Default Error in idle current reading ?

I've been using the MicroPower E-logger for a years or so I guess.
I've had a good experience with it in general, and it's helped verify many air-plane and heli setups for me.

I have found a quirk though. I can get a current error depending on how I power up the logger. If I have the logger attached to my airplane BEFORE I plug the battery into the E-logger I seem to get a constant error current logged and also displayed on the Power Panel. If I unplug the airplane side but leave the E-logger attached the error current stays, the mAh reading advances too.

I've taken a photo to show the story.

Anyone know if it's a must to plug the power in to the logger and THEN plug the logger into the airplane ?

I've not been able to find anything about it in the manuals.

Hi Martin,

Sorry for the delay.

Our current software release has a calibration option that will allow you to eliminate the current offset problem you are experiencing.

I’d like to have you download and update to our latest software using the following link:


Once installed, please update your recorder and dashboard firmware by going to “Tools”… “Firmware Control” and updating to the latest version indicated.
You will find that in the "Tools" menu there is an option to "Rezero Current Sensors" - You'll want to connect your MicroPower to a 5.5V (or higher) battery pack through the "Source" input as well as all of the sensors you plan to use.

Please let me know if I can be of further assistance.

Best regards,
Don Gordon
