OMEGA DPU91-BC Batch Controller System
Volume Calibration Procedure
1. Press ENTER to start the volumetric calibration period.
The DPU91 activates the BATCH Relay and starts counting pulses
from the
fl
ow sensor.
2. Press ENTER to stop the volumetric calibration period.
The DPU91 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
DPU91 during the volumetric calibration period.
This will modify the existing K-Factor.
4. The DPU91 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 DPU91 displays
"ERROR VOLUME TOO HIGH" (or LOW) and returns to
VOLUME CAL.
5. Press ENTER to accept the new K-Factor (DPU91 displays
"SAVING") or press

keys simultaneously to escape
without saving and return to Enter Volume.
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.
20. Calibration
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.
