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.
