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.
If this instrument is used in a manner not
specified in these instructions, the protec-
tion provided by the instrument may be
impaired.
The following symbols may appear on
the instrument and in this Instruction
Manual:

Equipment protected throughout by
double or reinforced insulation
Conforms to EU directives
Dispose of this equipment in
accordance with local regulations.
EApplication around and removal
from hazardous Live conductors is
permitted.
WARNING
-Examine the instrument and probes and
leads before use. Do not use the instru-
ment if it is wet or damaged, or if you
suspect it is not operating correctly.
-When using the instrument, test leads or
probes, keep your fingers behind the
finger guards.
-Remove the test lead from the instrument
before opening the battery cover or instru-
ment case.
-Always use the correct terminals, switch
position and range for measurements.

EN - 3
-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.
-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, continuity, or
diode 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/ ;/Aposition.
- 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.

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.
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.

Power On / Off
• When first turned on, the instrument
displays the remaining capacity of the
battery. Replace the battery when 0% is
shown or the low battery symbol “<”
remains visible in the display.
After a successful battery self-test, the
instrument will automatically select resis-
tance (Ω)/continuity mode.

Priority of function
The LCD display shows volt-
age mode, when the voltage at
the input terminals satisfies the
following conditions:
ACV:
Between 1.3V and 999.9V

Data Hold Beep Guard
The internal sounder will beep continuously
and the LCD display will flash if either of
the following two situations are met in Data
-hold mode :
1. The instrument measures a
characteristic different from the LCD
reading; e.g. a voltage reading is held
on the display and an attempt is made to
measure an AC current .
2. The measured signal is the same
characteristic as the LCD reading, but
is 50 counts or more greater than the
held LCD reading.
