DESCRIPTION
The Set Data Format (
F
) command configures the input and output data format for data transmissions with the
unit, and requires two arguments. The first argument
engr
refers to the specific Engineering Units if applicable,
and the second argument
format
refers to the reading format.
The following tables list the valid data input and output formats for Engineering Units, Binary, and Counts.
