Safety Information
To ensure safe operation and service of this
Clamp-multimeter, read these instructions
completely before use and comply with them
fully when using it.
Failure to observe these warnings can result
in severe injury or death.
- Avoid working alone so assistance can be
rendered.
- Do not use test leads or the Tester if they
look damaged.
- Do not use the Tester if the Tester is not
operating properly or if it is wet.
- Use the Tester only as specified in the
Instruction card or the protection by the
Tester might be impaired.
- Use extreme caution when working around
bare conductors or bus bar. Contact with
the conductor could result in electric shock.
- Do not use the Tester to measure voltages
in circuits that could be damaged by the
Tester’s low input impedance (approximate
4KΩ)
- Use caution with voltages above 30 V ac
rms, or 60 V dc. These voltages pose a
shock hazard.

Power On / Off
• The tester displays Battery Capacity
when powering up. Please replace the
battery when 0% is shown.
Caution
The Tester powers up in Ω / continuity
mode.

Fail of usage
Ready to use
• Do not measure while the tester powering
up, it will cause Self-Testing failure.
Caution
Do not use the tester when “FAIL” is shown.
Undiscovered failure could exist even “FAIL”
is not shown.

Caution
When connecting the test leads to the
circuit or device, connect the black lead
before the red lead ; when removing the
test leads, remove the red lead before the
black lead.

Note : to measure batteries with voltage less
than 2.1 Vdc the tester must be connected in
reverse polarity see illustration above.
• Input Impedance
≧
4K for input voltage up to 30V.
Impedance increases with input voltage to
approximate 375KΩ at 600V.
Warning
Do not apply more than 1000VDC / 600 VAC
between Tester terminal and earth ground.
Caution
If the tester is used in the vicinity of equipment which generates electromagnetic
interference, the display may become
unstable or the measurements show may be
subject to large errors.

Data Hold Beep Guard
In Data Hold mode, the LCD will flash and
the internal speaker will sound continuously
in the following two situations:
1. The tester measures a different signal to
that shown on the LCD.
2. The measured signal is the same units as
the LCD reading, but different by more
than 50 counts to the LCD reading.

Battery Replacement
Caution :
The calibration seal can only be punctured
by certified distributor for annual calibration
otherwise the meter’s performance can not
be warranted.

Maintenance
Do not attempt to repair this tester.
It contains no user-serviceable parts.
Repair or serving should only be performed
by qualified personnel.
Cleaning
Periodically wipe the case with a dry cloth
and detergent do not use abrasives or
solvents.
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.
