2Ć55 Operating the System
Performing Calibrations from the Analyze Mode
You can perform calibrations from either the Analyze mode or the Menu mode. All
calibrations available on the 840, 850, and 860 are also available on systems with
the CO-ox module—the 844, 845, 854, 855, 864, and 865.
1. Press Calibrate .
The Calibration Type menu appears, as shown in Figure 2-31.

Press Start Calibrating to
begin the calibration.
The cursor appears at the
TwoĆpoint option.
2. Select a calibration type and press Enter .
NOTE:ĄĂ The tHb Slope Calibration requires you to enter a value and to
introduce the slope reagent. Refer to Performing tHb Slope Calibrations, page
2-57, for instructions.
3. Press Start Calibrating .
4. Press Home to return to the Ready screen.
If the Auto Repeat function is on or Flexible Time calibration intervals are selected
and a parameter shows excessive drift, the system prints a report and repeats the
appropriate calibration for the parameter. Refer to Selecting Calibration Frequency
and Automatic Repeat in Section 5 for more information about these functions.
If a sensor does not reach endpoint within 90 seconds, the parameter value appears
on the screen with an asterisk and the message D5 No Endpoint also appears. The
sensor is considered not in calibration until the system completes a successful
calibration.
The metabolite one-point calibration is available only from the Analyze mode.
