Safety Information
Read and understand this Instruction Manual completely before using this
instrument. Failure to observe the warnings and cautions in this Instruc-
tion Manual may result in injury or death, or damage to the
instrument and other equipment or property.
If this instrument is used in a manner not specified in these instructions,
the protection provided by the instrument may be impaired.
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 blown fuse with the correct type and rating as specified
in this Instruction Manual.
-Use caution when measuring voltages above 30 Vac rms or 60 Vdc.
These voltages pose a shock hazard.
-To avoid incorrect readings that can lead to electric shock, replace the
battery as soon as 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.

Caution
-Disconnect the test leads from the test points before changing the
position of the function rotary switch.
-Never connect the instrument to a source of voltage with the function
rotary switch in Ω/ ;/A//Hz position.
-If possible, do not work alone, so assistance can be given if required.
-Do not expose the instrument to extremes of temperature or high
humidity.
-Never set the instrument to the A function to measure the
voltage of a power supply circuit, as it may result in damage to the
instrument and the equipment under test.
Maintenance
Do not attempt to repair this Instrument. It contains no user-serviceable
parts. Repair or servicing should only be performed by qualified person-
nel. This instrument should be calibrated yearly, or more frequently if
used in harsh conditions or if it is suspected of being inaccurate.
For calibration and repair contact RS Components - the address is
given at the end of these instructions.
Cleaning
Periodically wipe the case with a damp cloth and detergent. Do not use
abrasives or solvents.

1. The VoltSense function will operate irrespective of the position of
the function rotary switch, including the OFF position.
2. Remove the test leads from the instrument as they are not used for
the VoltSense test.
3. Press and hold the VoltSense button. The LCD display will go blank,
a tone will sound and the red LED will illuminate momentarily to
confirm the instrument is operational.
4. Hold the Volt sense button down and move the instrument over the
area where detection is required. The buzzer will sound and the LED
will illuminate when a live conductor is detected. Release the
VoltSense button to return to normal operation.
