Manually bump testing G7 with multiple gas cylinders

Written by Carmen Bronsch | April 30, 2019

If you do not have one gas cylinder containing the entire gas mix to bump test your G7 device, you will need multiple gas cylinders to complete these tests on the different sensors.

To bump test G7 with multiple gas cylinders:

  1. Determine the gas order you need to bump test your gas sensors in.

    For more information on determining gas sensor bump testing order, refer to our support article on G7 Gas Sensor Bump Testing and Calibration Order.
  2. Open the main menu on your device by pressing OK.
  3. Navigate to Gas options using the up and down arrows and press OK.

  4. Navigate to Bump test using the up and down arrows and press OK.

  5. When prompted, select yes to start the bump test.

    G7 will do a self test of its lights, sounds, vibration, and ambient noise before the Select sensors screen opens.

  6. Referencing your gas order list to ensure that you are bump testing in the correct sequence, select the gas sensor(s) you want to test, clearing any sensors that do not match the gas cylinder mix you are using.

  7. Select Start bump by pressing OK.

  8. Apply the correct gas mix when G7 prompts you on the screen.

    When G7 is finished bump testing your selected sensor(s), any sensors you previously cleared will appear on the screen.
  9. When your G7 prompts you, turn your gas off, press OK, and follow the next screen prompt.
  10. To bump test the next sensor, repeat steps 6 through 9 until all sensors have been bump tested.
