5. BUTTON INSTRUCTION
5-1 HOLD & LPF Function
It is possible to freeze the value displayed by pressing on the
"HOLD" button. Press the "HOLD" button again to exit the Hold
mode.
To activate the Low Pass Filter (LPF) feature, press and hold the
“LPF” button until the symbol displays. To deactivate the LPF
feature, press and hold the “LPF” button for 2 seconds. The meter
will return to normal mode of operation.
The Cut-Off frequency of the low pass filter is about 160Hz
with attenuation characteristic of approx. -24dB/octave.
Note: The LPF function operates on the AC A and AC mA ranges.
5-2 PEAK Hold & / Function Selection
Press "PEAK" button to enter the PEAK mode, the meter records
the peak maximum value. Press the "PEAK" button again, to exit the
peak mode.
When you turn the rotary switch to the Ohms/Continuity Test
position, press the "PEAK" button to select Resistance
measurement, press the "PEAK" button again to select continuity
test with buzzer.
5-3 ZERO Function
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.
5-4 BACKLIGHT Function
When the " " button is pressed, the backlight will be turned on.
Press the button again to turn the backlight off. If the button is not
pressed again then the backlight will be automatically turned off in
about 30 seconds after it is turned on.

6. MEASURING INSTRUCTION
6-1 ACA、ACmA Measurement:
(1) Set the range selector switch to the desired position. The current
to be measured should be within the selected measuring range.
(2) Normal measurement (see Fig.1):
Press the jaw trigger to open the clampmeter jaws and close them
over one conductor only. The measured current value is shown on
the display. Earth leakage current or any small AC current that flows
through a ground wire can also be measured by this method.
(3) Measuring out of balance leakage current (see Fig.2):
Clamp onto all conductors except the ground wire. The measured
imbalance current value is shown on the display.
Before this measurement, disconnect any test leads from the meter
for safety.
In some cases wherein reading the display is difficult, press the
HOLD button and read the result after the clamp is removed from the
conductors.

6-2 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 main function selector
to range.
Connect the red test lead to the
"+” terminal and the black lead to
the “COM” terminal.
Measure the voltage by touching
the test lead tips to the test circuit
where the voltage measurement
is required.
Read the result from the LCD
display.

6-3 DCV Measurement：
Switch the main function
selector to range.
Connect the red test lead to
the “+” terminal and black
lead 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.
6-4 Continuity Test With Buzzer：
Switch the main function to range.
Connect the red test lead to the “+” terminal and the black lead to
the “COM” terminal.
Connect tip of the test leads to the points between which continuity
is to be measured.
If the resistance is under 45Ω, the beeper will sound continuously.
Short circuit Open circuit

6-5 Resistance Measurement
Switch the main function to
range.
Connect the red test lead to the
“+” terminal and the black lead to
the "COM" terminal.
Connect tip of the test leads to
the points where the value of the
resistance is to be measured.
Read the result from the LCD.
Note :
When measuring resistance in a
circuit, make sure any power on
the circuit is turned off and any
capacitors are discharged.
7. CHANGING THE BATTERY
When the battery voltage drops below that required for proper
operation of the instrument, the battery symbol will appear on the
LCD display and the battery should be changed.
Before changing the battery, switch the main dial to “OFF ”and
disconnect test leads.
Open the back cover using a screwdriver.
Replace the old batteries with two new 1.5V (AAA Size) batteries.
Close the back cover and tighten the screw before using the meter.

8. MAINTENANCE
WARNING!
Before opening the meter, disconnect both test leads. Never use the
meter unless the battery cover is in place and the screw is tightened.
CAUTION!
To avoid contamination or static damage, do not touch the circuit
board without proper static protection.
8-1 REMARK:
If the meter is not going to be used for a long time then please remove
the battery and do not store the meter in a high temperature or high
humidity environment.
Keep the cable in the center of the clamp will return a more accurate
test result when making current measurements.
Repairs or servicing not covered in this manual should only be
performed by qualified personnel.
8-2 CLEANING:
Periodically wipe the case with a dry cloth. Do not use abrasives or
solvents on these instruments.
