The equations used to scale the Auxiliary Analog Input 1 signal are given by:
MP-162 EU = SS_AIN2 * MP-161 + SI_AIN2
written with parameter text:
AI2 EU = SS_AIN2 * AI2 Signal + SI_AIN2
where
SS_AIN2 = CP-289 - CP-287 is the Scaling Slope
CP-288 - CP-286
written with parameter text:
SS_AIN2 = EU@AI2 RB - EU@AI2 RA
AI2 RB - AI2 RA
SI_AIN2 = CP-282 * CP-283 - CP-284 * CP-281 is the Scaling Intercept
CP-283 - CP-281
written with parameter text:
SI_AIN2 = EU@AI2 RA * AI2 RB - EU@AI2 RB * AI2 RA
AI2 RB - AI2 RA
and AI2 Signal (MP-164) is assumed to be a calibrated value.
