!Safety Information
Warning (Identify hazardous conditions and actions
that could cause BODILY HARM or DEATH)
• General (Including the request from EN61010-1)
• If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the
equipment may be impaired.
• Always use proper terminals, switch position, and range
for measurements.
• To reduce the risk of fire or electric shock, do not use this
product around explosive gas or vapor.
• Verify the Meter operation by measuring a known
voltage. If in doubt, have the Meter serviced.
• Do not apply more than the rated voltage, as marked on
Meter, between terminals or between any terminal and
earth ground.
• To avoid false readings that can lead to electric shock
and injury, replace battery as soon as low battery
indicator appears.
• Avoid working alone so assistance can be rendered.
• Do not use the Tester if the Tester is not operating
properly or if it is wet.
• Individual protective device must be used if hazardous
live parts in the installation where the measurement is to
be carried out could be accessible.
• When using test leads or probes, keep your fingers
behind the finger guards.
• Do not use test leads or the Tester if they look damaged.
• Remove test lead from Meter before opening the battery
door or Meter case.
• Only replace the blown fuse with the proper rating as
specified in this manual.
• Do not attempt a current measurement when the open
voltage is above the fuse protection rating. Suspected
open voltage can be checked with voltage function.
67 EN
1
• Never attempt a voltage measurement with the test lead
inserted into the A input terminal
• Use caution with voltages above 30 Vac rms, 42 Vac
peak, or 60 Vdc. These voltages pose a shock hazard.
• DO NOT USE the test leads above maximum ratings of
CAT. environment, voltage and current, that are indicated
on the probe and the probe tip guard cap.
• DO NOT USE the test leads without the probe tip guard
cap in CAT III and CAT IV environments.
• Probe assemblies to be used for MAINS measurements
shall be RATED as appropriate for MEASUREMENT
CATEGORY III or IV according to IEC 61010-031 and
shall have a voltage RATING of at least the voltage of
the circuit to be measured.
• Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes.
Caution (Identify conditions and actions that could
cause DAMAGE the meter or equipment under test)
General
• Disconnect the test leads from the test points before
changing the position of the function rotary switch.
• Never voltage with the function rotary switch in
resistance, diode, continuity
• Do not expose Meter to extremes in temperature of high
humidity.

counts LCD readout with 65 segments analog bar
graph, auto polarity, decimal point, , HOLD, DC ,
AC , ,RANGE, and Unit annunciators.
2. Rotary Switch — Selects the desired function and
range.
3. COM Input Terminal — Ground input connector.
4. V Ω Input Terminal — Positive input connector for
Volts, Ohms and Diode measurements.
5. μA mA Input Terminal — Positive input connector for
current and measurements. (up to 300mA).
6. A Input Terminal — Positive input connector for current
measurements, up to 10A.
7. Function Switch (Blue) — Press the switch to
measure AC voltage or DC voltage in the Voltage mode
or to measure AC current or DC current in the current
mode, or to measure continuity or diode check in /
mode.
8. Reset Switch — The meter can be turned back on by
pushing "RESET" key switch.
9. Hold Switch — This switch is used to hold measured
values for all functions. When pressed the "HOLD"
annunciator is displayed. Conversions are made but the

3-1 Preparation and Caution before Measurement
1. Before measurement, warm up for at least 30 seconds.
2. When the rotary function selector is changed during
measurement, be sure to do so only after removing the
test leads from the equipment.
3. If the equipment is used near noise generating
equipment, be aware that the display may become
unstable or indicate large errors.
4. Maximum rated voltage to earth for voltage and
current measurements terminals is 600V AC/DC CAT II.
3-2 Voltage Measurements
1. Connect the red test lead to the " V Ω " input terminal
and the black test lead to the "COM" terminal.
2. Set the rotary function switch to the ACV or DCV
position.
3. Connect the test leads to the device to be measured.
4. When the input is over-ranged the most significant digit
of LCD display flashes and the three last significant
digits are set to zero.
5. " Warning : Do not exceed 600Vd.c. or 600Va.c.
limits stated in the specification".
Warning
TO AVOID ELECTRIC SHOCK HAZARD, OR DAMAGE
TO THE METER, DO NOT ATTEMPT TO MEASURE
VOLTAGES THAT MIGHT EXCEED 600 VOLTS d.c. OR
600 VOLTS a.c.. DO NOT APPLY MORE THAN 600V
d.c. OR 600V a.c. RMS BETWEEN THE COMMON
INPUT TERMINAL AND EARTH GROUND.
3-3 Resistance Measurement
1. Connect the red test lead to the " V Ω " terminal and
the black test lead to the "COM" terminal.
2. Set the rotary function switch to the "Ω" position to
measure resistance.
