Rcal (shunt) Resistor PF2310 Deflection Estimates

These tables are used to estimate output values from the Ames SDS data
system for various settings of Rcal (shunt) resistors on the Precision Filters
2310 amplifier card.

Maximum value for PF2310 Vout is ±10.24 volts, also input limit of Preston A/D signal converters. In SDS Counts, maximum value is ±32767.

Equation 1: Rcal value (volts) = (gage resistance • exc • gain) / (gage resistance + 2 • rcal resistance) / 2

Equation: Rcal value (volts) = (gage resistance • exc • gain) / (gage resistance + 2 • rcal resistance) / 2

Equation 2: INCAL value (counts) = Rcal value in volts • 3200

Equation: INCAL value (counts) = Rcal value in volts • 3200
