Current-loop measurement specifications

The data logger makes current-loop measurements by measuring across a current-sense resistor associated with the RS-485 resistive ground terminal.

NOTE:

Resistance to ground input for non-isolated 0-20 mA and 4-20 mA current loop measurements is available in CR6 data loggers with serial numbers 7502 and greater.
