The equations used to scale the Auxiliary Analog output signal are given by:
MP-167 volts (or mA) = SS_AO * MP/CP (selected by CP-290) + SI_AO
written with parameter text:
AO Signal = SS_AO * MP/CP (selected by CP-290) + SI_AO
where
SS_AO = CP-294 - CP-292 volts (or mA) is the Scaling Slope
CP-295 - CP-293 in selected MP/CP units
written with parameter text:
SS_AO = AO RB - AO RA A
Val@AO RB - Val@AO RA
SI_AO = CP-292 * CP-295 - CP-294 * CP-293 is the Scaling Intercept
CP-295 - CP-293
written with parameter text:
SI_AO = AO RA * Val@AO RB - AO RB * Val@AO RA
Val@AO RB - Val@AO RA
The AO is assumed calibrated so that the actual voltage (or current) is reflected by AO Signal (MP-167).
