A: To replace the batteries, open the battery cover (1) and insert two AAA batteries following the correct polarity.

AC Voltage Detector User Manual

Introduction

This product is powered by two AAA batteries, it’s an AC voltage detector with dual sensitivity switching, it has an acousto-optic alarm, flashlight and other functions.

Warning
To avoid electrical shock or personal injury:

1. Please use this detector strictly according to this manual, otherwise, the protection function provided by the detector may be affected.
2. If the power indicator in not on, please do not use.
3. Before use, test on the electrified power supply, to guarantee the product is under sound working conditions.
4. Before using this detector, even if there’s no sound or light alarm, voltage may still exist. The detector only indicates the valid voltage when there’s AC voltage generating an electrostatic field with sufficient intensity.
5. If the electric field intensity is very low, the detector may not detect it. The detector may be affected by the following factors, and these factory include but not limited to: Shielded wires/cables, insulation layer thickness and type, distance from voltage source, complete insulation layer, socket design difference etc.
6. If the detector is damaged, or the detector cannot work normally, please do not use it.
7. Please do not apply voltage exceeding the rated voltage indicated on the detector.
8. When testing voltage above AC 30V, be very careful, to avoid electric shock.
9. Please comply with local and national safety codes. Use proper protective equipment according to f to the regulations of local or national authorities.

Operation Instructions

1. Turn on/off
   Press the power on/off button for two seconds, the buzzer makes alarming sounds ， The flashlight, signal intensity indicator, signal strength indicator band, power/low battery indicator, and sensitivity switching button indicator flash once at the same time. When no AC signal is detected, the power indicator will change to the breathing indicator state with the current standby. When the detector is on, press the power on/off button, to turn off the detector.

2. Low/high sensitivity switch
   At first, it’s low sensitivity, the ac voltage range is about 48-1000V, when press the “S” button, the button indicator is light to indicate the current state of high sensitivity, the ac voltage range is about 12-1000V. Press the button to switch the low/high sensitivity.

3. Turn on/off the flashlight
   When the detector is on, press the flashlight on/off button to turn/off the flashlight.

4. Automatic power-off function
   When there’s no operation of the detector or there’s no signal detected range by the detector, the detector will power off automatically.

5. AC voltage detection
   Insert the probe of the tester into the power socket or get close to the live wire, when the tester defects AC voltage signal, The LCD screen displays the signal strength in a single bar. The LCD bar status, signal indicator, and buzzer also change with the signal strength. When a strong signal is detected, the single cell is full, and the LCD green screen turns to red. At the same time, the signal indicator light and the buzzer are synchronized to the highest operating frequency.

6.  Neutral line/live wire judgment
   Separate two wires to be tested as far as possible, and then use the probe of the detector to get close to the wires, for the socket, insert the probe into the socket, and the one with a strong induced signal detected by the detector is a live wire, while the one with weak induced signal or without induced signal is a neutral line.

7. Battery undervoltage indication
   When the battery voltage is low, the power/low battery indicator is steady red. Please replace the battery timely.

8. Temperature display
   When no voltage signal is detected after the power supply is turned on, the LCD screen displays the reading value of the current ambient temperature degree Celsius. Long press (Figure 2) to switch the reading value of Fahrenheit.
