5.5 Calibration Procedures

MAIN
The CLM III is calibrated by the manufacturer and should require no further
calibration. However, the instrument is equipped with a verification filter to access
and insure accuracy. Also a self-calibration routine can be performed if indicated by
the verification routine.
The monitor is required to be verified for accuracy at least once per month. The last
date when the verify accuracy test was performed will appear on every treatment
printout.
The CLM III monitor is designed to detect component and memory failures that
could potentially result in the display of erroneous information. If an error or
component failure is detected, the system will display an error message and stop
recording parameter values (see Section 6-Warning Messages).

Verification Filter

The verification filter is a specially modified blood chamber attached to the side of
the monitor. It is included with each instrument and can be used to verify that the
instrument is operating within normal parameters (see Section 1-The CRIT-LINE III
At A Glance).
For verification, attach the CLM III sensor clip to its verification filter so that it locks
firmly into place.
NOTE: Each verification filter is instrument specific and should not be
used to calibrate any instrument except the one to which it is attached
