Precision Shunt Calibration Resistors

This diagram shows the connection of the precision internal shunt resistors.

The back panel switch (shown to the left of the two resistors) selects between 30 KΩ

and 60 KΩ.

The shunt check relay (shown to the right of the two resistors) connects the selected

resistor between the Excite High and the Cell Output High.
