Fluke multimeter 8021 b users manual
That in mind, I washed the whole board in copious amounts of IPA including the switches , and after drying I sprayed all the switches with Deoxit F5 which is meant for switches. I may try Deoxit Gold instead should things continue to be funky. Closer inspection showed some corrosion around the lower right of the LCD, right where the three electrolytic capacitors are.
A search through my parts bins showed I had been smart, and ordered spare 22uF 16v electrolytic caps when I re-capped my Fluke a. Pulling the old caps from the B, they were green corroding. Putting the unit back together, it still read as off, but seemed 'better' and less noisy.
Looking through the manual, the calibration is actually pretty straight forward. The attached picture is the calibration procedure. I used my Rigol DP and DGZ to do the calibration, using my Keithley as the confirmation since neither Rigol units are exactly transfer sources.
The only notes is when doing the AC calibration using a Function Generator, make sure your source impedance is High-Z. Also the setting should be mVrms. Once I did all that, the unit calibrated easily, and the other ranges all checked out perfectly, including ohms, and current with reference to my DMMCheck.
Now I just need to replace the screen at some point using the same procedure I followed here. But right now, the screen is readable, so I don't care that much. Good luck if you get one of these units. I thought the issue was going to be the voltage reference, but instead it was just those caps.
Now I need to remember to order some more next time I have a Digikey or Mouser order. We just sent you an email. Please click the link in the email to confirm your subscription!
