symbols as marked on the
instrument and instructions.
Risk of electric shock
Refer to operating instructions.

EMay be used on uninsulated
Conductors.
Warning
Do not apply more than 600V rms
ac between the instrument terminals
and earth ground .
-Avoid working alone, so assistance can
be rendered if required.
- Do not use test leads or the instrument
if they look damaged.
- Do not use the instrument if it is not
operating properly or if it is wet.
- Use the instrument only as specified in
these Operating Instructions, or the
protection provided by the instrument
may be impaired.
- Use extreme caution when working
around bare conductors or bus bar.
Contact with a hazardous live conduc-
tor could result in electric shock.
-Wear appropriate Personal Protective
Equipment if working where hazardous
live parts are accessible.
-Do not hold the instrument beyond the
Tactile Barrier, or allow fingers to pro-
trude past it.
The purpose of the barrier is to provide
adequate clearance between the op-
erator and a hazardous live conductor.
- Use caution with voltages above 30 V
ac rms, or 60 V dc. These voltages
pose a shock hazard.
Warning
Do not apply more than 600V rms
dc between the instrument terminals
and earth ground .
