Program the BW500 as follows:
Parameter
P390 = 1
P391-01 = 6.94
P391-02 = 13.89
P391-03 = 20.83
P391-04 = 27.78
P391-05 = 34.72
P392-01 = - 10.7
P392-02 = 11. 1
P392-03 = - 5.1
P392-04 = 8.7
P392-05 = -6.0
Often only one point of compensation is required, usually at a low load

value. In the prior example, if compensation was only required at 6.94 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
P391-01 = 6.94
P391-02 = 20.00
P392-01 = -10.7
P392-02 = 0
