Procedure 2 (Automatic)
1. Place the controller in Calibration Mode - se-
lect 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 over-
ride this value, if desired.
3. Set the desired time to collect fluid. The pre-
set 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 oper-
ator may override this value, if desired.
4. Make sure that the applicator is triggered
OFF 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.
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.
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 en-
tered.
The new value for pulses per liter will
be automatically calculated and updated.
Repeating the calibration procedure
is highly recommended to ensure it was
performed satisfactorily.
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 reg-
istered. Automatic mode simply supplies
a convenient means to calibrate close to
specific flow rate and for an approximate
amount of time.
