6.3.4 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“).
6.3.4.1 Single measurement
The measurement result remains frozen until a new action is initiated.

: The system reaction time is the time required by the unit in order to issue the result to the
output after the signal "Measurement Start" has been recognized
(For details refer to chapter 2.4).
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 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.
