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 OIL CELL:
Remove container from its lodgings, Make sure that the container plate is free and unimpeded
 Select Min verify that the value in the textbox Min is 0 ml (otherwise use the keypad)
then press ENTER, to confirm press Min
 Put in the slot of the container a known reference weight ( 500 grams)
 Use keys 0 through 9 to type in the value in ml by adding 4%, in this case 520 (for
example, if the weight is 100 grams write 104 ml), select Max then press ENTER
 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 85 g); select Tare then press ENTER
 Verify the correct reading of the scale, adding and removing a reference weight (100g
correspond to 104ml).
 Press ENTER to exit, then press ESC to exit from CALIBRATION MENU and save.
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 520 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.
