Probe type determines information printed.
Analysis data output
The Analysis Data Output option is intended for transferring test results to a
supervising computer system such as, for example, a PLC system.
Communication specifications.
The data format for Analysis data output consists of nine ASCII characters.
Seven characters show the value in engineering format one character shows
the result of the test, and one character shows line feed (LF).
The character indicating the result of the test is one of the following.
