In guided calibration, the indicator guides you through the calibration process step by step. At the end, you can also adjust the measurement, if needed.

You can choose to perform either 1-point or 2-point calibration, and choose to use the reference gas or instrument of your choice, for example, another probe connected to your indicator.

Before starting the adjustment:

  • Familiarize yourself with information on adjustment points and requirements for your probe.
  • Make sure that the probe's environmental compensation settings (for example, the pressure value given as the current operating pressure) are correct for your present environment.

  • Always restore factory adjustment before entering a new adjustment. This prevents any possible earlier adjustments having an effect on the new adjustment you make.

  1. Connect the probe(s) to the indicator.
  2. Open the indicator main menu by pressing .
  3. Select Devices, then select the probe to be calibrated.
  4. Select Calibrate / Adjust.
  5. Read the notification and select OK to close it.

  7. Select Guided calibration.
  8. In Calibration points, select the number of calibration points: 1 point or 2 points.
  9. In Reference, select the reference instrument.

    Selection Other reference allows you to use any reference environment(s) of your choice (for example, a reference gas).

  10. Select Start calibration.

The indicator guides you through the calibration process from this point onwards. Press to proceed from one view to another.
