18. Where May the <strong>Shunt</strong> Resistor Be Located ? a. Internal to a transducer or permanently wired to a bridge circuit. • Resistor tolerance not important. • Resistor should have low temperature coefficient of resistance (TCR). 32
. Internal to an Instrument. • Low resistor tolerance is important unless a bridge and specific instrument are always used together. • TCR should be low. HRBSC 9840 These high end instruments have 0.01% Low TCR Internal <strong>Shunt</strong> Cal Resistors in two different values. Instruments may be substituted without significant error. 33
