Viper Pro Installation & Operation Manual
To verify the flow meter calibration:
1.
Fill the applicator tank with a predetermined volume of liquid (i.e. 250 gallons [946 L]).
Important:
Do not rely on graduation markings/numbers molded into the applicator tank.
1.
On the field computer Home screen, touch the Tools Menu icon.
2.
Select the Product Control icon from the System menu.
3.
On the Product Control Configuration screen, touch the Volume/Area Settings button.
4.
Use the on-screen keypad to enter a value of 0 and touch the Accept icon.
5.
Empty the applicator tank under normal operating conditions.
6.
Return to the Total Volume displayed on the field computer and read the new value. The total volume value
should match the known volume (± 3%) used to fill the applicator tank.
7.
If the total volume value displayed differs from the known volume by greater than 3%, use the following
formula
Where MC = the Meter Cal value used during the test, Vm = the Volume measured by the field computer,
Vk = the known Volume in the applicator tank and CMC = the Corrected Meter Cal.
For Example:
A set meter cal of 720 [190] is used to dispense 250 gallons [946 L] through the flow meter. At the end of the
test, the field computer reads a measured volume of 260 gallons [984 L]:
or
Therefore, the corrected meter cal is 749 [198].
8.
Enter the corrected meter cal value before resuming application.
