1. SAFETY 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 ngers behind the 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 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 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 � 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.
