Note The operation of the individual measurement, which is initiated via
the external input, can be controlled via the process channel, see
section "6.3.2 Start single measurement via process channel". If no
control is done via the process channel, then the measurement
operation must be controlled by the signal "ENABLE", see section
"6.5.2 Signal ENABLE".
Note Only for FE material (not for NF and LM): If several measurements
are executed consecutively, the measuring operation time should
not exceed 10 seconds. It is advisable to keep a recovery time of
at least twice the measuring operation time.
Example:
10 measurements within 1 second, then 2 seconds of recovering
time. If the recovery time is less than twice the measuring time, the
sensor will warm up and the measuring value will drift.
