I. Safety Information

Do not operate the tester if the body of meter or the test

lead look broken.

Check the main function dial and make sure it is at the

correct position before each measurement.

Do not perform resistance and continuity test on a live

power system.

Do not apply voltage between the test terminals and test

terminal to ground that exceed the maximum limit record in

this manual.

Exercise extreme caution when measuring live system with

voltage greater than 60V DC or 30VAC.

Keep the fingers after the protection ring when measuring

through the test lead.

Change the battery when the symbol appears to avoid

incorrect data.

Button Instruction:

Zero Button

Press Zero button to enter the Zero mode, “△” annunciate

turn on and Zero the display and the reading is stored as

reference value for subsequent measurement.

Press it again, the “△” annunciate blinking and memorized

reference value will display.

Press and hold down zero button for 2 second to exit the

zero mode.

When the tester is under zero mode the auto range function

will be disabled.

Data Hold & Manual Range Button

The user may hold the present reading and keep it on the

display by pressing the “Hold ” button.

When the hold data is no longer needed, one may release

the data-hold operation by press “ Hold “ button again.

One may hold present reading by press the hold button

instantaneously. One may also change the measuring scale

range by press and hold the ☉RANGE button. When the

decimal point changes, the user should release the button

and scale range will stay at the setting range. If the user

press and hold the button for more than 2 seconds, the

tester will be in auto range mode again.

Disable Auto power off

Press and hold “ ZERO ” button and then the power on the

meter.

IV. Measuring Instruction:

4.1 AC Current Measurement:

Switch the main function selector to A range.

Open the clamp by pressing the jaw-opening handle and

insert the cable to be measured into the jaw.

Close the clamp and get the reading from the LCD panel.

Note:

Before this measurement, disconnect the test lead with

the meter for safety.

In some occasion that the reading is hard to read, push

the HOLD button and read the result later.

4-2 DC Current Measurement

Switch the main function selector toA rang.

Press ZERO button to enter the zero reading.

Before measuring current larger than 40A, adjust the

scale to 400A range by press the range button then

perform auto zero operation.

Open the clamp by pressing the jaw-opening handle and

insert the cable to be measured into the jaw.

Close the clamp and get the reading from the LCD panel.

Note:

Before this measurement, disconnect the test lead with

the meter for safety.

In some occasion that the reading is hard to read, push

the HOLD button and read the result later.

4.3 AC Voltage Measurement:

WARNING!

Maximum Input Voltage is 600V AC/DC. Do not attempt to

Take any voltage measurement that may exceed to avoid

Electrical shock hazard and/or damage to this instrument.

Switch the main function selector to V range.

Connect red test lead to “+” terminal and black one to the

“COM“ terminal.

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

circuit where the value of voltage is needed.

Read the result from the LCD panel.
