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 „3.5 Applications examples").

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