Continuing with two-
point calibration
11 Thoroughly rinse the IDS sensor with deionized water.
12 Immerse the IDS pH sensor in buffer solution 2.
13 When measuring without temperature sensor:
Measure the temperature of the buffer manually and enter it
with <
><>.
14 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.
15 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 pH value of the buffer solution is displayed.
16 Set the nominal buffer value for the measured temperature with
<
><>.
17 Accept the calibration value with <MENU/ENTER>.
The calibration display for the next buffer appears (voltage dis-
play).
18 If necessary, finish the calibration procedure as a two-point cal-
ibration with <M>.
The calibration record is displayed.
