800 Series Operator's Manual5Ć60
Use this procedure to select the frequency at which automatic calibrations occur
and to direct the system to repeat calibrations automatically whenever the drift is
out of limits. There are two calibration frequency options: fixed time and flexible
time. Table 5-24 describes the Calibration Frequency and Auto Repeat options.
Fixed Time Lets you schedule one- and two-point calibrations to occur at regular
intervals. You enter the time intervals in the One-point Interval and
Two-point Interval fields. With Fixed Time, you can also control the
Auto Repeat function.
One-point intervals range from 05 to 60 minutes; default is 30 minutes.
Two-point intervals range from 120 to 240 minutes; default is 120
minutes.
The tHb slope interval ranges from 1 to 30 days; default is 30 days.
Flexible Time The system determines the rate of drift and schedules the time of the
next calibration to avoid excessive drift in subsequent calibrations.
Flexible Time schedules the one-and two-point calibrations and lets
you define a minimum time interval for one-point calibrations.
Auto Repeat is always turned on when you select flexible time.
Auto Repeat This option is available when you select Fixed Time frequency. You
can choose to have the system automatically repeat the calibration or a
portion of a calibration when the drift is out of limits. The default
value is On.
In Flexible Time, all calibrations automatically repeat when the drift is
out of limits.
NOTE: The tHb slope does not automatically repeat when the drift is
out of limits.
Metabolite
Recal
This option allows you to turn off the metabolite recal. Turning off
metabolite recal allows faster throughput of samples. When you turn
off metabolite recal, the system calibrates glucose only at the regularly
scheduled one- and two-point calibrations.
