Full-bridge measurement

Up to 16 full-bridge measurements may be multiplexed through the AM16/32B. A problem with making full-bridge measurements with this configuration is that the resistance of the wire and multiplexer relays can cause a voltage drop, reducing the excitation at the bridge. The following section describes a configuration that compensates for this by measuring the excitation at the bridge. See AM16-32B Example B-6 CR1000X load cell measurements.CR1X and Wiring for Load Cells CRBasic Example for the program and wiring diagram, or use Short Cut to create the program. With minor adjustments, the CR1000X program can be used with the CR6, CR3000, CR800 series, CR300 series, or CR1000. This program measures 16 load cell sensors through an AM16/32B. The AM16/32B must be in 4x16 mode.
