is continuously indicated on the display (standard display). All other measuring value
displays switch to the standard display after a maximum of 5 minutes. The pulse symbol
indicates a current measured value. If this symbol does not appear, the measurement is
still running 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 exceeds the measuring range.
