Figure 12 Separate DC and AC Coupons Wiring Diagram (CP38)
When using separate DC and AC coupons with the RMU1, an adapter board must be used. This adapter board contains
a precision shunt resistor and provides a terminal block for connections to the coupons, structure and reference cell. The
shunt is a 10 ohm resistor; this shunt resistance must be used in the coupon calculator in the RMU1 configuration
application to obtain correct readings.
