3 When measuring without temperature sensor:
 Measure the temperature of the standard solution using a
thermometer.
 Open the setting window for the temperature value with
[Man. temp.].
 Enter the temperature and confirm with [OK].
4 Thoroughly rinse the electrode with distilled water.
5 Immerse the electrode in standard solution 1.
6 Open the ISE standard input window with [Continue].
7 Select a value from the Concentration list.
or
Enter a value with <0...9>.
or
Cancel the calibration with [Cancel].
Note
To enter a concentration in exponential representation such as
1.00 E2 mg/l:
Enter the mantissa with <0...9> (here: 1.00).
Enter the exponential sign (E) with <- .><- .>.
Enter the exponent with <0...9> (here: 2).
8 Start the measurement with [OK].
The measured value is checked for stability (Stability control).
