Differential voltage measurement
Typical differential voltage measurement connection shows a typical connection for differential voltage measurements. Using this method, a data logger can make up to 32 differential voltage measurements through a multiplexer.
Refer to the following downloadable program examples and Wiring for differential voltage measurements CRBasic example:
-
Example B-3: CR300 differential measurements with the AM16/32B
-
Example B-4: CR1000X differential measurements with the AM16/32B
-
Wiring for differential voltage measurements CRBasic example: Provides the programs and wiring diagrams
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 2x32 mode. View the program in the CRBasic Editor.
U terminals are only available on the CR6 data logger.
These programs use arrays for multipliers and offsets. This allows individual adjustment of the multiplier and offset for each sensor. For example, in this program the third multiplier, 8, and the third offset, 9, would be applied to the third measurement, DiffV(3).
