If you press the button longer, it increments the next displayed digit of higher significance.
This procedure can be used for fast coarse setting over a wide numerical range. For the
fine adjustment, release the [↑] or [↓] button again. Then press the button again.

during this time.
It is possible to read data at any time, e.g. measured values.
Note

minutes to pass following the pressing of a button, the setting is
saved and the measured
-value display is returned to automatically.
