GENERAL DESCRIPTION
This multimeter is 4000 count, 3 3/4-digit digital multimeter. It can
be used to measure DC and AC voltage, DC and AC current,
resistance, capacitance, frequency, diode, temperature, continuity,
duty cycle, sound level, relative humidity and illumination. It can be
used as a test tool for environment and devices and is a high-perfor-
mance and versatile multimeter.
SAFETY INFORMATION
This meter has been designed according to IEC-61010
concerning electronic measuring instruments with a measurement
category (CAT III 300V) and pollution degree 2.
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.

WARNING

●
●
●
●
●
●
●
●
●
●
●
●
●
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 around explosive gas, vapour, or dust.
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 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,
When making connections, 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.
When in Relative Mode or in Data Hold mode, the symbol "REL"
or " " is displayed. Caution must be used because hazardous
voltage may be present.

WARNING

●
●
●
Do not use the meter in a manner not specified by this manual
or the safety features of the meter may be impaired.
Remaining endangerment:
When an input terminal is connected to dangerous live potential
it is to be noted that this potential at all other terminals can
occur!

WARNING
– Measurement Category III is for measurements
performed in the 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.

To avoid possible damage to the meter or to the equipment under
test, follow these guidelines:
●
●
●
●
●
Disconnect circuit power and discharge all capacitors before
testing resistance, diode, capacitor, temperature and continuity.
Use the proper terminals, function, and range for your measure-
ments.
Before measuring current or temperature, check the meter's
fuse and turn off the power to the circuit before connecting the
meter to the circuit.
Before rotating the range switch to change functions,
disconnect test leads from the circuit under test.
Remove test leads from the meter before opening the meter
case or the battery cover.
