9.3 Zero-point calibration (one-point offset calibration)
✱
Make preparations, see chapter 9.2 "General information", page 60.
✱
Start calibration, see chapter 9.2.2 "Ways to start the calibration", page 61.
✱
Select zero point calibration.
✱
Immerse the combination electrode in a test solution with a known redox
potential.
✱
Start the zero point calibration with the key.
Wait until the display value has stabilized; then press to continue.
✱
Set the displayed value to the test solution value with the or keys;
then press to continue.
The zero point determined by the device is displayed.
✱
Use the key to accept the value or
the key to reject it.
Zero point calibration is only available if the unit is configured as "mV"!
