Sartorius Sartocheck 4 plus - Calibration and Adjustment of the External Pressure Sensor Input

Operation 65
The calibration of the external pressur sensor input is only valid for the Sartocheck® 4
plus Filter tester and the Filter tester MultiUnit. Connect the Sartocheck
®
4 plus to the
current and compressed air supply. Connect the electrical outlet “Ext. Sensors” to the
external reference current source (4-20 mA). Enter the data on your reference into
the designated list (see Figure 7.34).

With Page Down, start the actual calibration and|or adjustment.
Enter the corresponding target value of the reference current supplied and wait
for approx. 3 s. If there is a difference between the predefined value and the value
read by the reference, then enter the read-in value in the table. If the values match
exactly, go with PAGE DOWN to the next reference point. Continue to repeat this
procedure until the last reference point has been run up and processed. Calculation
of the data is now complete. Depending on the procedure selected (calibration or
adjustment), the results table is displayed.
During calibration, the results are displayed as a deviation of the adjustment curves.
This classified result is output in addition to the table providing the values for
the current supplied. Use “Print” to generate a printout for the calibration just
carried out.
During adjustment, a new adjustment curve is calculated and activated using
the entered values. The data of the adjustment can be printed out on the internal
printer after the adjustment is completed. The new adjustment curve can then
be checked with a calibration.
“Page up” takes you back to the selection screen for test units (MultiUnits) and
sensors. “Page down” is used to immediately start an additional calibration or
adjustment, depending on “F10 perform calibration | adjustment?”.
