1. SAFETY INFORMATION
Do not operate the tester if there is any sign of damage to the tester
or the test leads.
Check the main function dial and make sure it is in the correct
position before each measurement.
Do not perform resistance and continuity tests on a live power
system.
Do not apply voltage between the test terminals and test terminal to
ground that exceed the maximum limits stated in this manual.
Keep your fingers behind the protection ring on the test probes
when using the test leads.
Change the battery when the symbol appears to avoid incorrect
data.

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.
