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 K
Ω 
and 60 K
Ω.   
 
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.
