Continuing with three-
to five-point calibration
Note
Calibration is automatically completed after the last buffer of a buffer
set has been measured. Then the calibration record is displayed.
The calibration line is determined by linear regression.
15 Thoroughly rinse the IDS pH sensor with deionized water.
16 Immerse the IDS pH sensor in the next buffer solution.
17 When measuring without temperature sensor:
Measure the temperature of the buffer manually and enter it
with <
><>.
18 Start the measurement with <MENU/ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parame-
ter flashes.
19 Wait for the measurement with stability control to be completed
or terminate the stability control and take over the calibration
value with <MENU/ENTER>.
The calibration display for the next buffer appears (voltage dis-
play).
20 If necessary, use <M> to finish the calibration.
The calibration record is displayed.
