5.1.4 Resistors and Inputs Connected in Parallel

Parallel resistance Rp: FX1S = 15k. If resistance Rp is less than the stated value, then add the

Rb value using the Equation 1 calculation.

Alternatively; Current leakage: FX1S = 1.5mA. If the current leakage is greater than the stated

value, then add the Rb value using the equation 2 calculation.
