IMPORTANT!
If you have purchased this meter
as part of a “Kit”, the meter flange base is drilled
with 4 holes. This allows the meter to be used
with 300 and 700 series pumps. Line the meter
bracket up for installation and insert the bolts in the
two holes that align with the corresponding holes
on the pump outlet. Once the meter bracket is
bolted securely in place install the two plugs in the
holes that were not used to prevent moisture from
entering them.
Meter Calibration
Meter calibration is required upon installation, after disassembly, after significant wear,
or when dispensing a different viscosity fluid. Calibration must be done between 6 and
40 GPM (23 and 151 LPM). Meter calibration can be easily changed by following the
calibration procedure. A container of KNOWN volume will be needed for the calibration
procedure. For the 900 series digital meter, a five gallon container or larger (or a 20 liter
container or larger) should be used.
Procedure for Meter Calibration
Unit of measure and calibration is configured using a 3-step process.
1. Select the desired unit of measure
2. Fill a container with a known volume using the desired fluid.
3. Enter the amount of fluid dispensed.
Prior to calibration, the unit must be placed in calibration mode. Press and hold the TOTAL
and CAL buttons for 5 seconds to enter Calibration Mode.
IMPORTANT! When calibrating, the totalizers will not increase in value.
1. The unit will default to the last unit of
measure used.
2. Press and release the TOTAL button
to toggle through the available units of
measure.
3. Press and hold the CAL button for 2
seconds to move to the next step.
4. If the meter is left untouched for 2 minutes
or the RESET button is pressed, the unit
will automatically exit Calibration Mode
and ignore any changes in volume.
Totalizer
IMPORTANT! Dispensing into a container with a known volume allows the unit
to automatically calculate the internal scaling value to compensate for fluid
viscosities and the system flow rate.
5. CAL 2 will be displayed.
6. Begin dispensing fluid into the container.
7. FILL will begin to blink after fluid flow is detected.
8. Dispense the desired amount fluid; stop flow as soon as desired level is reached.
9. Press and hold the CAL button for 2 seconds to move to the next step.
IMPORTANT!
If left untouched for 2 minutes, or the RESET button is pressed,
the meter will exit Calibration Mode and any dispensed fluid will be ignored.
