4. Analyze the sample again, ensuring that the sample has no
bubbles before introducing it into the sample port. Checking for
bubbles is especially important for samples introduced from
capillary tubes.
If you are analyzing a capillary sample, ensure that you
introduce the fire-polished (smooth) end of the capillary tube
into the sample port.
5. When introducing the sample, introduce the sample device into
the sample port as shown on the screen.
Cal Overdue Calibration was delayed beyond the maximum calibration
interval. The system must perform a calibration before you can
analyze samples.
Cal Not Done The system was unable to perform a calibration until after the
next scheduled calibration. This can occur if the system is left idle
in a state where it cannot perform calibrations. The system
cannot perform calibrations when the wash/waste cartridge is
expired, during diagnostic tests, and during the procedure for
removing obstructions.
When this condition occurs, the Wait screen appears while the
system performs an extended calibration.
Cal Pending Appears 2 minutes before the time of the next scheduled
calibration. The time remaining until the calibration begins
appears with the message.
COox Chamber
Temp Error The system detects that the temperature of the CO-ox sample
chamber is outside the acceptable measurement range. This
message can occur when a new measurement cartridge is
warming up, when the system is warming up after being shut
down, and when the door remains open for too long.
NOTE:
The system can measure samples and report results for
parameters that are still available.
1. Wait until the system removes the message from the Status
screen before analyzing samples.
2. If the message appears again, record the message and call for
technical assistance.
