Notes:

no contact with the white part of front end of detector body for your finger!

II. Working voltage and working condition

Working voltage: 90V-1000V AC

Working condition:

1) Working Temperature: 0°C\~40°C Storage Temperature: -10°C\~50°C Humidity: ≤95%

2) Altitude: ≤2000m

III. Operation instructions

Activate probe	Press once gently the button labeled with power symbol, buzzer, LED and motor will work concurrently for 0.5 second, indicating detector is activated successfully. While entering the test standby status, LED will flicker two times continuously with the interval of 1.5 seconds.
AC voltage test	1) Under non-vibration mode, put tip of detector close to the object being tested with AC voltage, LED will flick and buzz.2) Under vibration mode, put tip of detector close to the object being tested with AC voltage, LED will flick and buzz and motor vibrate.
Power off automatically	Battery will power off automatically for energy saving if do not use detector about 3 minutes. Buzzer and LED will work concurrently 1 second, indicating power off successfully.
Stop using motor	Press button gently after power on, LED flicker buzzer works, but motor fails to vibrate, a mode called non-vibration (shifting between vibration) and non-vibration mode with button after power on).
Stop using probe	Press button about 2 second to power off the detector with 1 second of buzzer and LED alight 1 second.

IV. Indication for low electricity of battery

Indication for low electricity of battery When battery voltage is lower than 1.75V, LED will flicker 5 times slowly after power on, and buzzer, if any signal, may sound faintly, and motor vibrates weakly. Please replace battery immediately for the test accuracy.

V. Battery replacement

Battery: 2×1.5V AAA

(1). with one hand holding detector body, and thumb of other hand pressing the control position of detector head and extending it backward.

(2). Please take out the upper cover of detector according to the direction as shown in the picture, replace the battery. (See the following picture)

Cleaning
