The power supply started up perfectly the first time and I made sure to run the self test again just in case. After the knob is pulled off the front the dark cover needs to be removed. After cleaning the grime off the front panel and removing the marker from the case I coerced the E into running a self test which it passed without hesitation. Ships in weeks.

After doing a agilenr research I found that it was a known issue for the rotary encoders in these power supplies to fail. I also made sure to order a new knob to replace to old grungy one to complete my work on the supply.


By making it simple to connect, control instruments, and automate test sequences you can quickly move past the test development phase and access results faster than ever before with just a few clicks. This lead me to believe that the only issue with this power supply was that the rotary encoder was on its last legs. Would you like this item calibrated? Now to actually get it installed.
