“Tools, Rezero current sensors” and follow the instructions on that page. Note that this only needs to be done once, but it’s not a bad idea to do it
once a year or so, to account for any slight current sensor drift over time.
Special Instructions for the High Voltage Sensor
If you ordered the High Voltage option with your Recorder, complete the following step:
•
Connect the Recorder and click “Advanced, Custom Hardware Options” and click ON the option “My Recorder has the High Voltage
option.” Then, click “OK”.
Special Instructions for 140 Amp and 300 Amp Sensors
If you are using the
300 Amp Sensor
, complete the following step:
•
Connect the Recorder and click “Advanced, Custom Hardware Options” and click ON the option “I am using the 300 Amp Current
Sensor.” Then, click “OK”.
If you are using the
140 Amp Sensor
, complete the following step:
•
Connect the Recorder and click “Advanced, Custom Hardware Options” and click ON the option “I am using the 140 Amp Current
Sensor.” Then, click “OK”.
Recorder Logging Setup
If you desire to log current or voltage in the Recorder, connect the Recorder to your PC as described in the Recorder manual, and under Tools-
>Choose What to Log, choose Electric Motor Voltage and Electric Motor Current in the Optional Parameters section. Choose other parameters you
want to log as described in the Recorder manual.
To display the new parameters, under Tools->Choose What to Display, choose numeric and/or instrument display of Motor Voltage, Motor Current,
Motor Wattage, and/or cumulative amp-hours.
Seagull Dashboard Setup
If you are using the Seagull Wireless system, choose “Tools, Choose Parameters to Display on the Seagull Dashboard” and select the desired
Dashboard parameters to display, per the Seagull manual.
Playing Back Data after the Run
After your race, download data to your PC as described in the Recorder Manual. If you have selected to log and display motor voltage, current,
and/or RPM, these instruments and/or numerical readouts should appear in the application.
Troubleshooting
Below is a list of problems that may be encountered, and steps to remedy them. If your particular issue is not addressed by the below, see the
Support page on
or email
. Include a full description of your problem, your machine
configuration, brands/models of receivers, transmitters and servos, application and Recorder firmware version if possible (from Help->About in the
app) and any other relevant details.
Issue:
I do not see motor voltage and/or current values changing after using the
Expander.
Solution:
•
Make sure that you have selected logging of voltage and/or current in
the “Choose What to Log” dialog box under the Tools menu.
•
If voltage measurement is not working, but current is working, see
the “
ESC’s with isolation between BEC/Throttle ground and Main
Battery Ground”
section above.
•
If Current is not working correctly, please verify that the Ring sensor
is correctly installed on the Electric Expander harness. Please see
the figure below.
•
Ensure that you have selected motor voltage and/or current in the
“Choose What to Display” dialog box under the Tools menu.
•
Double check your connections to ensure that the Recorder is
connected correctly to the Electric Expander, and the battery.
•
Ensure that you are operating within the ranges listed in the Specifications section below.
Issue:
My Electric Expander seems to be out of calibration. The readings I receive for current and/or voltage are somewhat incorrect or differ
slightly from my favorite meter.
Solutions:
•
If you have a “High Voltage” recorder, or a “High Current” (140 or 300 amp) Electric Expander, ensure you have made the “Custom
Hardware Options” settings as described above.
•
If the current sensor appears to be reading incorrectly, make sure you’ve performed the steps in the “
Zeroing the Current Sensor for First
Time Use”
section above.
•
ADVANCED: If current and/or voltage seem to be reading slightly incorrectly, or you wish to calibrate the readings to a particular meter
you use, click “Tools, Calibrate Pack Voltage and Amperage Readings” in the windows application, and follow the instructions.
