Hydrazine analyzer

5 Calibration

This section describes how to calibrate the analyzer once it is
operational. Calibration involves measuring the wet-section's
sensitivity to a solution containing a known hydrazine
concentration. Calibrations are initiated via the Cal prompt
displayed on Operator pages, or via the Calibration Level and
Advanced Level menus or as a Scheduled calibration.
Note.

Calibration menus can be accessed from the
Advanced level only – refer to Section 4.3.1, page 20,
steps 2 to 4) to access the Calibrate level.

If calibration standard solution values need to be
changed from their default values, the values must be
set from the Advanced / Calibrate / Calibration Setup
menu only.
Caution.

Do not calibrate the analyzer until the wet-section and
transmitter are installed and ready for operation – refer
to Section 4, page 19.

Allow at least 1 hour for the wet-section to stabilize
before running a calibration.
