What to do if your current sensor is reading incorrectly

If your eLogger or Data Recorder Electric Expander current sensor is inaccurate, what may be happening is that your setup has a steady non-zero draw after powerup. We're seeing more and more of this with larger ESC's/Motors.

To fix this, simply install th Eagle Tree Windows application version 5.66 or later, and click "Tools, Rezero Current Sensors."

This works with our eLogger, our Electric Expanders, and our new Servo Current Sensor. It is especially useful with the Servo Current Sensor, since servos draw a small amount of current even when they are not moving.

Just make sure that there is no current draw through the sensor when doing the Rezero. Also make sure that you have a battery connected to your eLogger during this step.

NOTE: All eLogger V3 units are shipped with the zero current pre-calibrated, so this step should not be necessary.
