Load Cell Balancing C &D
Load cells are now balanced
Balancing the load cells requires a subsequent zero and span recalibration
Balancing six load cell belt scales
For a six load cell belt scale, the six load cells are connected into four inputs. Load cells A, C
and E are connected into inputs A and C; load cells B, D and F are connected into inputs B and
D.
Balancing load cells is still recommended to optimize system accuracy. The balancing needs to
be done twice, once for P295–01 = A and B and then once for P295–02 = C and D.
Three weights that are all very close to the same mass are required.
1. Place one weight at load cell B, one weight at load cell D and one weight at load cell F, all at
the same time.
2. Start the balancing procedure for A and B.
3. Press enter for B.
4. Move the 3 weights to A, C and E.
5. Press enter for A.
Balance for A side and B side is complete.
1. Move all the weights back to B, D and F.
2. Set P295 to C and D.
3. Press enter for D (or B, depending on software revision).
4. Move the 3 weights again to A, C and E.
5. Press enter for C (or A, depending on software revision).
Balance for C and D is complete. Remove the weights and perform zero calibrations.
Note
After balancing is complete, applying a weight
on A or B side should not result in the digital
count values from PAR 943 being out by no more than a difference of 100.
