The measured value can be displayed in the history memory.

Displaying the current measured values
The standard display shows the currently measured value for R
all other measured values. After 5 min. at the latest the display switches back to the standard display.
ADVICE
The pulse symbol indicates a currently measured value. If this symbol does not appear, the
measurement is still ongoing and the latest valid measured value will be displayed. The symbols '˂' or
'˃' will be displayed additionally to the measured value when a response value has been reached or
violated, or the measured value is below or above the measuring range.
