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 refer 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.

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, to exit the zero mode.
Data Hold & Peak Hold 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 peak hold
function by press and hold the “ PEAK ” button. When the
symbol display, the user should release the button and
function will stay at the peak hold mode. If the user press
and hold the button for more than 2 seconds, the tester will
be in normal mode again.

4.3 ACV 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 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.
