Warning ! Dangerous Voltage (Risk of

electric shock).

Caution ! Refer to the user’s manual before

using this meter.

Double! Insulation (Protection Class II).

Alternating Current (AC)

Direct Current (DC)

Either DC or AC

Ground (maximum permitted voltage

between terminal and ground).

The symbol indicating separate collection for

electrical and electronic equipment.

The user Shall be made aware that, if the

instrument is used in a manner not specified

by the manufacturer, the protection provided

by the instrument may be impaired.

The finger or any part of your body shall

not be beyond the barrier of the test probe

when measuring.

Individual protective equipment must be

used if HAZARDOUS LIVE parts in the

installation where measurement is to be

carried out could be ACCESSIBLE.

Not to use the CURRENT SENSOR if the

wear indicator in the JAW OPENING is visible.

1. SAFETY INFORMATION SAFETY

SYMBOLS

The following safety information must be

observed to insure maximum personal safety

during the operation of this meter.

1.1 Do not operate the meter if the body of

meter or the test lead look broken.

1.2 Check the main function dial and make

sure it is at the correct position before each

measurement.

1.3 Do not perform resistance, capacitance,

temperature, diode and continuity test on a

live power system.

1.4 Do not apply voltage between the test

terminals and test terminal to ground that

exceed the maximum limit Value in this

manual.

1.5 Exercise extreme caution when measuring

live system with voltage greater than 60V

DC or 30V AC.

1.6 Keep the fingers after the protection ring

when measuring through the clamp.

1.7 Change the battery when the“ ” symbol

appears to avoid incorrect data.

1.8 Use the DMM indoor, altitude up to 2000m

and temperature 5°C to 40°C.

Maximum relative humidity 80% for

temperatures up to 31°C, decreasing

linearly to 50% relative humidity at 40°C.

1.9 In locations subject to radio frequency

interference, the product may malfunction

and it resets automatically when leaving

this environment.

3. OPERATION

3.1 DC and AC Voltage Measurement

1) Connect the black test lead to “COM” socket and

red test lead to the “VÙHz” socket.

2) Set the selector switch to desired “mV ~” or “V~”

position,

3) Press “SELECT” key to choose “DC” or “AC”

measurement

4) Measure the voltage by touch the test lead tips to

the test circuit where the value of voltage is needed.

5) Read the result from the LCD panel.

3.2 DC Current Measurement

1) Set the selector switch to desired “400A~” or

“3000A~”position .

2) Press “SELECT” key to choose “DC”

measurement.

3) Zero the reading by pressing “RELr” key for a

reading of zero on the display.

4) Disconnect the test leads from the meter.

5) Clamp the Jaws around the one conductor to be

measured. Center the conductor within the Jaw

using the Centering Marks as guides.

6) Read the result from the LCD panel. The arrow in

the Jaw indicates the direction of positive current

flow (positive to negative )
