5. Setup

5.1 Battery Installation

  1. Locate the battery compartment on the back of the device.
  2. Open the compartment cover.
  3. Insert the two AAA batteries, ensuring correct polarity (+/-).
  4. Close the battery compartment cover securely.

5.2 Initial Warm-up

After powering on, the device requires approximately 15 seconds for the sensor to warm up and stabilize. During this period, the display will show a countdown or a 'Please Wait...' message. This warm-up ensures accurate readings and sensor stability. Do not use the device for detection until the warm-up sequence is complete.

6. Operating Instructions

6.1 Power On/Off

  • To Power On: Press and hold the power button (usually the main button on the front) for a few seconds until the display illuminates and the warm-up sequence begins.
  • To Power Off: Press and hold the power button again for a few seconds. The device will power off automatically after 5 minutes of inactivity.

6.2 Selecting Sensitivity Modes

The AGT-1385 offers two sensitivity modes:

  • Low Sensitivity (Lo): Default setting, suitable for general detection. Alarm threshold typically around 2000 PPM.
  • High Sensitivity (Hi): For detecting smaller leaks or pinpointing sources. Alarm threshold typically around 500 PPM.

To Switch Modes: Briefly press the power button (a short press) while the device is on and ready. The display will indicate the current sensitivity mode (Lo or Hi).

6.3 Gas Detection Process

  1. Ensure the device has completed its warm-up sequence.
  2. Select the desired sensitivity mode (High for precise location, Low for general area scanning).
  3. Carefully extend and bend the flexible gooseneck probe to reach the area suspected of a gas leak.
  4. Slowly move the sensor tip of the probe around the suspected leak source (e.g., gas pipes, appliance connections, valves).
  5. Observe the color display for real-time PPM readings. The color of the values will change (e.g., to red) and an audible alarm will sound, with increasing frequency, as gas concentration rises.
  6. Pinpoint the leak by moving the probe to where the PPM reading is highest and the alarm is most frequent.

7. Maintenance

7.1 Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or internal components. Ensure the sensor tip is kept clean and free from obstructions.

7.2 Battery Replacement

When the low battery indicator appears on the display, replace both AAA batteries with new ones to ensure optimal performance and accurate readings. Refer to section 5.1 for battery installation instructions.

7.3 Storage

Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.

8. Troubleshooting

Problem Possible Cause Solution
Device does not power on. Dead or incorrectly installed batteries. Replace batteries with new AAA batteries, ensuring correct polarity.
Inaccurate or inconsistent readings. Insufficient warm-up time; sensor obstruction; low battery. Allow 15 seconds for warm-up. Clean sensor tip. Replace batteries.
Alarm sounds without apparent gas leak. Presence of other volatile organic compounds (VOCs) or strong odors; sensor contamination. Ensure the area is clear of other fumes. Clean the sensor tip. If issue persists, contact support.
Device powers off unexpectedly. Automatic power-off activated; low battery. This is normal after 5 minutes of inactivity. Replace batteries if low battery indicator was present.
