AC voltage test| 1)Under non-vibration mode, put probe of test pencil close to
the object being tested with AC voltage, LED will flick and buzz
2)Under vibration mode, put probe of test pencil close to the object being
tested with AC voltage, LED will flick and buzz, and motor vibrate.
Power off automatically| The battery will power off automatically for energy
saving if do not use the test pencil for about 3 minutes Buzzer and LED will
work concurrently for 1 second, indicating power off successfully.
Stop using motor| Press the button gently after powering on, LED flickers
buzzer works, but the motor fails to vibrate, a mode called non-vibration
(shifting between vibration and non-vibration mode with button after power
on).
Stop using t est pencil| Press the button for about 2 seconds to power off the
test pencil with 1 second of the buzzer and LED light for 1 second.
Indication for low electricity of the battery
IV. Indication for low electricity of battery When the battery voltage is lower than 1.75V, the LED will flicker 5 times slowly after powering on, and the buzzer, if any signal, may sound faint, and the motor vibrates weakly. Please replace the battery immediately for test accuracy.
Battery replacement
