Question 3 of 9
A photo sensor datasheet states that the sourcing current output is <250 mA.
1. What is the proper dial setting to measure the current output of the sensor if the sensor is energized?
2. If the sensor is de-energized, what is the proper dial setting for measurement?Reveal answer1. For the on-state current, the 10A DC setting (middle right side of the dial) is most appropriate. 250 mA may destroy the fuse for the mA setting.
Depending on the load (input module) resistance, the actual current may be much less than 250 mA.2. The off-state leakage current should be very, very small. Use the 200u dial setting.
If the value reads 200 uA, move the next highest setting, but verify with a datasheet for the sensor. 200 microamps when switched off is abnormally high and may indicate a defective sensor.
