Manual here http://www.mcmelectronics.com/content/ProductData/Manuals/94-410.pdfTips http://www.mmccs.com/mmarc/n0ss/hakko_808_notes.pdf The manual says the heater should measure 40-50 ohms on the 120v model and 210-270 on 240v models. If that looks good I'd check the temp control pot.

I plugged mine in today and it stayed cold. The pump works fine, so I know it has power. The heater seems to be in good shape so I suspect the circuit board that supplies current to the heater. I've tried measuring the voltage on the red wires that supply the heater, both AC and DC and there doesn't seem to be much there. Does anyone here know (or could check) what the voltage on the red wires should be? Or maybe the heater is bad and the board doesn't provide any current if it is open (or short). A value for the resistance across the heater would be good to know too. Has anybody here had a similar experience and knows a quick easy fix?

hello all! i just acquired a Fluke 9020A troubleshooter with option 002 ieee488 interface at a good price, and i have an operators manual and service manual on the way. does anyone know if i need to change roms if i swap the gpib interface for an rs232 interface ?

I'll look for it Tuesday and report back here... I can take a few pictures of it. (I might even have a Track Pack boardset and could just read the PROM in here. I don't remember what's our machine in storage. I'll look. If nothing else, if our PCB is the original one just reading and duplicating that would serve as a proof of concept.) OE&CE can just be disconnected. Looking at the schematics all the outputs are going to be push/pull (no tristate), so nothing 'special' required to brute-force the dump.

Re: [Techtoolslist] Fluke 9020a - need replacement "low pulse" key switch
by Brent Walker 17 Mar '15

17 Mar '15

Andy, I had a similar issue on a 9010a I picked up several months ago - the key would stick down and not want to come back up, or wouldn’t lock down at all. I unsoldered the switch from the keyboard, at which point it’s not too hard work on. I suspect the little wire piece that flips back and forth got bent, and you’ll need to gently get it bent back into position - not necessarily an easy task. You may need some light lubrication in it as well (I used a bit of silicon spray). If you’re handy with that type of thing, it can definitely be done; I spent about 30 to 45 minutes tweaking mine until I was happy with it. It clicks back and forth consistently about 90% of the time, which was good enough for me, and much better than it was. Either way, these switches aren’t too common, so fixing it is your best shot I suspect - good luck!

I recently bought a Fluke 9020a w ieee-488 interface and the "low pulse" key switch behaves as a momentary sw only whereas the "high pulse" switch is a toggle - PTMK-PTBRK. on reading a post by Martin from 2006 i realised my LOW pulse" sw probably needs replacement. anyone know of a source for the switch mechanism ? anyone repaired or lubricated the switch successfully ? cheers, andy _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

9020A via IEEE-488?
by Nigel Williams 17 Mar '15

17 Mar '15

I recently acquired a 9020A with a IEEE-488 interface and wondering if anyone has documents for using this configuration. I found the 9010A vs 9020A differences document from Fluke, but I'm not sure what software was used to control the 9020A via the 488 bus. I would be interested in the service manual and operating manual for the 9020A if anyone has spares too please. thanks. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Changing mains voltage for power supply PSU on the Fluke 9020A
by Nigel Williams 17 Mar '15

17 Mar '15

In the interest of saving someone else a little time, if you need to change the line-voltage on the Fluke 9020A micro-tester then refer to the following pictures: http://imgur.com/a/Im6bF#0 In the final picture are two slide switches in the lower middle, on the PCB there is an indication of the voltage options and you can adjust the switches, for 240V I swapped them from how they appear in the picture (which was how they were set for 110V). Safety-first, don't try this at home without supervision etc unless you know what you're doing. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
