digital panel meter fluctuation problem
@V_C: well, infact, it mesures the voltage drop on a shunt (if 10A goes through this shunt resistor, the voltage drop is 75mV). So if no current flows through this shunt resistor, the voltage drop is 0V. That makes the meter display 0.00
But in fact, it displays 0.60 and fluctuates around this value.
To simulate 0V, I connect the input (+) to input (-), I think that it should display 0.00 but no.
Thank you E_Design, I'll try your recommendation.
