Calibrating Water Pressure
Water pressure is already calibrated before shipment, so additional calibration is unnecessary.
The calibration procedure is given as a reference. Only when an abnormality occurs, check
that the calibration coefficient is not far from the manually-analyzed value.
4.9.1
Adjustment calibration using sample water <water pressure>
Preparation
Water pressure meter...1
Calibration procedure
1.
Measure water pressure of the sample water using a water pressure meter other
than this device's and calculate the value.
2.
Press the SAMPLE VALUE button ([x.xxx]) on the PRES. CAL. screen.
The sample water calibration value input screen is displayed.
3.
Enter the manually-analyzed value of the sample water using the numerical key pad
and press [SET].
Input range: 0.000 MPa to 1.000 MPa
Tip
[CLEAR]: Clears the whole value.
[BACK]: Deletes the rightmost number of the value.
The screen returns to the PRES. CAL. screen.
4.
Press [SAMPLE].
A confirmation screen is displayed asking whether to start calibration.
