Notes:
1. The minimum width for the CAL input to initiate a calibration cycle. Pulses shorter than this may be ignored
2. The maximum time to perform the tube calibration cycle.
3. The maximum time to detect blood levels rising above the limit or blood levels falling below the limit.

Sensortechnics is asking customers for a sample of their tubing. The sensor will then be
calibrated for exactly this tubing. For proper function the sensor should only be used
with the tubing which was sent to Sensortechnics!
Custom specific modifications are widely available. Please contact your nearest
Sensortechnics sales office for further information.
