5.2.4 Carrying out manual calibration (ConCal)
Make sure that in the sensor menu, Buffer menu, the ConCal buffer set is
correctly selected (see section 9.1.1 S
ETTINGS FOR PH MEASUREMENTS, page
62).
Use any one to five buffer solutions in ascending or descending order.
20. Wait for the measurement with stability control to be completed or ter-
minate the stability control and take over the calibration value with
<ENTER>.
The calibration display for the next buffer appears (voltage display).
21. If necessary, use <M> to finish the calibration.
The calibration record is displayed.
or
Switch to calibration with the next buffer with <ENTER>.
Calibration is automatically completed after the last buffer of a buf-
fer set has been measured. Then the calibration record is dis-
played.
The calibration line is determined by linear regression.
If single-point calibration was set in the menu, the calibration proce-
dure is automatically finished with the measurement of buffer solu-
tion 1 and the calibration record is displayed.
1. Connect the pH sensor to the meter.
The pH measuring window is displayed.
2. Keep the buffer solutions ready.
3. Start the calibration with <CAL>.
The calibration display for the first buffer appears (voltage display).
