In Relative Mode, the reading shown is always the difference between the present reading and the stored reference value.
Correct Answer:
True
Explanation:
Relative mode is about measuring change from a known reference. The instrument keeps a stored reference value and, when a new reading is taken, it shows the difference between the current reading and that reference. This delta display makes it easy to see how much the signal has moved since the reference, rather than its absolute level. So the reading shown being the difference between the present reading and the stored reference value is exactly what relative mode does, making this statement true. If you needed the exact, absolute value, you’d use a mode that displays the current reading directly rather than the delta.
