8. Thoroughly rinse the electrode with distilled water.
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 calibration
value with <ENTER>.
The calibration display for the next standard solution appears.
