Calibration
Volume Calibration Procedure
1. Press ENTER to start the volumetric calibration period. The 9900
activates the BATCH Relay and starts counting pulses from the
fl ow sensor.
2. Press ENTER to stop the volumetric calibration period. The 9900
deactivates the BATCH Relay and stops counting pulses from the
fl ow sensor.
3. Enter the volume of fl uid known to have fl owed past the sensor
during the volumetric calibration period. This will modify the
existing K-Factor.
4. The 9900 displays the newly calculated K-Factor for your reference.
NOTE: If the calculated K-Factor is less than 0.0001 or greater than
999999 (out of range at either extreme), the 9900 displays "ERROR
VOLUME TOO HIGH" (or LOW) and returns to VOLUME CAL.
5. Press ENTER to accept the new K-Factor (9900 displays "SAVING")
or press ▲+▼ keys simultaneously to escape without saving and
return to Enter Volume.
NOTE:
• You may enter your own calculated K-Factor in the CAL menu.
• In Simple Mode, the calculated K-Factor will replace the current
K-Factor.
• In Advanced Mode, the calculated K-Factor value will replace the
fi rst K-Factor.
• A K-Factor can be calculated for each batch. Repeat steps 1-5 for
each batch and enter calculated K-Factor for the corresponding batch.
NOTE: In Advanced Mode the Batch Controller has a separate K-Factor
for each stored batch. In Simple Mode the stored batches use a
common K-Factor. If you switch from Simple Mode to Advanced Mode,
the single K-Factor will be copied to the K-Factor for each batch.
If you switch from Advanced Mode to Simple Mode, the K-Factor for
Batch 1 will be copied to the single K-Factor used for all batches.
