This unit was properly calibrated at the factory to match the load cells that were supplied with it. If
you are going to recalibrate, note the following. The proper sequence is given below.
BE SURE the load cell plug is plugged into the side of the controller.
BE SURE the weigh bin is hanging from 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.)
Air pressure to the line is not necessary.
BE SURE there is nothing touching the weigh bin or air line.
BE SURE the bin is EMPTY when ZEROING the load cells.

ZERO weight calibration must be done before FULL weigh calibration. Since changes in ZERO
weigh will also shift the FULL weigh by the same amount, it may not be necessary to do FULL.

When entering the FULL WEIGHT, BE SURE you know the exact weight (in GRAMS) that you are
adding to the bin. Place weight in the bin, press FULL and then enter the weight in grams.

Enter the EXACT weight in GRAMS that you have placed in the bin. The weight should be close to
the designed full bin weight; (400, 1000, 2000, 4000, 9000, or 18000).
