13. Calibration
Volumetric calibration
Select VOLUMETRIC CALIBRATION if the fl ow rate can be
determined by fi lling a vessel of known volume. The 8900 will
count the number of pulses generated as the known volume of
fl uid passes through the sensor, and then use the information to
calculate a K-Factor.
Select to perform volumetric
calibration.
Press ENTER to start the
volumetric calibration period. The
8900 starts counting pulses from
the fl ow sensor.
Press ENTER to stop the
volumetric calibration period. The
8900 stops counting pulses from
the fl ow sensor.
Enter the volume of fl uid known to
have fl owed past the sensor during
the volumetric calibration period.
This will modify the existing Flow
K-Factor.
The calculated K-Factor is less
than 0.0001 or greater than 99999.
Returns to Enter Volume.
Successful volumetric calibration.
Press ENTER to accept the new
K-Factor or press UP-DOWN keys
simultaneously to escape without
saving and return to Enter Volume.
F1 Cal Method:

Rate-based calibration
Select RATE CALIBRATION to match the dynamic fl ow rate to
an external reference. Entering a rate will modify the existing
K-Factor.
Indicates that the fl ow sensor is not
generating any pulses, or pulses
are not detected by the 8900.
Returns to Volumetric Cal.
