0.0% Complete A red light is used to warn employees of a plant when the sewer pit gets too full. The red light is attached to a digital control panel. The light is supposed to go off when the pit is half full. The light has been flickering on and off one day, even though the pit is actually a little less than half full. In investigating the problem, you see that a level transmitter sends a 0-10 volt signal to the control panel. The control panel converts the signal to a digital reading using a 4-bit converter. The digital result is used to light the alarm. You check the output of the level transmitter, and it is about 4.7 volts. Which of the following might be causing the alarm light to come on? A. The level transmitter is faulty. B. The A/D is miscalibrated. C. The A/D reads 4.7 V as 5.0 V because of rounding error. D. Nothing, the light should be on at 4.7 volts. ​
