10.3 Inputs for calibration
A keypad that enables you to input the real value you wish to use
for calibration.
In the special case of pH calibration with (a) buffer solution(s), the
value of the buffer solution must be entered. The same applies to
ORP.
This part is also used for the pH temperature compensation value,
if necessary, in the special case of the pH value.
The keypad is used in the same way as a normal numeric keypad.
If an incorrect value is entered or the value is outside the scale, the
value entered appears red and the “Save” button is disabled.
10.4 Validation messages on calibration status
Confirmation message:
n Before deletion, a confirmation message is displayed before
carrying out the process.
Valid calibration messages:
n Calibration has been successfully completed.
n Calibration has been successfully carried out.
Message of incorrect calibration:
n Incorrect offset value. (Offset overflow for sensor permitted)
n Incorrect slope value. (Permitted slope for the sensor has been
exceeded)
n Two points too close. (2 points for pH calibration are not far
enough apart)
10.5 Offset calibration
1. Wait until the sensor has stabilised.
2. Enter the calibration value.
3. Press
‘SAVE’
.
10.6 Slope calibration
1. Wait until the sensor has stabilised.
2. Enter the calibration value.
3. Press
‘SAVE’
.
10.7 Deleting calibration
A confirmation prompt is displayed. There is no analysis of the
measured value; deletion can also be performed if the sensor is
unstable or missing.
Press
‘Delete’
