Calibrating the analyzer

Quick calibrations are initiated via the CAL prompt displayed on
Operator pages. Scheduled calibrations and other calibration
routines must run from the Calibrate level menus (accessed only via
the Advanced access level – see Step
Caution.

Do not calibrate the analyzer until the wet-section and
transmitter are installed and ready for operation.

Allow at least 1 hour for sodium / hydrazine sensors to
stabilize before running a calibration.
Calibrating for the first time
Quick calibration routines (low level dissolved oxygen, hydrazine,
sodium) differ only in the calibration type that is performed:

LLDO = air cal.

hydrazine = high cal.

sodium = two-point cal.
