For sale is my Fluke 731B DC reference standard, serial # 820012. The unit is in excellent condition and works as it should, it is very clean inside and out. The red banana post has a small crack from age.
It provides 10 volts, 1.018, 1.019 and a microvolt output. The microvolt vernier works great. The batteries have been replaced with Eneloop AAA's. PPM error per degree C has been verified to perform better then Fluke specifications. The 10 volt output has been adjusted to match my 732A. No batteries have ever leaked inside the unit.
SOLD, payment via paypal. I can ship anywhere via UPS and get pretty good rates.
It will be shipped powered off unless you're really close, thankfully the 731B's don't seem to mind much.
Local sales in the greater Vancouver, BC area are also very welcomed.
Any questions feel free to ask!
