1. SAFE TY RULES
•
This meter is designed for indoor use at temperatures between 0°C to 40°C and
altitudes up to 2,000m.
•
To 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 600Vrms,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 en-
sure that the circuit is not “live” before opening it in
order to connect the test leads.
4.2.1 DC Voltage measurement
•
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.
