If you intend to use the Power Supply with your RLC
Bridge, proceed to “Power Switch and Connector
Wiring.” If you did not purchase the power supply
and intend to use batteries only, disregard the follow-
ing steps and proceed to “Battery Only Wiring” on
Page 28. NOTE: You will need the leftover black, red,
and green wires to modify your unit if you purchase
the AC Power Supply later.
You will have a 100 0 (brown-black-brown) resistor
left over at this time. Save it for “Calibration.”
