If you hold the button down for a longer period, it counts to the next highest displayed
point. This process allows for a rough adjustment over a wide range. For fine adjustment,
use the <UP> or <DOWN> button again. Press the button again.
Violations of the measured value limits are displayed on the digital display with
time.
However, it is possible to read data, e.g. measured values, at any time.
Note
If more than 2 minutes has passed since the last button was pressed, the setting is
automatically saved and the device automatically returns to the measured value display.
