Unboxing

You can watch me unbox this thing over here: Unboxing ZKE Tech EBD-A20H Battery Tester Electronic Load | In The Lab With Jay Jay.

Documentation

To connect to this device via USB on 'verve' run EB Tester Software from the desktop. Use Device Manager and look for COM ports under Ports (COM & LPT) the EBD-A20H will be one of the CH340 options.

Notes

The power supply this thing arrived with was 12V @ 1A but I'm using a different 12V power source.
