Hi all,
I bought something today that I shouldn't have so this needs to go temporarily to replace the money spent!
Clean Hewlett Packard E3631a for sale. Pics show the three outputs into my in cal 34465a meter.
According to the tag the supply was last calibrated in April 2016. All outputs work well and I've been happily using on my bench.
The 6 Volt output seems to drift downward very slightly when the unit is powered up, a few mV over the time and then it settles, not sure if this is normal. The 6V out also reads off by a few mV as you can see in the pic.
Also on the 6V output the current reading is off by a consistent 60mV (reading high). The current limit is working correctly. On the +/- 25V outs the current reading is correct to within a mV and the current limits functions correctly across the range. If I have time tomorrow evening I will adjust the current reading on the 6V channel.
Did a user cal and everything is measuring very close to perfect now.
Chassis of the unit is very clean, there is one small dent in the front panel that I tried to photograph. I tried to create the worst possible conditions for the VFD - overhead lights on in lab, my Luxo magnifier (2 x neon) shining straight at front panel and compare to my 34465a which has the brightest display of anything I own.
If you have any questions just let me know.
Asking $450, down to $399, last price drop to $375 need this to move. Payment via paypal plus shipping at actual cost (USPS or Fedex my preference). I will cover the paypal fees, shipping on you. The supply will ship from Los Angeles, CA.
I'd prefer a U.S. sale if possible.
Thanks!
