This meter is designed for indoor use at temperatures between 0°C to 40°C and
•
altitudes up to 2,000m.
T o ensure that the meter is used safely , follow all safety and operating instructions in
•
this operation manual. If the meter is not used as described in this operation manual,
the safety features of this meter might be impaired.
Do not use the meter if the meter or test leads look damaged ,or if you suspect that
•
the meter is not operating properly.
When using the instrument, keep your fi ngers behind the fi nger guards on the plastic
•
casing and probes.
Disconnect the live test lead before disconnecting the common test lead.
•
Make sure power is off before cutting, desoldering, or breaking the circuit wires. Small
•
amounts of current can be dangerous.
Do not apply more than 600 VDC or 600V AC rms between a terminal and ground.
•
To avoid electrical shock, use CAUTION when working above 60V DC or 25V AC
•
rms. Such voltages pose a shock hazard.
Never make measurements with the battery cover off.
•
To avoid electrical shock or damage to the meter, do not exceed the input limits.

4.2 Measurement Procedures
CAUTION: Maximum Input Voltage is 600V rms,do not exceed
this rating to avoid personal injuries or damage to
the instrument. The range FUNCTION/RANGE
switch should be set to the range you want to test
before the operation.
CAUTION: Always ensure that the correct terminals are used
for the type of measurement to be made. Avoid
making connections to “live” circuits whenever
possible.When making current measurements ensure that the circuit is not “live” before opening it in
order to connect the test leads.

Connect the black test lead to the “COM” socket and red test lead
•
to the “V mA” socket.
Set the FUNCTION/RANGE switch to the desired range in the
•
“V ” function. If the voltage range is not known beforehand, set
the switch to the highest range and work down as needed.
Connect the test leads across the source or load under
•
measurement.
The measurement and polarity will be shown the LCD Display
•
when the probe are connected.
4.2.2 AC Voltage measurement
Connect the black test lead to the “COM” socket and red test lead
•
to the “V Ω mA” socket.
Set the FUNCTION/RANGE switch to the desired range in the
•
“V ” function. If the voltage range is not known beforehand, set
the switch to the highest range and work down as needed.
Connect the test leads across the source or load under
•
measurement.
The measurement will be shown the LCD Display when the
•
probe are connected.
4.2.3 DC Current measurement
Connect the black test lead to the “COM” socket and red test
•
lead to the “V mA” socket for below 200mA currents. For
measurements between 200mA and 10 A, the red test lead
should be connected to the 10A socket.
Set the FUNCTION/RANGE switch to the desired range in the
•
” function. If the current range is not known beforehand, set
“A
the switch to the highest range and work down as needed.
Connect the test leads in series with the source or load under
•
