Recalibration
Program the BW100 as follows: P390 = 1
P391 = 11.6
P392 = -14.3
P393 = 23.2
P394 = 10.5
P395 = 34.7
P396 = -8
Often only one point of compensation is required, usually at a low load value. In the prior
example, if compensation was only required at 11.6 kg/m, the programming could be as
follows. Compensation is optimized by establishing the next load value that agrees with
the material test, hence where compensation is zero and entering it as the next
compensation point.
P390 = 1
P391 = 11.6
P392 = -14.3
P393 = 23.2
P394 = 0
P395 = 34.7
P396 = 0
