9900 Transmitter
Volume Calibration Procedure
1. Press ENTER to start the volumetric calibration period.
The 9900 starts counting pulses from the
fl
ow sensor.
2. Press ENTER to stop the volumetric calibration period.
The 9900 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 Flow K-Factor.
4. The 9900 displays the newly calculated K-Factor for your reference.
(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 INPUT menu.
Rate Calibration Procedure
1. Use
▲
,
▼
and
►
to set the
fl
ow rate in the
fl
ashing display to match the reference meter.
Press ENTER when completed.
2. The 9900 displays the newly calculated K-Factor for your reference.
(If the calculated K-Factor is less than 0.0001 or greater than 999999 (out of range at
either extreme), the 9900 displays "ERROR NEW KF OUT OF RANGE" and returns to
RATE CAL. If
fl
ow is too low to accurately calibrate, the 9900 displays "ERROR FLOW
RATE TOO LOW and returns to RATE CAL.
3. 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 INPUT menu.
Calibration Procedure - Flow
Select RATE CALIBRATION to match the dynamic
fl
ow rate to an external reference.
Entering a rate will modify the existing K-Factor.
Select VOLUME CALIBRATION if the
fl
ow rate can be determined by
fi
lling a vessel
of known volume. The 9900 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 new K-Factor.
