Single-ended voltage measurement

Typical single-ended voltage measurement connection shows a typical connection for single-ended voltage measurements. Using this method, a data logger can make up to 48 single-ended voltage measurements through a multiplexer.

Refer to the following downloadable example programs and Wiring for single-ended voltage measurements CRBasic example:

Alternatively, use Short Cut to create the program. With minor adjustments, the CR1000X program can be used with the CR6, CR3000, CR800-series, or CR1000. In either case, the AM16/32B must be in 4x16 mode. View the program in the CRBasic Editor.
