Main calibration
The main calibration of the electrodes must be performed periodically. It also needs
to be performed after certain maintenance actions.
For the indirect method, the sodium (NA-I) and potassium (K-I) tests are calibrated
with a two-point calibration using ISE Solution 1 and 2.
The main calibration is typically performed during the Prepare phase and, if there
follows a second shift, at the end of a shift. It is integrated in the Daily Prepare
Actions maintenance action.
