2. A Good Simulator is Superior to Shunt Cal • A simulator is not strain sensitive. • Resistor ratios are less temperature sensitive. • Thermal emf errors are minimized by design. • Symmetrical shunting produces less common mode error. • Provides specific and convenient mV/ V values. • Provides a true zero output. • Has no toggle. • Shunt resistor doesn’t get lost. • A calibration history can be maintained. 4
3. Shunt Cal has some advantages • Low cost. • The bridge circuit is already there. • Need to make and break cable connections can be avoided. • Can be applied conveniently and at any time and during test programs. 5
