GENERAL INSTRUCTIONS
The digital clamp meter has been designed according to IEC1010-1 and
IEC1010-2-032 concerning safety requirements for electrical measuring
instruments and hand-held current clamps with double insulation overvoltage
category 1000V CAT II 600V CAT III and pollution 2.
This meter complies with the requirements of the following European community
directives:
89 / 336 / EEC (Electromagnetic Compatibility) and 73 / 23 / EEC (Low Voltage)
as amended by 93 / 68 / EEC (CE Marking).
However, electrical noise or intense electromagnetic fields in the vicinity of the
equipment may disturb the measurement circuit.
Measuring instruments will also respond to unwanted signals that may be
present within the measurement circuit.
Users should exercise care and take appropriate precautions to avoid misleading.
1.1. Safety Precautions
• When using this multimeter, the user must observe all normal safety rules
concerning:
- Protection against the dangers of electric current.
- Protection of the multimeter against misuse.
• For your own safety, only use the test probes supplied with the multimeter provided.
• When the meter is delivered, check that it has not been damaged in transit.
If any part of the kit has been damaged, contact your dealer and DO NOT use
the meter.
• DO NOT touch unused terminals when meter is linked to a circuit.
• DO NOT measure voltage if the voltage on the terminals exceeds 600V above
earth ground.

6. MAINTENANCE
6.1 General Maintenance and Cleaning
To avoid electrical shock or damage to the multimeter, do not get
water inside the case. Remove the test leads and any input signals
before opening the case.
Cleaning the multimeter:
• Wipe the case with a soft damp (not wet) cloth and mild detergent.
• DO NOT use abrasive or solvents.
• Dirt or moisture in the terminals can affect readings.
Cleaning the terminals:
• Turn the meter off and remove all test leads.
• Shake out any dirt that may have gathered in the terminals.
• Soak a clean swab or cotton bud with a cleaning and oiling agent (such as WD-40).
• Work the swab/bud around in each terminal until you are happy there
are clean. The oiling agent insulates the terminals from moisture-related
contamination.
Before replacing the battery and fuses, disconnect test leads from
any circuit under test, turn the multimeter 'OFF' and remove test
leads from the input terminals.
To prevent damage to the meter or personal injury, always replace
the battery or fuse with specified rating.
6.2 Battery replacement
When the battery voltage drops below a usable operation range the symbol will
appear on the LCD display, this indicates that the battery supply will need
replacing. To do this you will need to do the following steps.
• Set the meter to 'OFF' state.
• Disconnect test leads from any inputs terminals.
• Use the appropriate screwdriver to unscrew the secured back cover. This will
expose the batteries.
• Replace the battery with 1.5V x3 new AAA batteries.
• Replace the battery cover and screw securely back into place.
• The multimeter should now be fully functional.

• Disconnect test leads from any inputs terminals.
• Use the appropriate screwdriver to unscrew the secured back cover and then
the battery cover.
• Replace the 2 back covers and screw securely back into place.
