the WB Jr. should be as good as you can get for accuracy of reading current.
As accurate as the shunt is anyway.

For the deltecs, that is +/- 0.25%, which is more accurate than ~95% of DMMs in the world.

Everything is still working.  The BMK and the WBJr are within about 3/4 of an amp from each other.

I would think they'd be closer together than that but probably close enough.

At what absolute current (approximately) were they off that relative amount  ?
