Activation of the relative display mode
- Display and storage of the reference and
differential values in the unit of the quantity
measured.
- 1st press: activates the relative mode ∆REL
(present value - reference value)
and stores the measured value that will be
used as reference.
- "REF" indicates storage of the reference.
- Subsequent presses: toggles the display
between the measured value and the relative
measurement ∆REL.
