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.

9
4.3 DCV measurement:
Switch the function selector to Vrange.
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.

10
4.4 Resistance measurement:
Switch the function selector to range.
Connect red test lead to “+” terminal and black one to the “ COM ”
terminal.
Connect tip of the test leads to the points where the value of the
resistance is needed.
Read the Ohm value from the LCD panel.
Note:
When measuring resistance value from a circuit, make sure the
power is cut off and all capacitors are discharged.

11
4.5 Continuity Test:
Switch the function selector to range.
Connect red test lead to “+” terminal and black one to the “ COM ”
terminal.
Connect tip of the test leads to the points where continuity is to be
tested.
If the resistance is under 35Ω, the beeper will sound continuously.
Beeper

12
4.6 Frequency measurement from the terminals:
Switch the main function to “Hz ”range.
Connect red test lead to “+” terminal and black one to the “ COM ”
terminal.
Connect tip of the test leads to the points where the frequency of the
voltage signal is needed.
Read the Result from the LCD panel.

13
4.7 Frequency measurement with the clamp:
Switch the main function selector to“Hz ”range.
Open the clamp by pressing the clamp-opening handle and insert the
cable to be measured into the clamp.
Close the clamp and get the reading form the LCD panel.
Note:
When doing frequency measurement, user should either use the
terminal signal or clamp signal but not both. If both sources are
applied an error reading will occur.

14
V. Battery Changing:
1.When the battery voltage drops below proper operation range the
symbol will appear on the LCD display and the battery will need
to be changed.
2.Before changing the battery, switch the function selector to “OFF ”
and disconnect test leads.
Open the back cover using a screw driver. Replace the old batteries
with two UM-4 or AAA size batteries.
3.Close the back cover and fasten the screw.

15
VI. Maintenance:
CAUTION
To avoid contamination or static damage, do not touch the
circuit board without proper static protection.
REMARK
* Remove the batteries, if the meter is not used for extended
periods of time. Do not store the meter in a high
temperature/humidity environment.
* When measuring current, keep the cable at the center of the
clamp to get more accurate readings.
CLEANING
Periodically wipe the case with a dry cloth and without
detergent. Do not use abrasives or solvents on this instrument.
