I. Safety Information
Do not operate the unit if the casing or the test Leads are or look
damaged.
Check the main function dial to ensure it is set at the correct position
before each measurement.
Do not perform resistance and continuity test on a live “powered
“system.
Do not apply voltage between the test terminals and test terminal to
ground that exceed the maximum limit referred to in this manual.
Exercise extreme caution when measuring live systems with voltage
greater than 60V DC or 30V AC.
Keep fingers behind the protection ring when measuring with test
leads.
Replace batteries when the symbol appears to avoid incorrect
data.

Button Instruction:
Zero Button
Press Zero button to enter the Zero mode, “ZERO” Annunciate will
appear and Zero the display. The reading is stored as reference value
for subsequent measurement.
Press the Zero button again, to exit the zero mode.

Max Hold Button
Press “Max” button to enter the Max mode, “Max” Annunciate will
appear and the Max display. Press the Max button again, to exit the
Max mode.
Back Light Function:
Press the “Back Light” button will turn back light on and Press it once
again will turn off.
The meter will turn back light off if there is no push “Back Light”
button for 30 seconds.
Data Hold &50/60HZ
To activate the Data Hold feature, press the “ Hold ” button.
To de-activate the Data Hold feature, press the “ Hold ” button again.
To activate the Data Hold feature, press and hold the “ 50/60HZ ”
button until the symbol displays.
To deactivate the 50/60HZ feature, press and hold the “ 50/60HZ ”
button for 2 seconds. The meter will return to WIDE mode operation.
Note: This meter is built with 50/60HZ function at ACA, ACmA
ranges.
How to use frequency selector button
When high frequencies from such equipment as inverters are
presented in the circuit under test. This instrument measures AC
current of not only 50HZ or 60HZ of fundamental frequency but also
the harmonics
To eliminate the effect of such high frequency noise and measure
only the AC current of 50Hz or 60Hz fundamental frequency, a
“high-cut” filter is built in this instrument.
When the frequency selector button is pressed “50/60HZ” mark is
shown on the display and when the frequency selector button is
pressed again, frequency response is switched to wide band with
“WIDE” mark shown on the display.
Disable Auto power off
Press and hold “ ZERO ” button and then the power on the meter, the
symbol will disappear.

IV. Measuring Instruction:
4.1 ACA、ACmA measurement:
1.Set the range selector switch to the desired position current to
measure should be within the selected measuring rang.
2.Normal measurement (see Fig.1):
Press the jaw trigger to open the transformer jaws and close them
over one conductor only. Measured current value is shown on the
display. Earth leakage current or small current that flows through a
grounded wire can also be measured by this method.
3.Measuring out of balance leakage current (see Fig.2):
Clamp onto all conductors except a grounded wire, measured current
value is shown on the display.
Before this measurement, disconnect any test lead with the meter for
safety.
In some cases where reading is difficult, press the HOLD button and
read the result later.

4.2 ACV measurement:
WARNING!
Maximum Input Voltage is 600V AC/DC. Do not attempt to Take any
voltage measurement that may exceed this maximum to avoid Electrical
shock hazard and/or damage to this instrument.
Switch the function selector to V ~range.
Connect red test lead to “+” terminal and black one to the
“COM“ terminal.
Measure the voltage by touching the test lead tips to the test circuit
where the value of voltage is needed.
Read the result from the LCD panel.
