Operation
Turning on / off
Press and hold the power key for
more than 2 seconds
. A beep sounds
and the display lights up.
Press the power button again and the tester will turn off. After 3 minutes of
non-use, the tester automatically powers off to conserve battery life. The
tester is now deactivated and is not operational.
Checking for the presence of AC voltage
Prior to each use, test on known live circuit to verify
tester functionality!
Keep the tester's tip near the AC voltage. When a voltage is detected, a
beep sounds and the tip lights up red.
As the intensity of the voltage signal changes, the bar graph on the screen
becomes higher or lower and the frequency of blinking and beeping
becomes faster or slower with the signal intensity.
The signal intensity is affected by the distance from the voltage. The further
the tester is from the circuit, the weaker the signal becomes.
Dual range
When the tester is turned on, it is in
low-sensitivity mode (48 ~ 1000V). Briefly
press the green button to enter the high
sensitivity mode (12 ~ 1000V). Refer to the
following table for each mode.
