WARNING
WARNING
To avoid possible electric shock or personal injury, follow these
guidelines:
●
●
●
●
●
●
●
●
Do not use the meter if it is damaged. Before you use the meter,
inspect the case. Pay particular attention to the insulation
surrounding the connectors.
Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity. Replace damaged test leads
before you use the meter.
Do not use the meter if it operates abnormally. Protection may
be impaired. When in doubt, have the meter serviced.
Do not operate the meter where explosive gas, vapour, or dust
is present.
Do not apply more than the rated voltage, as marked on the
meter, between terminals or between any terminal and earth
ground.
Before use, verify the meter's operation by measuring a
known voltage.
When measuring current, turn off circuit power before connect-
ing the meter in the circuit. Remember to place the meter in
series with the circuit.
When servicing the meter, use only specified replacement parts.

Use caution when working with voltage above 30 V AC RMS,
42 V peak, or 60 V DC. Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the finger
guards on the probes.
Connect the common test lead before you connect the live test
lead. When you disconnect test leads, disconnect the live test
lead first.
Remove the test leads from the meter before you open the
battery cover or the case.
Do not operate the meter with the battery cover or portions of
the case removed or loosened.
To avoid false readings, which could lead to possible electric
shock or personal injury, replace the battery as soon as the low
battery indicator ( ) appears.
Do not use the meter in a manner not specified by this manual
or the safety features provided by the meter may be impaired.
Adhere to local and national safety codes. Individual protective
equipment must be used to prevent shock and arc blast injury
where hazardous live conductors are exposed.
To avoid electric shock and personal injury, do not touch any
naked conductor with hand or skin; and do not ground yourself
while using this meter.
Do not use the meter if the meter, a test lead or your hand is wet.
Remaining endangerment:
When an input terminal is connected to dangerous live potential,
it is to be noted that this potential can occur at all other terminals!

WARNING
●
CAT III - Measurement Category III is for measurements performed
in building installation. Examples are measurements on
distribution boards, circuit breakers, wiring, including cables,
bus-bars, junction boxes, switches, socket-outlets in the fixed
installation, and equipment for industrial use and some other
equipment, for example, stationary motors with permanent
connection to the fixed installation. Do not use the meter for
measurements within Measurement Categories IV.

WARNING
To avoid possible damage to the meter or to the equipment under
test, follow these guidelines:
●
●
●
●
Disconnect circuit power and discharge all capacitors thorough-
ly before testing resistance, diode, continuity or temperature.
Use the proper terminals, function and range for your measurements.
Before measuring current, check the meter's fuses and turn off
power to the circuit before connecting the meter to the circuit.
Before turning the rotary switch to change functions, disconnect
the test leads from the circuit under test.
Alternating current
Direct current
Both direct and alternating current
Caution, risk of danger. Refer to the operating manual before
use.
Caution, risk of electric shock.

CAUTION
This meter is a compact 3 1/2-digit digital multimeter designed to
measure DC and AC voltage, DC and AC current, resistance, continuity,
diode, battery and temperature. In addition, non-contact AC voltage
detection, live AC wire detection and illumination functions are also
provided. It features polarity indication, data hold, full-range overload
protection, and more. It is easy to operate and is a very useful test
tool.
