Four-Month Maintenance
Cleaning MC Reagent Lines
Step
10
When priming is complete, insert each reagent straw back into the
appropriate reagent bottle. Verify that the reagent straws are seated
properly and reach down into the reagent. Make sure all reagent bottle caps
are securely tightened and no reagent lines are crimped or pinched.
Select <Close> to exit the pop-up confirmation window.

Replace the glucose sensor and clean the cup and stir bar at this time if the
six-month expiration date has occurred. Refer to Six-Month Maintenance,
"Replace Glucose
proceed to Step 13.
Note: Following maintenance, allow 15–20 minutes for the glucose sensor
to equilibrate prior to sensor calibration.
13
Perform the BUNm/UREAm electrode maintenance if maintenance is due
at this time. Refer to
this chapter. While the BUNm/UREAm electrode is removed, clean the
cup and stir bar as instructed in Steps 15 and 16. If BUNm/UREAm
electrode maintenance is not necessary, proceed to Step 14.
Note: Following maintenance, allow 15–20 minutes for the BUNm/
UREAm electrode to equilibrate prior to chemistry calibration.
Immediately prior to calibration, to ensure there are no bubbles in the
BUNm/UREAm cup only, the electrode surface should be swabbed with
the tip of an applicator that is wrapped in lintless tissue.

Select the desired chemistries. Then select <Drain>.
Note: It is not necessary to select Glucose if the stir bar was cleaned during
the glucose sensor replacement.
