USED OIL CELL
If you have not changed the load cell or motherboard you can restore the calibration (refer to
RESTORE CALIBRATION paragraph)
From CALIBRATION, select USED OIL CELL:

Remove container from its lodgings, taking care not to exert pressure on the scale,
Select Min verify that the value in the textbox Min is 0 ml (otherwise use the keypad)
then press OK to confirm Min.

Put in the slot of the container a known weight that varies from 100 to 200 grams

Use keys 0 through 9 to type in the value in ml by adding 4% (for example, if the weight
is 100 grams write 104 ml), then press OK to confirm MAX.

Replace the empty container in place and ensure that the amount is 0 ml, otherwise
modify the value of the tare, use keys 0 through 9 to type in the value of the tare
(usually approximately 150g); then press OK to confirm Tare

Verify the correct reading of the scale, adding and removing a reference weight (100g
correspond to 104ml).
Switch off the machine and disconnect it from the electrical supply.
NOTE: To get an accurate value of the tare this should be weighed with the empty oil container
mounted on the plate (tare value can vary from a few grams, depending on the positioning of
the oil container and the tubing connected to it). Insert 150 g does not compromise the correct
functioning of the cell but simply move the value "0" reference distorting the availability of a few
grams of oil present in the container.
