6.3.3 Measurement Start / Stop
External control is different for single measurement and continuous measurement. If the sequencer
mode is used, the signals 0-1-2-sheet will be formed as summary output
(For details refer to chapter 6.2.1).
6.3.3.1 Single measurement
The measurement result remains frozen until a new action is initiated.

Note In the relay output version the status of the outputs appears delayed
(<10 ms) due to the switching time of the relays.
Note
High Level at the outputs means relay closed respectively opto
coupler low resistant. Low Level at the outputs means relay open
respectively opto coupler high resistant.
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.
