The equations used to scale the Auxiliary Analog Input 1 signal are given by:
MP-162 EU = SS_AIN1 * MP-164 + SI_AIN1
written with parameter text:
AI1 EU = SS_AIN1 * AI1 Signal + SI_AIN1
where
SS_AIN1 = CP-284 - CP-282 is the Scaling Slope
CP-283 - CP-281
written with parameter text:
SS_AIN1 = EU@AI1 RB - EU@AI1 RA
AI1 RB - AI1 RA
SI_AIN1 = CP-282 * CP-283 - CP-284 * CP-281 is the Scaling Intercept
CP-283 - CP-281
written with parameter text:
SI_AIN1 = EU@AI1 RA * AI1 RB - EU@AI1 RB * AI1 RA
AI1 RB - AI1 RA
and AI1 Signal (MP-161) is assumed to be a calibrated value.
