E / P SCHEMATIC
The input impedance will vary depending upon the potentiometer setting of the “SPAN (RV1)”, ( SEE FIG. 2 ). The I/P circuit design
consists of a resistor and potentiometer in parallel with the coil/flexure. The E/P circuit utilizes a potentiometer in series with the
coil/flexure. The following are some of the nominal impedences that would be measured across the signal leads of the average
calibrated transducer. These values are helpful when determining power requirements and for trouble-shooting.
