Operating a Combustible Gases Detector:

Power On/Off:

  • To power on the GAO Tek combustible gases detector, locate the power button and press it.
  • To power off, press and hold the power button until the device shuts down.

Sensor Warm-Up:

  • Allow the detector to warm up as specified in the user manual before use.

Gas Sampling:

  • Position the detector near the suspected gas source.
  • Use the built-in pump or follow the manual to collect a sample for analysis.

Visual and Audible Alerts:

  • Familiarize yourself with the visual and audible alarms.
  • Take appropriate action when an alarm is triggered.

 

Maintaining a Combustible Gases Detector:

Cleaning:

  • Regularly clean the external surfaces of the detector with a soft, dry cloth.
  • Avoid using abrasive materials or liquids that may damage the device.

Sensor Maintenance:

  • Refer to the user manual for guidelines on sensor maintenance.
  • Follow recommended procedures for cleaning or replacing sensors.

Battery Maintenance:

  • Monitor the battery level regularly.
  • Replace batteries according to the GAO Tek’s recommendations.
  • Calibration Check:
    • Perform regular calibration checks to ensure accurate readings.
    • If deviations are noted, recalibrate the detector immediately.

 

Calibrating a Combustible Gases Detector:

Preparation:

  • Ensure the detector is in a clean air environment.
  • Confirm that the calibration gas is within its expiration date.

Access Calibration Mode:

  • Follow the instructions in the user manual to access the calibration mode.

Calibration Gas Application:

  • Introduce the calibration gas to the detector according to the specified flow rate.

Adjustment:

  • Use the adjustment controls provided to align the detector’s readings with the calibration gas concentration.

Verification:

  • After calibration, expose the detector to another known gas concentration to verify accuracy.

Documentation:

  • Record calibration details, including date, time, and gas concentration.
  • Keep a log of all calibration events for future reference
