SECTION 1 –SAFETY INFORMATION
Safety Information
Understand and follow operating instructions carefully.
Use the instrument only as specified in this manual; otherwise, the
protection provided by the instrument may be impaired.
WARNING
Identifies hazardous conditions and actions that could cause
BODILY
HARM
or
DEATH
CAUTION
Identifies conditions and actions that could DAMAGE the instrument or
equipment under test
WARNING
- Examine the instrument and probes before use. Do not use the
instrument if it is wet or damaged
- When using test leads or probes, keep your fingers behind the finger
guards.
- Remove the test lead from the instrument before opening the battery
cover or instrument case.
- Always use the correct terminals, switch position and range for
measurements.
- Never attempt a voltage measurement with the test leads inserted into
the “A”input terminals.
- Verify the instrument is operating correctly by measuring a known
voltage before use. If in doubt, have the instrument serviced.
- Do not apply more than the rated voltage, as marked on the
instrument, between terminals or between any terminal and earth
ground.
- Do not attempt a current measurement when the open-circuit voltage
is above the fuse protection rating.
- Only replace a fuse with the correct type and rating as specified in this
instruction manual.
- Use caution when measuring voltages above 30 Vac rms, 42 Vac
peak or 60 Vdc. These voltages pose a shock hazard.
- To avoid false readings that can lead to electric shock, replace the
battery as soon as the low battery indicator appears in the display.
- Disconnect the circuit power and discharge all high-voltage capacitors
before making resistance, current, continuity, diode or capacitance
measurements.
- Do not use the instrument in a hazardous area or around explosive
gasses or vapours.
- Wear suitable personal protective equipment when working around or
near hazardous live conductors which could be accessible.
Risk of electric shock

AC measurement
Conforms to EU directives
Dispose of in accordance with local regulations.
CAUTION
• Disconnect the test leads from the test points before changing the
position of the function rotary switch.
• Never connect a source of voltage with the function rotary switch in
the
“Ω”, “ ”, “°C” , “mA”, or “A” position.
• Do not expose the instrument to extremes in temperature or high
humidity.
• Never set the instrument in the “Ω”, “ ”, “°C” , “mA”, or “A” position
to measure
the voltage of a circuit, this could result in damage the instrument and
the
equipment under test.
• If possible, do not work alone, so assistance can be given if required
The following symbols may appear on the instrument
and this instruction manual:
Unsafe Voltage
To alert you to the presence of a potentially hazardous voltage, when the
instrument detects a voltage
≧
30 V or a voltage overload (OL) in V, mV .
The symbol is displayed.
Maintenance
Do not attempt to repair this instrument. It contains no user-serviceable parts.
Repair or servicing should only be performed by qualified personnel. This
instrument should be calibrated yearly, or more frequently if used in harsh
conditions or if it is suspected of being inaccurate.
