7.5 Measured values and history memory
Only R is permanently displayed (standard display). For all other measure-
F
ments, the display returns to the standard display after at least 5 min. The pul-
se symbol indicates a current reading. In the absence of this symbol, the
measurement is still read and only the last valid measured value is displayed.
The symbol "<" or ">" is displayed with the measured value when a response
value has been reached or exceeded, or if the measuring range is outside the
set parameters.
