[2.20.04] Calibrate pressure sensor ULTRAMAT 7
Procedure
1. Main menu > "2. Settings" > "20. Service > "04. Calibrate pressure sensor".
This function calibrates the pressure sensor. A linear correction coefficient is used for this
purpose. The device is then capable of correcting fluctuations of the sample gas
pressure.
The actual value and the currently calibrated offset of the pressure sensor for the sample
gas are displayed. In addition, the linear factor specifically for the measured gas is
displayed.
The display and procedure also apply to the CALOMAT 7 analyzer module: → [2.20.04]

2. Start calibration wizard:
– Authorize access with Expert PIN, if necessary.
– Select the calibration variant:
Calibration vari-
ant
Short description
1-point calibra-
tion
If you select this calibration, the offset of the pressure characteristic curve
is decided. The slope (linearization factor) remains unchanged.
2-point calibra-
tion
With this calibration, offset and slope (linearization factor) are determined.
In addition to this, to noticeably different pressure values are required.
– Follow the instructions of the wizard.
– The actual pressure values as well as the sample gas offset are displayed after
successful calibration. In addition, the current linear factor is displayed.
