Position Error
D73 Qualifier Descriptions
D73 indicates a failure of the sample chamber to reach an open or closed
position and occurs during PUI and each zero, full calibration, wash, and
sample analysis.
The current sample is discarded unless detected after the measurement
phase of the operation is completed. Sample measurements are not
allowed until the error is cleared.

Probable Cause and Corrective Action
The system detects that the CO-ox sample chamber is unable
to open or close correctly. Results for the current sample may
be available if error occurred during the wash after the sample
was analyzed.
1. When prompted, shut down the system as described
in Shutting Down the System, page 256, wait 10 seconds,
and then turn the system on.
2. If the message appears again, replace the cartridges. Refer
to Replacing the Measurement and Wash/Waste Cartridges
in Section 3 of the Rapidpoint 400 Series Operator's
Manual.
3. If the message appears again, record the message and call
for technical assistance.
Service Solutions
