Completion of Analog sensor configuration
•
Perform sensor
User maintenance
settings:
Refer chapter 4.3 for a short description. User Maintenance
holds properties necessary to operate the sensor in accordance with the way the user has chosen to apply
the actual sensor: open
Device Configuration
tab, check
Include User Maintenance
and press
Edit..
in the
User Maintenance heading. Refer Table 6-2 for a description of settings.
•
Perform sensor
System Configuration
if necessary to enable sensor output parameters:
Refer chapter
4.2.3 for a short description: open
Device Configuration
tab, and press
Edit..
in the System Configuration
heading.
–
Statistics can be calculated for each channel/parameter. Type
No Of Samples
for the statistics. Use
minimum 2 samples per recording interval, and maximum 5 samples per 10 seconds recording interval
(e.g max 30 samples per 1 minute recording interval). The sensor warm up time may reduce the
maximum samples per recording interval. If time series is enabled (configuration settings) maximum 63
first values will be available for readout.
–
Check desired output:
Average
,
MinMax
and
TimeSeries
. The latter will include statistics into the
recorded dataset.
•
Add the sensor to the correct recording group, refer chapter 4.1.1.
Table 6-2 User Maintenance settings for Analog sensor.
