Multiple Choice

If the assigned exposure time is 80 ms, the actual time must be within which range?

Explanation:
Exposure time accuracy is checked by ensuring the actual exposure time stays within a small percentage of the set time. For 80 ms, a ±5% tolerance means plus or minus 4 ms. So the acceptable range is 76 ms to 84 ms. That’s why the correct range is ±4.0 ms. The other options correspond to tighter or looser tolerances (1%, 2%, or 10%), which do not match the standard ±5% window.
