7.16.3.1 Calibration and Alignment of the Internal Pressure Sensor

Connect the Sartocheck
air (max. 7-10 bar). Connect, the outlet "OUT" to your reference sensor. Enter the
data of your reference in the designated list. In the event that you have a relative
pressure sensor as reference, enter the data in the list on the next page.
Service Menu Calibration|Adjustment
TU1: Internal pressure sensor
F1: Select operational step adjustment
F2: Enter pressure range calibration in bar: 0–6 bar|0-8 bar
Reference sensor
F5: Type of sensor; absolute pressure sensor or relative pressure sensor
F6: Identification (e.g. manufacturer)
F7: Serial number
F8: Certificate number
F9: Internal number
F10: Remarks
The information for describing the reference sensor has no effect on the actual
calibration|adjustment, but is entered for documentation purposes and is printed
out on the records accordingly.
If a relative pressure sensor is used as reference , enter the additional specifications
for the ambient pressure reference into the corresponding list.
Service Menu calibration
TU1: Internal pressure sensor
F1: Unit of measure
Ambient pressure in mbar (abs); only shown if the relative pressure sensor has been
selected
F4: Identification of reference current source (e.g. manufacturer)
F5: Serial number of reference
F6: Calibration certificate number
F7: Internal number
F8: Remarks
With Page Down, start the actual calibration and|or adjustment.
Sartocheck ® 3 plus now runs up to the first pressure level. After pressure stabiliza-
tion, you are prompted to enter the pressure applied to the reference sensor into the
field "reference pressure". Afterwards, the next pressure level is run automatically,
and stabilized. You are again prompted to enter the reference pressure value.
Continue to repeat this procedure until the last pressure level has been processed.
Then, calculation of the data is performed and, depending on the procedure
selected (calibration or adjustment) the results table is displayed
® 3 plus to a supply with sufficient current and compressed
