Continuing with two-

point calibration

9 Wait for the measurement with stability control to end.

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.

Enter a value and, if necessary, an exponent with <0...9>.

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.

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.
