4 PRELIMINARY SETUP FOR USE

For a correct display of data regarding treatment, some preliminary set ups are necessary when installing DigiWolf on farming machines.

4.1 Calibration

Rate reading may not be correct due to different system congurations (tubes, valve, etc.). Therefore, we recommend to make

a spray test; in case the measured value is different from the real one, perform an automatic calibration procedure or manually

calculate owrate constant.

4.1.1 Automatic calibration

Make a quantity of liquid previously measured or that can be measured with another system go through the owmeter. The greater the amount of

liquid used to perform the calibration procedure, the more accurate the calibration.

End reading

0.0 l/min

2) Access Automatic calibration menu (Setup menu > Calibration > Auto calibra-

tion). Once inside the menu, the device is ready to start measuring without

any further controls.

3) Make the liquid go through the system. The display will start to show the incre-

asing value of the measured quantity of liquid. Once liquid passage has nished,

the value on the display will not change any more.

At this point, press OK. In the lower part of the display, the message Stabi-

lization will come up and the device will show the screen on the side.

4) Using the keys, enter the values of the liquid quantity previously measured:

A) Press to toggle from one digit to another

B) Press in succession to modify the value of the digit highlighted by the cursor

C) Press to complete calibration procedure, or D) Press for 1 sec. to cancel calibration procedure.

If, after starting calibration, the device does not sense any ow passage (and the display remains in 0), press OK to exit the calibration

procedure without saving.

If the device continues to sense the liquid ow after pressing OK, after a few seconds the error message Stop flow!will be displayed.

Once the ow has been interrupted, the reading will stabilize as by standard procedure.
