a reference. A 20mA input should be around 5500 and 4mA around 1100. If the A/D numbers are not in this
range check input device.
The MAX and LOW calibration inputs are for telling the controller what to display for a 20mA input and a 4mA
input. For example if the input is a drum level sensor monitoring a 55 gallon drum the value for MAX should
be 55 and LOW should be 0. The controller then displays a number automatically ranging between 55 and
0 based on the input value. The units of measure (gallons for example) is set in the Customize menu from
the Home page.
OFFSET - Changes the current displayed value of the 4-20mA input reading to allow for a manual 1pt
calibration of the displayed value.
FACTORY DEFAULT - If the 20mA or 4mA calibration has been incorrectly set (not at 4 or 20) this will reset
the settings back to a factory value for 4 and 20.
