Thanks for the quick response. Yes the readings are fluctuating and the numbers posted are averages from the Fluke meter.
The -2.3ma EHA doe concerns me. Is it better to adjust the EHA to an average 0 ma or set the duty cycle close to 50% and let the EHA do its thing? Per your article, the -2.3ms would indicate a rich mixture. Is something wrong/off to have this combination?
As always, THANK YOU.
