Note the following:
• These remote functions will apply only if
the remote controls are enabled through
this I/O Module.
• Lines 4 and 5 control only the desired
range of the span function as described
in Line 2.
• If the digital lines described above are
not connected, the Line 2-related span
function will only select Range 1; it will
not calibrate any other range. However,
the Line 3 function will span or check
ranges as setup in the module's pro-
gramming.
• After calibration, the Analyzer module
will be returned to the range it was op-
erating on previous to calibration.
