SECTION 2 - OPERATION
Load Cell Calibration
NOTE
: Displays shown here are in full grams. MB, 100 and 200 series models are in 1/10 grams, with a decimal.
If your load cells already display a weight close to zero, plus or minus 10 grams, you may skip this section and go directly to:
TURNING ON OUTPUTS (next page).
If your unit DOES NOT display an acceptable weight, you should recalibrate them, that is reset your ZERO weight, at this
time.
To do so:
BE SURE the weigh bin is EMPTY.
BE SURE the load cell plug is plugged into the side of the controller.
BE SURE the weigh bin is resting on the load cells freely.
BE SURE the air line to the dump valve is connected, as it would be during normal operation. A disconnected air line adds
weight.
BE SURE the load cells and bin are not jammed in any way. To test for this see that a light touch on the bin causes the
display to change. When the pressure is removed the display must return to exactly where it was, plus or minus 1 gram.
If this does not happen, something is touching something and the bin is not entirely free to move. Check EVERYTHING
around the bin.
LOAD CELL CALIBRATION:
The sequence of keystrokes is as follows
:
Load Cell Zero Calibration Keypad Sequence:
Press

Press
Display will say: (P x)
Press
Display will say: (-- WAIT --)
Followed by: (P 0)
Press
Display will say: ( x)
The ZERO point of the load cells is now set properly. FULL weight calibration may also be done at this time, however, it
probably is NOT NECESSARY. When load cell readings shift due to rough handling, the entire range of readings from
ZERO to FULL shift together. The ZERO weight calibration routine resets the full range of the cells and, therefore, corrects
FULL weight readings as well. For information on FULL weight calibration, see RECALIBRATION OF LOAD CELLS.
