7. Edlog Program Examples

7.1 CR10(X), CR510, and CR500 Examples

7.1.1 Instruction 6 (4-Wire Full Bridge Measurement)

7.1.1.1 Wiring

Datalogger CS420-L/CS425-L

Excitation E1 Red (Supply +)

Input H1 Yellow (Output +)

Input L1 Blue (Output -)

An. Ground AG White (Supply -)

G Clear (Shield)

The orange and black wires are not used and the ends of these wires should be

taped to prevent shorting.
