10.5. Analog Output Module
The 495 R module expands the functionality of the MW-01-A converter by an
analog output, 4-20 mA, and a voltage output, 0-10 V. The module is intended
to be mounted inside the MW-01-A. The 495R module is a passive module.
The MW-01-A converter's housing features a cable gland through which a
3-metre cable 6x0.34 mm2 is fed, which cable is terminated with isolated wires.

BY DEFAULT, SET THE ANALOG OUTPUT MODULE TO 4-20 mA MODE.
Analog output must be calibrated (adjusted); using P1 potentiometer set the
correct offset (e.g., for 4 - 20 mA output, adjust current so that for 0 kg
indication it is precisely 4 mA). In the case of remaining operation modes
proceed analogously.
