High mA
This is the value that represents the maximum analog signal that will be
sent. It is entered in mA (milliamperes). Note the range is nominally 4-20mA,
but it is possible to enter numbers outside this range if the connected device
cannot be calibrated.
Full Scale
This is the maximum process value that will be assigned to the maximum
analog output value. The Full Scale value is entered in engineering units
representing the process value. For example if the analog output function is
set to Feedrate, then this value would be set in units of rate (i.e. lb/min,
kg/min).
Low mA
This is the value that represents the minimum analog signal that will be sent.
It is entered in mA (milliamperes). Note the range is nominally 4-20mA, but it
is possible to enter numbers outside this range if the connected device
cannot be calibrated.
Zero
This is the minimum process value that will be assigned to the minimum
analog output value. The Zero value is entered in engineering units
representing the process value. For example if the analog output function is
set to Feedrate, then this value would be set in units of rate (i.e. lb/min,
kg/min).
