FS: Upgraded Fluke 8842A with LED display, Continuity Buzzer, GPIB, AC

[bikeNomad]

I'm very fond of the Fluke 8840A and 8842A meters and have designed a continuity buzzer circuit that's in two forms (a board that plugs on to the back of the display board and a replacement for the entire display/keyboard PCBA that takes either AHOL's LED display or the original VFD).

I'm selling an 8842A that's been upgraded by the addition of one of the new display/keyboard/continuity buzzer boards and an AHOL LED display replacement.

All the electrolytic capacitors have been replaced, and every range has been tested against a known-good meter on both front and rear terminals. I have also tested the GPIB interface.

This particular unit was produced in early 1997, passes the internal self test, and has:

• GPIB option 05
• AC option 09
• New LED display
• New keyboard PCBA
• New continuity buzzer
• Handle
