Servo Current:
Choose this option if you want to record servo current with the optional Servo Current MicroSensor.
All GPS Parameters:
Choose this option if you want to record GPS Parameters with the optional GPS Expander.
Spektrum™ AR9000™ Flight Log Interface:
Choose this option if you want to record AR9000™ or JR 921™ receiver
performance data, with the optional Spektrum™ cable.
Setting the “Stop on Full” Feature
After you complete the New Model Wizard for the first time, you will be prompted to choose whether you want the eLogger to write
over its data when its buffer becomes full, or to stop when the eLogger is full. NOTE: You can change this setting later from the
Hardware menu of the Windows application. If you select “Stop on Full” the eLogger’s LED will flash two flashes in a row when
the buffer is full.
Setting the “Set Capture Rate” Feature
The eLogger can be adjusted to capture data in during the recording session at five different rates. The faster the capture rate, the
more data is obtained, but at the expense of record time. The default rate, ten samples/second, gives the best resolution, but the
record times will be lower than with lower sample rates. You may find that you can get plenty of record time even with the highest
capture rate setting, however.
Note: You can change this setting later from the Hardware menu of the Windows application.
A note on record time: The eLogger uses advanced data compression to get the most data recorded as possible. When your model is
sitting idle before or after the session with the battery turned on, the eLogger is still capturing data, but since not much is changing
very little data is recorded. But when the model is active more data is being recorded.
Setting the “Choose What to Display on the PC Screen” Feature
The eLogger Application can display several model parameters in both numeric and instrument format. Select the parameters you
wish the Application to display with this dialog box. Note that some of the parameters require optional accessories, available from
Eagle Tree Systems.
Note: Select the “Metric” checkbox on this dialog if you want metric operation.
Also, you can change these settings later from the Software menu of the Windows application.
Configuring and Calibrating the Throttle Function of the Expander with the Windows
Application
Calibrating Throttle Movement
It is not absolutely necessary to calibrate the throttle function. The advantages of calibration are that the throttle gauge and graphs
will range from zero (closed throttle) to approximately 210 (maximum throttle), as you move your throttle between its extremes. If
you do not calibrate, the throttle gauge and graphs will still show throttle movement, but the graph could be inverted if you have the
throttle servo reversed, and will not go from zero to 210.
To calibrate the throttle with your model, first connect the throttle Y cable as described above, and connect the eLogger to your PC
via the USB cable. Then, click “Calibration, Calibrate Throttle.” The Calibrate Throttle Wizard will then explain the calibration
procedure.
Using the eLogger
Once the eLogger and application is installed, it’s almost time to operate!
Please read the important information below
on
eLogger operation before using it at the field in your model.
