Purpose and Applicable Part/Model/Revision Numbers


This article pertains to the firmware in early HDN models..

Troubleshooting Steps 

Calibration of version r2.12 (original firmware) is performed the same way as version r13 and r14. The difference is that there is no way to calibrate by no more than a .1amp at a time. Additionally there is no zero offset.

When doing a field calibration the result will be when the panel is running load it will read properly. However when the panel is fully powered down the offset will read as the current displayed. For example if you had to raise channel A1 by .5A when there is no load it will read .5A.
