Continuing with two-
point calibration
9 Wait for the measurement with stability control to end.
or
Take over the calibration value with
[OK] .
The ISE standard input window for the entry of the concentra-
tion of the second standard solution pops up.
10 Select a value from the ISE-Std list.
or
Enter a value and, if necessary, an exponent 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).
11 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] .
12 Thoroughly rinse the electrode with distilled water.
13 Immerse the electrode in standard solution 2.
14 Start the measurement with [OK] .
The measured value is checked for stability ( Stability control ).
15 Wait for the measurement with stability control to end.
or
Take over the calibration value with
[OK] .
The ISEX calibration window for the nex standard solution
pops up and the Finish with 2-point calibration infotext is dis-
played.
