Continuing with two-
point calibration
9. Immerse the electrode in standard solution 1.
10. When calibrating without temperature sensor:
 Measure the temperature of the standard solution using a thermom-
eter.
 Use <F4> /[
⇅
] to select the setting of the temperature.
 Use <

> <

> to set the temperature.
 Use <F4> /[
⇅
] to select the setting of the concentration.
11. Set the concentration of the standard solution with <

> <

> and
press <ENTER> .
The standard solution is measured.
The measured value is checked for stability (AutoRead).
12. Wait for the end of the AutoRead measurement or accept the calibra-
tion value with
<ENTER> .
The calibration display for the next standard solution appears.
