Launching
Because this system is designed to allow continuous logging and
transmission of data, once you launch the HOBO U30 station it will always
use the schedule you have selected in HOBOlink.com for logging and
reading out. Any changes you make to the Launch Configuration will take
effect the next time the HOBO U30 Station connects to HOBOlink.com.
Important: Although the HOBO U30 Remote Monitoring System can be
used with HOBOware Pro, it is strongly recommended that
launching be done exclusively through HOBOlink.com. Any
launch that you have set up with HOBOlink.com will override
the launch parameters set with HOBOware Pro.
The following table explains the features available in the Launch
Configuration.
Launch Configuration
Feature
Description
Logging Interval
This is how frequently the HOBO U30 Station
records data measurements.
Sampling Interval
This is how frequently the HOBO U30 Station
makes measurements for a Smart Sensor that
supports measurement averaging. The average
over the logging interval will be logged. Enable this
feature only if you are using one or more of the
following Smart Sensors that support measurement
averaging:
12-bit Temperature S-TMB-M0XX
12-bit 4-20 mA Input Adapter S-CIA-CM14
12-bit Voltage Input Adapter S-VIA-CM14
Photosynthetically Active Radiation (PAR)
S-LIA-M003
Silicon Pyranometer (Solar Radiation)
S-LIB-M003
Barometric
S-BPB-CM50
Wrap Around When
Full
By default, the HOBO U30 Station is set to Wrap
Around When Full. This means logging will
continue once the 512K memory is full, with the
newest measurements overwriting the oldest
measurements, and new data will continue to be
uploaded to HOBOlink. If you wish to stop logging
once the memory is full, and then disable Wrap
Around When Full.
