5. Setup

5.1 Battery Installation

  1. Open the battery compartment cover on the back of the device using the provided screwdriver.
  2. Insert three (3) AAA batteries, ensuring correct polarity (+/-).
  3. Close the battery compartment cover and secure it with the screw.

5.2 Initial Power On and Preheating

  1. Press and hold the Power On/Off button (Power button icon) to turn on the device.
  2. The LCD will display "ZERO WAIT...." and a countdown. Place the device in a clean air environment (free from gas) and wait for approximately 30 seconds for the sensor to preheat and stabilize. This ensures accurate readings.
  3. Once preheating is complete, the device is ready for use.

6. Operating Instructions

6.1 Gas Detection

  1. After preheating, move the flexible gooseneck probe slowly towards the suspected area of a gas leak.
  2. Observe the LCD display and listen for the audible alarm.

6.2 Sensitivity Modes (LOW/HIGH)

The device offers two sensitivity modes:

  • LOW Sensitivity: Use this mode to quickly identify the general area where a gas leak might be present. Press the 'LOW' button to activate.
  • HIGH Sensitivity: Once a general area is identified, switch to 'HIGH' sensitivity by pressing the 'HIGH' button to pinpoint the exact source of the leak.

6.3 Audible and Visual Alarm

As the concentration of combustible gas increases, the device will provide dual alarms:

  • Visual Alarm: The analog bar on the LCD display will change color from blue to yellow, then to red, indicating increasing gas concentration.
  • Audible Alarm: A beeping sound will become faster as the gas concentration rises. The alarm triggers when the concentration reaches 300 PPM.

6.4 Muting the Alarm Sound

Press the Alarm Sound On/Off button (Alarm sound icon) to silence the beeping sound. Note that the device will still beep if the gas concentration exceeds 300 PPM, even if muted.

6.5 Temperature Units Selection

Press the °C/°F button (Temperature unit switch icon) to switch the temperature display between Celsius and Fahrenheit.

6.6 Automatic Shutdown

The device has a 10-minute automatic shutdown feature to conserve battery life. To toggle this feature on or off, briefly press the Power On/Off button (Power button icon) during operation.

7. Maintenance

7.1 Battery Replacement

When the battery indicator shows low power or the device emits a continuous beeping sound, replace the three AAA batteries promptly to ensure optimal performance.
