A001 analog channel input
±
10V (4~20ma) analog, playback displays the rudder blade angle,
-10V (4mA) corresponding to the left 35 ° , 10V (20mA) corresponding to the right
35°
. Unit is "
°
" .
Input -10 in calibration point1, input -35 in calibration point1 value .
Input 10 in calibration point2, input 35 in calibration point2 value .
In an ideal situation, the playback interface will be in accordance with the acquisition of the value and
the four points of the linear relationship between the received analog conversion to physical quantity
for playback.
Note
：
Two sets of data must be filled to be able to correct the real analog conversion, otherwise the
actual values displayed by default to 0.
As shown below, two group A001 respectively (-10, -35), (10,35).
