Calibration And Adjustment Of The Internal Pressure Sensor - Sartorius Sartocheck 4 plus Operating Instructions Manual

7.19.3.1 Calibration and
Adjustment of the Internal
Pressure Sensor

Fig. 7-85 | Ambient pressure reference
Fig. 7-86 | Calibration
Connect the Sartocheck 4 plus Bag tester to a supply with sufficient current and
compressed 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 the following pressure range calibration:
– Bag tester only: 0 – 0.6 bar
– Filter tester: 0 – 6 bar or 0 – 8 bar
Reference sensor
F5: Type of sensor (not selectable for the Bag tester)
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 (only valid for the Filter tester),
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 4 plus Bag tester now runs up to the first pressure level. After pressure
stabilization, you are prompted to enter the pressure applied to the reference sensor
into the field "reference pressure". Afterwards, the next pressure level is run auto-
matically, and stabilized. You are again prompted to enter the reference pressure
value. Continue to repeat this procedure until the last pressure level has been pro-
cessed. Then, calculation of the data is performed and, depending on the procedure
selected (calibration or adjustment) the results table is displayed.
The figure 7-82 shows the pressure steps for the Sartocheck
®
4 plus Filter tester.
