6.3 Pressure Calibration Procedure
To perform the pressure calibration two points have to be defined
allowing the calculation of new OFFSET and GAIN values.
— Press the PROGRAM
key.
— Skip date and the time setting by pressing the PROGRAM key
six times.
— CODE: ∅∅∅ will be displayed.
— Select the Technician Code (011) by the UP/DN keys and press the
PROGRAM
key.
— Select CALIB CODE: 107 to calibrate the system by means of the
UP/DN keys and press the PROGRAM key again until the
system displays: PRES CAL: ∅∅∅
— Press the PROGRAM
key.
The following is displayed:
Point 1 – Upper Row A 100 R 100
Point 2 - Lower Row A 300 R 300
— Open the door, do not alter A 100.
— Press the PROGRAM key, the cursor will move to R
100.
— Press the PARAMETERS key. The system performs reading
pressure and displays it instead of R100. E.g. R97 (i.e. the system
reads out 97kPa, when the door is open).
— Press the PROGRAM
key.
— The cursor moves to the lower row to A300.
If the system reads out 280kPa, do not change A300. Press the
PROGRAM
key to move to R300 and change it to the actual
pressure value 280kPa by means of the keys UP/DN.
— Press the PROGRAM
key again.
The system calculates the new values for offset and gain and stores
these values in the non-volatile memory.
This completes the calibration procedure for the pressure.
