(a) Each differential channel can be configured as 2 single-ended channels; expandable with multiplexers.
(b) Precision 2:1 and 10:1 voltage dividers are available to extend these ranges.
(c) One measurement with data transfer without interruption.
(d) Switch closure, high frequency square wave, or low-level AC sine wave.
(e) Expansion peripherals are available, see SDM literature.
(f) Port C2/P3 is input only and can be software configured as an SDI-12 port, a binary input, or as a switch closure counter (40 Hz maximum).
(g) All excitation and CAO (Continuous Analog Output) channels can be individually programmed as outputs by the end-user.
(h) CAO channels can be programmed to hold a constant value or vary with the magnitude of a measurement.
(i) 0 V low, 5 V high; the CR510, CR10X, and CR23X have ports that are configurable for interrupt subroutines.
