R8C Measures Negative Voltages
The author had to design a monitor circuit for the so-called Hercules Table (an electrically movable platform) at the
The movement of the platform (up/down) is done with a DC voltage between +8 V and –8 V, where the magnitude of the voltage determines the speed and the polarity determines the direction. There are also a number of fixed voltages that need to be monitored.
