Leakage Current Tester

Leakage Current Tester can detect the precise location of a power leak within a safe distance without direct contact with the power source, and is used to detect electrical leaks caused by fires, earthquakes, or floods.Leakage Current Tester is a new type of intelligent detection instrument that integrates leakage detection, direction indicator lights, and distress alarm functions.The leakage detection function allows for real-time detection of high and low voltage power sources in unknown environments such as urban flooding and earthquake rescue situations, detecting leakage signals and providing firefighters with a safer rescue environment.It also features manual and automatic alarm functions to quickly alert rescuers in case a firefighter is in distress.

3、Leakage Current Tester operating Instructions

1.Powering On and Off: Press and hold the 'Power' button for 3 seconds.After a 'beep' sound, the screen will light up, and the red indicator light will illuminate, indicating the device is powered on.Press and hold the 'Power' button for 2 seconds to turn off the screen and indicator light, thus powering off the device.

2.Screen Sleep Mode: In the power-on state, lightly press the power button once to turn off the screen while the indicator light continues to flash, entering sleep mode.Alternatively, the device will automatically enter sleep mode after 5 minutes of inactivity.Press the 'Power' button again to turn the screen back on.

3.Leakage Detection: In the power-on state, the low-level detection mode (low sensitivity) is enabled by default.Lightly press the 'Function' button (right button) to display a triangle icon on the screen indicating 'High', entering high-level detection mode (high sensitivity).Pressing it again will display 'Off', temporarily disabling the detection function.This cycles through the modes.When approaching wires or other power sources (including situations with electrical leakage in sewage during urban flooding), the device will provide audio and three-color (green, yellow, red) visual alerts.As you get closer to the power source, green indicates a far distance with a continuous single 'beep' sound; green and yellow indicate a closer distance with a continuous double 'beep' sound; and green, yellow, and red indicate a very close distance with a continuous four-beep sound.

4.Manual Alarm: In the power-on state, lightly press the 'SOS' button to enter the strong alarm state.The screen will display 'Strong Alarm'.Press the 'SOS' button again to deactivate the alarm; the screen will display 'No Alarm'.

5.Automatic Alarm: After the detector is powered on, it enters the pre-alarm state after 30 seconds (±2 seconds) of inactivity.During this period (30 seconds ±2 seconds), sufficient movement will cause the device to return to the previous standby mode and cancel the pre-alarm state.If there is no movement during this period (30 seconds ±2 seconds), the pre-alarm will continue for 15 seconds (±2 seconds) before entering the strong alarm state.Sufficient movement during the pre-alarm period (15 seconds ±2 seconds) will also cause the device to return to the previous standby mode and cancel the pre-alarm state.If no movement is detected within (30S±2S) + (15S±2S), the device will enter a high-alert state.Pressing the 'SOS' button will cancel the high-alert state and return to standby mode.

6.High Temperature Alarm: After the detector is powered on, if the ambient temperature continuously exceeds 60℃ for 10 seconds, the detector will emit an alarm sound, indicating that the current ambient temperature is unsuitable for personnel to remain in and that evacuation or special protective measures are required.

7.SCBA Timer: In the power-on state, press and hold the 'SOS' button for 3 seconds.The detector will emit a 'beep beep beep' sound, and the 'Time' display on the screen will change to 'SCBA', entering the SCBA timer mode.Press and hold the 'SOS' button again for 3 seconds, and the 'SCBA' display on the screen will change back to 'Time', disabling the SCBA timer.The reminder method is as follows: a reminder is given at 20 minutes, another at 25 minutes, and at 30 minutes, the device enters a high-alert mode to indicate that the timed period has been reached.

4、Leakage Current Tester operating and Storage Environment

1.Operating temperature: -20℃ to +70℃

2.Relative humidity: (30-93)%

3.Storage temperature: -20℃ to +70℃

4.Atmospheric pressure: (86-106) kPa

5、Leakage Current Tester maintenance and Care

1.During daily use, check the battery level after each use and charge the device promptly if the battery is low to avoid prolonged periods of low battery power.

2.When storing the device for an extended period, maintaining a battery level of 30%-80% is beneficial for battery life.Check the battery level every 2-3 months and recharge if it is too low.

3.If the device is dirty, wipe it with a damp cloth.A neutral detergent can be used if needed.Clean and dry the device before storing it.The use of strong acid or alkaline solutions, gasoline, or other harsh chemicals for cleaning is strictly prohibited.

6、Leakage Current Tester precautions

1.This detector has a sealed, waterproof structure and must be repaired by professional personnel only.

2.The rechargeable battery must not be replaced with any other type of battery.

3.Before using the detector, please check the battery level.If the yellow low-voltage indicator light on the top of the detector casing is not flashing, and the battery level indicator shows 75% or more, the detector can be used normally; if the low-voltage light flashes before use, it must be charged.

4.Before using this product, inspect its appearance. Detectors with damaged or cracked casings must not be used in rescue operations.

5.Before using the detector, you must carefully read the instruction manual and become proficient in its operation and functions.

6.The detector should be stored in a well-ventilated, dry place free from corrosive gases.

7.Do not charge the battery in flammable or explosive environments.Do not disassemble or replace the battery in explosive gas environments.
