Procedure 2 (Automatic)
1. Place the controller in Calibration Mode - select
automatic procedure.
2. Set the desired flow rate. The pre-set flow rate
set point for the selected CHANNEL is based
on the Total Flow Rate and Ratio for the GUN,
as stored in the JOB, since calibration should
always be performed at the normal flow rate for
the CHANNEL. The operator may override this
value, if desired.
3. Set the desired time to collect fluid. The preset
time for the selected CHANNEL is based on the
desired flow rate for the CHANNEL so that 200 cc
of material will be dispensed. The operator may
override this value, if desired.
4. Make sure that the applicator is triggeredOFF and
any calibration valves are closed. Also make sure
that the fluid has been loaded up to the point at
which the fluid sample is to be taken (GUN output
or calibration valve).
5. Place a graduated container at the place of fluid
collection (GUN or calibration valve).
6. Trigger the GUN ON (manually or automatic) or
open the calibration valve.
7. Select "Start Cal".
8. Collect and measure the fluid. Fluid flow will stop
once the timer has expired.
Calibration by Weight
If calibrated by volume, it is not necessary to calibrate
by weight.
Required:
• Specific gravity of material
• Digital scale, accurate to 0.10 grams
1. Weigh the empty beaker and record the tare weight
for later calculations.
2. Enter the calibration mode for the desired CHANNEL.
3. Perform the desired collection procedure above.
4. Weigh the fluid in the beaker and subtract the beaker
tare weight to get the net weight of the fluid collected.
5. Entered the measured weight.
NOTE
†
It is not important that fluid be flowing, or triggered
ON, for the entire calibration time. The calibration
procedure is based only on the volume of fluid that
was registered. Automatic mode simply supplies a
convenient means to calibrate close to specific flow
rate and for an approximate amount of time.
9. Enter the measured amount.
10. Accept or reject the new Pulses Per Liter number
that the controller calculated. The flow meter
calibration will automatically be updated.
NOTE
†
An unassigned CHANNEL cannot be calibrated.
The CHANNEL must be assigned to a Gun and the
Gun must be configured.
†
If the weight method is used, the specific gravity
of the material must be entered.
†
The new value for pulses per liter will be automat-
ically calculated and updated.
†
Repeating the calibration procedure is highly rec-
ommended to ensure it was performed satisfactorily.
