0-20 mA/4-20 mA burnout/4-20 mA/0-10 V/±10 V Mode
Burnout Value (only for 4-20 mA burnout mode): The 4–20 mA burnout mode is shown in the diagram
below.
The Burnout Value (default = 2 mA) is definable (unit: mA, 0.000 to 4.000). When input values are in the
burnout range, raw data will register as 0000h to indicate that the analog input has burned out. The definition
of raw data can be found in the table below.

1
st
Point Measured Value: The 1
st
point value in the range of channel mode to be scaled to the 1st Point
Scaled Value (unit: mA, 4.000 to 20.000).
2
nd
Point Measured Value: The 2
nd
point value in the range of channel mode to be scaled to the 2nd Point
Scaled Value (unit: mA, 4.000 to 20.000).
Unit: The unit of the measured value.
