THEORY OF OPERATION Chapter 2
2 - 19
1. Plunger Driver Position Calibration
This is accomplished by using calibration standards to input two drive position locations to
the pump. The software then utilizes these two reference locations to complete the driver
position calibration. With this information, the pump is then able to determine the distance
between the plunger driver and the barrel clamp.
2. Syringe Recognition Calibration
This is accomplished by using calibration standards to input two barrel clamp positions to
the pump. The software then utilizes these two reference positions to complete the syringe
recognition calibration. With this information, the pump is then able to recognize syringe
barrel diameters as part of its syringe recognition feature.
3. Pressure Sensor Calibration
This is accomplished by providing input to the pump while hanging a 10 lb. calibration
standard on the plunger driver then providing similar input when there is no load on the
plunger driver. The software then utilizes these two reference points to complete the
pressure sensor calibration. With this information, the pump is then able to recognize
pressure values applied to the plunger driver.
4. VB_SENSE Calibration
This is accomplished by using a variable power supply to provide two references points to
the pump at 7.5 V and 5.5 V. The software then utilizes these two reference points to
complete the VB_SENSE calibration. With this information, the pump is then able to
recognize battery voltage values.
2.3.1.2.3 Aborting a Calibration Sequence
For each sensor calibration sequence, new settings are not saved until UPDATING is
displayed. Turning off the pump prior to the UPDATING display aborts the sequence and
leaves the original settings unchanged.
CAUTION
To prevent corruption of the calibration data, do not turn off the pump
or press any key while UPDATING is being displayed.
2.3.1.2.4 LED Indications During Calibration
At the beginning and end of each sensor calibration sequence (before and after the portion
of the sequence in which the standards are read), the LEDs indicate the following:
1. The ALERT LED is on when the pump is vertical.
