• Verify that the pump is operating by resetting the mode and listening for audible pump
operation noise.
• Refer to Section 5, Pneumatic Operation, for additional information.
Calibration Advisories
Calibration advisories interrupt the calibration operation until the condition is cleared. The
calibration sequence continues after the condition is addressed by the host/user. Calibration
advisory messages include 21 through 26.
Calibration advisories are listed in the following table.
21, Calibration Already in Progress
The Module has received a command to initiate a new calibration sequence while the Module is
already running calibration.
22, Calibration Not in Progress
The Module is receiving calibration data commands from the host before the calibration
sequence is properly initiated.
23, Low Run Time
The Module has not been running in measurement mode or autorun mode for 5 minutes prior to
receiving the calibration command from the host.
NOTE Removing the watertrap during a calibration sequence causes the calibration procedure
to abort and resets the 5-minute run time clock. Module operation during calibration
differs from normal autorun or measurement mode operation.
Status
Message Code
(hex) Definition Possible Causes
21 calibration already in
progress • calibration command received from host while
Module calibration sequence already in progress
22 calibration not in progress • Module receiving calibration commands before
calibration sequence properly initiated by host
23 low run time • Module has not met run time requirement of 5
minutes
24 calibration ready for next
step • Module ready to accept host data to proceed with
calibration
25 calibration in progress • valid Module calibration procedure initiated by
host; Module presently sampling.
26 calibration ok • Module calibration successfully completed and
new constants stored in EEPROM
