Figure 8 Software Scaling

Here is a simple example of software scaling

Command Description

Sample (digitize) CLT_CH and store

; Store digitized Cantilever CH.

ADD CLT CH_OFSET to CLT_CH parameter

; Cantilever CH_OFSET is the zero correction
constant.

Multiply offset corrected CLT CH parameter by CLT
CHGAIN

; This is the composite tension feedback


Note that sometimes, over-sampling and filtering can be used to generate a robust tension feedback
parameter despite brief disturbances (either mechanical or electrical).
