Weighing instrument LZXL-20000AL.

The XL-2000AL controller has the following main functions:
The panel keyboard is set for parameter setting and range calibration.
It has the function of display weight zero.
¨ instrument faults, the operation error
4~20mA analog output can set the corresponding weight value of 4mA and 20mA current output.
The control output of low, medium and high 3-channel fixed value can be set to arbitrary control value and buffer value.
