LI5X Process & Temperature Meter Instruction Manual

Scaling the 4-20 mA Analog Output (

Aout

)

The 4-20 mA analog output can be scaled to provide a 4-20 mA signal
for any display range selected.
No equipment is needed to scale the analog output; simply program the
display values to the corresponding mA output signal.
The

Analog Output

menu is used to program:

1. 4-20 mA output based on display values
2. Sensor break value in mA
