Prepare the calibration reference (for example, a reference gas with a known concentration) before starting the adjustment.
When you enter a value into a field, the value is saved automatically when you exit the input field (for example, tap on an area outside of the field).
To make a 1-point adjustment with Indigo wireless configuration interface:
  1. Connect to the wireless configuration interface and open the Calibration menu.
  2. Start the calibration mode with the Start calibration button.
    If you cannot enter configurations after selecting Start calibration, check that the calibration PIN code is in place in the Settings > Probe menu.
  3. If you need to set environmental compensations, enable and set the required compensations on the Configuration tab.
    Note that the environmental compensations you set on the Configuration tab and the compensations you set in the Settings > Probe menu are interconnected: the configuration set in either menu is applied to both.
  4. Remove any possible previous adjustments by restoring the factory adjustment: select Restore factory adjustment for each parameter you are adjusting.
  5. Enter the calibration date and calibration information into the corresponding text fields.
  6. Place the probe in the reference environment (adjustment point 1) and wait until the measurement has stabilized. You can follow the stabilization from the Measurements tab.
  7. Enter the value of the reference (for example, 500 if calibrating with a 500 ppmCO2 reference gas) into the Reference value, point 1 field.
  8. After you enter the reference value, the value of the Measured value, point 1 field updates automatically.
  9. After you have entered the reference point, select Store adjustment to save the adjustment.
  10. Close the calibration mode with the Stop calibration button.
  11. To check that the adjustment was carried out correctly, review the information in the Adjustment data fields at the bottom of the view.
