PROCEDURE TO RE-CALIBRATE FLOW
METER:
1. Enter a METER CAL number of 10 [38] in key
labeled:
METER
CAL
5
2. Enter a TOTAL VOLUME of 0 in key
labeled:
TOTAL
VOLUME
3. Switch OFF Boom 2 and Boom 3.
4. Remove Boom 1 hose at boom connection
and place the hose in a 5 gallon [19 liter] container.
5. Switch on Boom 1 and pump exactly 10
gallons [38 liter], two 5 gallon [19 liter] buckets.
6. The readout in TOTAL VOLUME is your new
METER CAL number. (Under normal
circumstances, this number should be within
+/- 3% of the number stamped on the tag on Flow
Meter).
7. Repeat procedure several times to confirm
accuracy. (Always zero out TOTAL VOLUME
display before retesting).
NOTE: for greatest precision, set METER CAL to
100 [378] and pump 100 gallons [378 liters] of
water.
8. Enter correct METER CAL number before
resuming chemical spraying.
An alternate method of calibrating your Flow Meter
is to fill your applicator tank with a pre-determined
amount of liquid. Set your METER CAL to the
number on the tag attached to the Flow Meter.
Then go out and spray until the tank is empty. The
number in the TOTAL VOLUME display should be
the same as the amount you put in the tank. If
not, increase or decrease the METER CAL by the
percentage difference.
PROCEDURE TO TEST SPEED SENSOR TO
CONSOLE CONNECTION:
Disconnect the Speed Sensor Switch Assembly
Cable from the back of the Control Console. See
diagram of Console receptacle in FIG. 9.

VOLTAGE READINGS
10 oclock to 6 oclock (+5 VDC)
10 oclock to 2 oclock (+5 VDC)
1. Record SPEED CAL value
.
2. Enter a SPEED CAL number of 1,000 in key
labeled:
3. Depress key labeled:
4. With small jumper wire (or paper clip), short
between 10 oclock and 6 oclock sockets with a
short - no short motion. This should cause a
speed reading to be displayed in the Console. If
speed reading is displayed, Console power is
confirmed. Therefore, replace Speed Sensor
Switch Assembly.
5. If no speed reading is displayed, refer to
CONSOLE TROUBLESHOOTING, pages 18, 19
and 20.
NOTE: After testing is complete, re-enter correct
SPEED CAL number before spraying.
