GENERAL INSTRUCTIONS
This multimeter has been designed according to IEC1010 standards for
electronic measuring instruments with an over-voltage category (CAT II 1000V,
CAT III 600V) and pollution level 2.
To get the best service from this instrument, read carefully this user manual and
respect the detailed safety precautions.
1.1. Precautionary safety measures
Preliminary
• 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 instrument.
Before use, check the probes are in good condition.
During use
• If the meter is used near noise generating equipment, be aware that the
display may become unstable or indicate large errors.
• DO NOT use the meter or test leads if they look damaged.
• Use the meter only as specified in this manual; otherwise, the protection
provided by the meter may be impaired.
• USE EXTREME CAUTION when working around bare conductors or bus bars.
• DO NOT operate the meter around explosive gas, vapour, or dust.
• BEFORE EACH MEASUREMENT make sure the main function dial is at the
correct position.
• When the range of the value to be measured is unknown, check that the range
initially set on the multimeter is at the correct test position.
• To avoid damage to the instrument, DO NOT exceed the maximum limits of the
input values.

voltages pose a shock hazard.
• When using the probes, keep your fingers behind the finger guards.
•
Before changing functions, disconnect the test leads from the circuit under
test.
• Disconnect circuits power & discharge all high-voltage capacitors before
testing resistance, continuity or diode.
• Before measuring current, turn power off to the circuit before connecting the
meter to the circuit.
• Change the battery when the symbol appears to avoid incorrect data.

Cleaning the multimeter:
• Wipe the case with a soft damp (not wet) cloth and mild detergent.
• DO NOT use abrasives 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.

appear on the LCD display, this indicates that the battery will need replacing. To do
this follow these steps.
• Set the meter to ‘OOFFFF’ state.
• Disconnect test leads from any input terminals.
• Use the appropriate screwdriver to unscrew the secured back cover. This will
expose the batteries.
• Replace the battery with 3 new 1.5V batteries (AAA).
• Replace the battery cover and screw securely back into place.
• The multimeter should new be fully functional.
