When all parameters/settings are set, press Start Device to program and begin recording data.
Device Menu: Stop Device
Select Stop Device from the Device Menu permits the software to communicate with the data logger
and stop it from taking additional measurements. The data logger will enter a low power state to
conserve battery life and when the memory is full. When full, the data recorder will stop recording
additional readings and place itself into a low power state to maximize battery life automatically, this
is simply a convenient way to extend the life of the battery. This mode is obvious to the user because
the device will immediately wake up when the host computer communicates with the logger. When
the device will not be used for a long period of time, stopping the device from collecting more data
will conserve power to extend battery life. Stopping the device has no effect on the data in memory,
the data is always retained.
Device Menu: Reset Device
Select Reset Device from the Device Menu to permit the software to communicate with the data
logger device, and stop it from taking further measurements. This will also erase all readings
currently stored in memory. Resetting the device will cause the data logger to enter a low power
state to conserve battery life.
Device Menu: Real Time Chart Recording
The Real Time Chart Recording command provides a graphical method for acquiring and viewing
data in real time. Choose the Real Time Chart Recording command to select the menu items and
toolbar to appear as shown below:
