Any two solutions can be used for AUTO calibration however if solutions other than those listed above
are used for calibration then the calibration values must be entered manually.
STAND is standardization, a single point calibration. Standardizations are typically used to adjust the
process reading to agree with a laboratory determined “grab sample” reading.
MANUAL is a data entry screen. Manual calibration allows the user to enter a concentration with the
corresponding mV value and a slope for an electrode. Laboratory generated calibration data for an
electrode can be input to a remote analyzer where calibration is difficult or impractical.
TEMP allows the displayed temperature to be trimmed to agree with actual
process temperature.
