The analog input of the tool uses a non-differential input. Any change in the current
of the common grounding connector may cause an interference signal to the analog input.
It is important to know that there will be a voltage drop on the ground line and inside the
connector.
To clarify the ease of using analog inputs, here are some simple examples:
The above figure is connected to the unit when the user output is also a single-ended
output analog signal.
The above figure is the connection with the unit when the analog output of the user
output is differential output. The use of the sensor with differential output is also
relatively simple and straightforward. Simply connect the negative terminal to GND (0V)
using a terminal strip, and the differential sensor works the same way as a
non-differential sensor.
