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 Sensor , in this
chapter. If replacement is not necessary, 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
Monthly Maintenance,
Clean All Cup Modules , in 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. To ensure there are no bubbles in the BUNm/UREAm cup, immediately prior
to calibration, wrap the tip of an applicator stick with lintless tissue and swab the electrode surface.

.
NOTE
It is not necessary to select Glucose if the stir bar was cleaned during the glucose sensor
replacement.
CAUTION
Remove the Glucose sensor before removing the stir bar. To prevent damage to
the glucose sensor membrane tip, do not insert the stir bar removal tool,
applicator stick, or any other object into the glucose reaction cup unless the
sensor has been removed.
CAUTION
Loosen the BUNm/UREAm electrode retainer nut, approximately one-half turn,
and withdraw electrode slightly before removing the stir bar. This prevents
possible damage to the delicate electrode tip.
15
Using the stir bar removal tool (1) Figure 9.32 , remove the stir bars from all cups (not necessary
for Glucose if the stir bar was previously cleaned during maintenance). Clean the cups with
cotton swabs moistened with deionized water. Be sure to moisten the swabs before inserting
them into the cups.
