2.6 Load/Save button:
Saving measurements:
Pressing and holding the
Load/Save button
(Save >2 sec.) allows a measurement to
be saved to the internal memory, and assigns a consecutive sequence number (starting
with 001) to it. Every time the button is pressed and held, the current value is saved
under the next sequence number.
If several measurements have been saved, then pressing the Load button briefly allows
sequence number 001 to be displayed (001 appears at the bottom of the display).
The user can jump to the next sequence number by pressing the λ button (orange arrow
up), and to the previous sequence number by pressing the REF button (orange arrow
down).
Entries can be deleted by pressing the dBm/dB/mW button (labelled with DELETE above
the button).
