5.4 Canceling calibration
You can cancel the calibration test in progress or the
entire calibration procedure at any time by pressing
press .
Canceling the test in progress
To cancel the particular test in progress, retract the
sample handler cradle. The system prompts you to retest
with a new sample.
NOTE: You can cancel individual tests as often as
necessary. Cancellation of an individual test does
not count toward the limit of two failures within a
calibration set.
Canceling the entire calibration
If you cancel the entire calibration, the instrument
maintains the last successful calibration.
1. To cancel the entire calibration, press .
A confirmation prompt appears.
2. At the confirmation prompt, press Yes to confirm
cancellation, or No to continue calibration.
If you press Yes to confirm cancellation, the system
discards any data from this calibration and returns
you to the Home screen.
5.5 Calibration errors
The following table lists errors that can occur during
Calibration.
Error Possible cause/Suggested action
Calibration failed Action: Repeat calibration.
Calibration
required
Cause: A significant maintenance event
has occurred (for example, the probe
resistance has been changed).
Action: Recalibrate the instrument.
Calibrator out of
range:
0 mOsm/kg,
50 mOsm/kg,
850 mOsm/kg, or
2000 mOsm/kg
Cause: Too much variation in the
replicates for the calibrator group.
Action:
• Confirm good technique.
• Confirm sample handler is in good
condition.
• Check for particulates in sample.
Out of range: Low
Out of range: High
Cause: The result for the calibrator is
below/above the expected range for
that calibrator group.
Action: Make sure you are using the
correct calibrator.
Sample did not
freeze
See Maintenance and troubleshooting.
Sample pre-freeze See Maintenance and troubleshooting.
Test timeout See Maintenance and troubleshooting.
Two replicate
failures
Cause: Two individual test failures
occurred within the same calibrator
group.
Action: Repeat calibration.
Wrong calibrator:
0 mOsm/kg,
50 mOsm/kg,
850 mOsm/kg, or
2000 mOsm/kg
Cause: The result for the calibrator was
above or below the expected range for
that calibrator group two times.
Action: Make sure you are using the
correct calibrator.
