Technician A says a that a voltmeter can be used to monitor the output signal of an optical sensor. Technician B says that optic
al sensors should be tested with an oscilloscope because of the sensor's speed. Which technician is correct? A. Technician A only
B. Technician B only
C. Both technicians A and B
D. Neither technician A nor B
An oscilloscope can be used to check the output signal of an optical sensor. The oscilloscope has the functioning of viewing the results in the form of waveform and its time scale settings can be altered to meet the requirements of the results.
A voltmeter cannot be <u>directly</u> used to monitor the output signal of an optical sensor. But a <u>digital multi-meter</u> can be used to check an optical sensor if the digital multi-meter is set on AC - Volt reading mode.
