Resistive load measurement system

摘要

An improved system for determining the value of a resistive load is provided. The system includes: a reference voltage source; a reference resistor of known value having a first and second terminal, the first terminal connected to the reference voltage source and the second terminal connected to the resistive load; and a software program stored in a control unit connected to the first and second terminal, the control unit operative to read a value of the reference voltage source and a voltage at the second terminal of the predetermined reference resistor and to calculate the value of the resistive load as a function of the readings of the reference voltage source and the second terminal voltages.
