B.6 Calibration
B.6.1 Calibration Check Programme 1
There are two ways to access the calibration check programme, the first is by
pressing the following key tabs; INFO, SETUP & CAL CHECK. This will calibrate
the product in the bin which was active on the individual INFO screen. The second
is to press the MENU key tab (under the TOT key tab) and then CAL CHECK. The
only difference between these two methods of accessing the calibration
programme is that the first option only allows the calibration to be run on the bin
which was on the INFO screen whereas the second option allows the bin to be
selected on the first screen by using Key I.
The first screen of the calibration programme is shown in Figure 34. This screen
requests the operator to enter the amount of product to be dispensed. This is
done by using the key pad and pressing ENTER. The programme gives the option
to correct the amount to be dispensed. If the number entered is incorrect, use
the keypad and press ENTER. If the number was correct press ENTER to proceed
to the next screen.

The second screen is shown if Figure 35. Pressing ENTER again will start the
product dispensing. The actual amount of product dispensed is based on the
product calibration factor and the gearbox ratio. The instrument calculates the
number of motor revolutions required and then carries this out. Whilst the motor
is running the screen Figure 35 is shown with the weight accumulating.
