Calibrations
during 24 hours
after restart The 24-hour calibration period is only necessary after the replacement of
electrodes and/or electrode membranes.
The calibration intervals for the first 24 hours after restart are as follows:
Time after restart Calibration intervals
First 4 hours 1-point calibration Every 30 minutes
2-point calibration Every hour
Remaining 20 hours 1-point calibration Every hour
2-point calibration Every 4 hours
NOTICE: If the restart is caused by c Glu/ c Lac electrode/membrane maintenance
1-point calibrations will be performed every 30 minutes for the first 4 hours and
every hour for the following 20 hours. 2-point calibrations will follow the normal
schedule.
NOTICE: If the calibration schedule is set up to perform calibrations at intervals
less frequent than those programmed for the 24-hour calibration period, the
calibration schedule is overridden.
