Recalibration
Program the SF 500 as follows:
Parameter Function
P390 = 1 linearization ON
P391-01 = 30 point 1, rate
P391-02 = 60 point 2, rate
P391-03 = 90 point 3, rate
P391-04 = 120 point 4, rate
P391-05 = 150 point 5, rate
P392-01 = - 10.7 point 1, compensation
P392-02 = 11.1 point 2, compensation
P392-03 = - 5.1 point 3, compensation
P392-04 = 8.7 point 4, compensation
P392-05 = -6.0 point 5, compensation
Note: Often only one point of compensation is required, usually at a low rate
value. In the prior example, if compensation was only required at 30 t/h, program
the following parameters. Optimize compensation by establishing the next rate
value that agrees with the material test, the compensation is zero and is entered
as the next compensation point.

P391-01 = 30 point 1, rate
P391-02 = 90 point 2, rate

P392-02 = 0 point 2, compensation
