Safety Information
Read and understand this Instruction Manual completely
before using this instrument. Failure to observe the
warnings and cautions in this Instruction Manual may
result in injury or death, or damage to the instrument and
other equipment or property.
The following symbols may appear on the
instrument and in this Instruction Manual:
Warning
If this instrument is used in a manner not specied
in these instructions, the protection provided by the
instrument may be impaired.
Examine the instrument, probes and leads before use.
Do not use the instrument if it is wet or damaged, or if
you suspect it is not operating correctly.
• Always use the correct switch position and range for
measurements.
• Do not apply more than the rated voltage as marked
on the instrument between terminals, or between any
terminal and earth ground.
• To avoid incorrect readings that can lead to electric
shock, replace the battery as soon as low battery
indicator appears in the display.
• Use caution when measuring voltages above 30 Vac
rms or 60 Vdc. These voltages pose a shock hazard.
• Disconnect the circuit power and discharge all high-
voltage capacitors before making resistance, continuity,
diode, or capacitance measurements.
• Do not use the instrument in a Hazardous Area or
around explosive gasses or vapours.
• When using the instrument, test leads or probes, keep
your ngers behind the nger guards.
• Wear suitable Personal Protective Equipment when
working around or near Hazardous Live conductors
which could be accessible.
Caution
• When connecting the test leads to a circuit or device,
connect the black lead before the red lead and
disconnect the red lead before the black lead.
• If possible, do not work alone, so assistance can be
given if required.
• If this instrument is used in the vicinity of equipment
which generates electromagnetic interference, the
display may become unstable or the measurements
may be subject to large errors.
• Do not expose the instrument to extremes of
temperature or high humidity.
The internal sounder will operate continuously and
the LCD display will ash in two situations in the
Data Hold mode:
1. The instrument measures a signal different 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.
• For greater measurement accuracy of low-value
capacitance, subtract the residual capacitance of the
instrument and leads from the measured value.
• Under diode mode, the LCD will display “bad” when
measuring a diode which conducts in forward and
reverse bias.
• The instrument will default to capacitance mode when
no component is sensed by the Auto-sense mode.
• When using Auto-sense mode, do not attempt to
measure a faulty component, an unknown component,
or a component with mixed electrical characteristics
such as a resistor and a capacitor in parallel. The
instrument may display incorrectly.

Warning – For non-contact voltage sensing, do not
touch Hazardous Live conductors with the red or black
test-probe.
• For non-contact voltage sense, place the top of
the instrument body or the red test-probe near
the conductor.
• The buzzer will sound and the number of dashes
shown on the LCD will indicate the relative electric eld
strength. If there is no indication, a voltage may still be
present.
For calibration and repair contact RS Components - the
address is given at the end of these instructions.
Cleaning
Periodically wipe the case with a dry cloth and detergent.
Do not use abrasives or solvents.
Battery Replacement
