Safety Information
For safe operation of this clamp-multimeter,
read these instructions completely before
you use it and comply with them fully.
Failure to observe these warnings can
result in severe injury or death.
- If possible, do not work alone, so
assistance can be given if required.
- Do not use the clamp-multimeter or
test-leads if they are damaged.
- Do not use the clamp-multimeter if it is not
operating correctly, or if it is wet.
- Use the clamp-multimeter only as
specified in these Operating Instructions,
or the protection provided by it may be
impaired.
- Use extreme caution and wear Personal
Protective Equipment when taking
measurements where Hazardous Live
parts could be Accessible.
- Use caution when measuring or working
near voltages above 30 V ac rms, or
60 V dc. These voltages may cause a
shock.
- Do not allow fingers to protrude beyond
the Tactile Barrier when fitting or
removing the instrument from around a
Hazardous Live conductor, as this may
cause a shock.
Symbols as marked on the Clampmultimeter and instructions
Risk of electric shock
Refer to operating instructions.

Caution
If the clamp-multimeter is used in the vicinity
of equipment which generates electromagnetic interference, the display may become
unstable or the measurements shown may
be subject to large errors.
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
electrical 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.
Maintenance
Do not attempt to repair the clampmultimeter. It contains no user-serviceable
parts.
Contact RS Components fo r re pair,
servicing or calibration of this clampmultimeter. The address is given at the
end of these instructions.
Cleaning
To clean the clamp-multimeter, use a
damp cloth moistened with a weak
detergent solution. Do not use abrasives
or solvents.
