Sensor start

Paradigm 522 and 722 pumps offer 3 possibilities to activate the sensor under the menu option Sensor / Start. These are:

The function is named Sensor Start which is bit misleading. Starting the sensor technically means starting the communication (data exchange) between the pump and the transmitter. The sensor itself works all the time since it has been connected to the transmitter.

Sequence of events following transmitter connection to the sensor and sensor start is displayed on Fig. Start 1.

Fig. Start 1.    Sequence of sensor start events

Case:
a)   sensor is started immediately after it is connected to the transmitter
calibration is requested 2 hours after the transmitter connection
ISIG data is collected since the moment of the transmitter connection
b)   sensor is started later but earlier than 2 hours after the transmitter connection
calibration is requested 2 hours after the transmitter connection
ISIG data is collected since 40 minutes before the sensor start or since the transmitter connection depending on what comes later
c)   sensor is started more than 2 hours after the transmitter connection
calibration is requested in less than 5 minutes
ISIG data is collected since 40 minutes before the sensor start

If the sensor is started without the transmitter connection, the calibration is requested in less than 5 minutes and ISIG data is collected since the sensor start.

The pump software does not consider the gap between the transmitter connection and sensor start when calculating time of the next calibration request. This information is displayed as Next Cal value on the SENSOR STATUS screen and in various information windows during the process of sensor starting. These values are higher than the real ones except in the case when the sensor is started immediately after the transmitter connection.
