Configuring the modules
While Smart Sensors are designed and preconfigured for specific purposes, FlexSmart modules are user-
configurable to accommodate a wide range of Onset and third-party sensors. To take advantage of this adaptability,
HOBOware Pro lets you configure these modules at launch time, or create and save different configurations to be
loaded into the modules whenever needed.
If you connected only Smart Sensors, skip ahead to the next topic, “Launching the logger.”
1. Access the Configure Channel dialog in HOBOware Pro. From the Launch window in HOBOware,
double-click a module name to expand it, then select a module channel and click
Configure.
2. Load an existing configuration, if available. HOBOware Pro may already have a default configuration
for your sensor. Click the
Load button to select an existing configuration for the sensor.
3. Review the loaded configuration, or create a new one. The Configure Channel dialog allows you to
create or change the channel name, scaling parameters, and other items. (Refer to the HOBOware Pro
User’s Guide for details.)
4. Review or set excitation power, if applicable. If this is an Analog module, make sure that the excitation
power settings are correct for the intended sensor.
5. Save the new or changed configuration. Skip this step if you are using a default configuration without
any changes.
6. Click
Configure to complete the configuration. Repeat these steps for each channel of each module.
Launching the logger
Once all Smart Sensors have been connected and FlexSmart modules have been configured, access the Launch
window in HOBOware Pro and take the following steps:
1. Select the correct battery type (alkaline or lithium). If the battery type is not set correctly, the batteries
will not report their power accurately.
2. Review the list of channels. Make sure all of your sensors and modules are listed in the Launch window in
HOBOware Pro. The FlexSmart modules and Smart Sensors are listed in ascending order by serial number.
If more than 15 data channels are connected, the devices with the higher serial numbers will be ignored and
their data will not be recorded. The logger can only record 15 data channels at a time.
3. Log battery voltage? If you are using excitation power, you should also log the battery voltage. This
channel does not count towards the 15-channel limit.
4. Wrap? The Energy Logger Pro will stop logging when its memory is full, or you can enable wrapping.
With wrapping enabled, when the logger’s memory fills up, the newest measurements will overwrite the
oldest measurements.
5. Review other launch settings. Select logging and sampling intervals, and indicate whether you want to
begin logging now, wait for a timed delay, or a trigger start. Refer to the HOBOware Pro User’s Guide for
more information about these settings.
6. Click
Launch. Depending on the option you select, the logger may start automatically (either immediately
or at a specified time), or you may start it manually by pressing the
Push to Start button on the logger.
