Replace Glucose Sensor
The Synchron
®
AccuSense glucose oxygen sensor requires no assembly. Each sensor
has a gasket positioned over the membrane tip. The sensor is discarded after six
months usage on an instrument, at which time a new sensor is installed.
On DxC 800 Systems, the BUNm/UREAm module has an extra glucose sensor
connector located next to the BUNm/UREAm electrode connector. This extra glucose
connector can be used to pre-condition a new glucose sensor prior to installation.
For DxC 600 Systems, follow Steps 1–5 in the table below. Then proceed to Draining
the Reaction Cup for Sensor Maintenance or Replacement.
Preparation Prior to Replacement (DxC 800 Systems)
On DxC 800 Systems, plugging the glucose sensor into the empty connector port,
(labeled GLU on the BUNm/UREAm module) 24 hours before glucose sensor
installation will minimize sensor drift.
Perform the following steps 24 hours prior to replacing the AccuSense glucose sensor.
16 Following calcium electrode tip replacement and calibration:
• Program and run at least 20 replicates of serum samples for CALC.
• Recalibrate calcium.

NOTICE
A new glucose sensor may drift over the first 24 to 48 hours. Always verify
control recoveries after calibration. More Frequent calibration may be required
during the first 24-48 hours following installation.
Step Action
1
CAUTION
Do not touch membrane tip.
Remove the AccuSense glucose oxygen sensor (P/N 467432) from
package.
2 Remove the protective cap from the electrode connector.
3 Check the sensor for the presence of the gasket on the membrane tip. If the
gasket is missing, replace it at this time.
4 Visually inspect the sensor for leakage or puncture of membrane.
