[volt-nuts] Fluke 893 vs 895.........or other?

Hello All, I am in the process of putting together AC/DC voltage standards in the home lab. I want to add the necessary equipment to check out the gear and need a differential voltmeter / null detector as called out in the service manuals for the Fluke 5200A and 332D that I have recently acqui

Re: [volt-nuts] volt-nuts Digest, Vol 63, Issue 5

So what I am hearing is that I should find either a Fluke 8506 or HP 3458A.h. I have always wanted that HP! : ) David ___ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mai

[volt-nuts] Sometimes you just gotta gloat............

Hello All, I have been on the lookout for a variety of different FLUKE equipment. And today, it all came together in a wonderful way. I went to my favorite local Equipment Surplus Center on the hunt for an HP 6260B DC PSU. Found one, 40 dollars. DONE!!! Or so I thought, until I decided to t

[volt-nuts] Fluke 720a self calibration repair

Hello All, I am trying to track down what I think is a small issue in the calibration of my new to me 720a. I am dreadfully paranoid of jacking something up in the process and need a little hand holding. I was going through the Self Calibration steps and every thing was going well up to the a

Re: [volt-nuts] Fluke 720a self calibration repair

Bill, After having spent the last couple of hours getting to know the switching, schematic, circuit, and layout I had a chance to lift the leg of R1006. Measured spot on as did R1005 and R1007. I was able to measure those resistors in the tank as well. Having done all of this I was thinking

[volt-nuts] Fluke 750a batteries.............

Hello All, I posted this over at the HP yahoo group as well, so pardon the redundancy if you belong to both or more. My new to me Fluke 750a reference divider arrived last evening and I have been having one heck of a time finding info on replacement battery options others have used on their 75

Re: [volt-nuts] Fluke 750a batteries.............

WOW Thank you for that. I must not know the best way to search the archives. I only know to go to google and type in my search and add volt-nuts febo.com Is there a better way to search the archives that I am not aware of? Cheers, David

Re: [volt-nuts] Fluke 720a self calibration repair

I like that Idea. Do you recall the part number of the resistors you found? Cheers, David ___ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.

Re: [volt-nuts] Fluke 720a self calibration repair

Thank you for all of the input on this folks. Does anyone have a copy of the datasheet for the original Ramo-Eltra P/N 3800P-502? The reason I ask is that the price of these parts is driven in part by the tempco and I found info that indicated 20ppm/C on one website, but that was not a DS, jus

[volt-nuts] Fluke 5205a Repair

Hello All, I know this is not specifically discussing precise voltage, but it is about producing it. We should consider starting a FLUKE calibration equipment repair forum. Anyhoo………I have been scratching my head over this 5205a issue for a couple weeks now. It presents with a OVERLOAD light

Re: [volt-nuts] Fluke 5205a Repair

Hello Chuck, You are absolutely correct, this is a one hand in your back pocket job, no doubt!!! This is VERY clean inside, in fact one might even say pristine. Which is just one of the many reasons I want to get it going properly. I re-seated all of the boards during the initial inspection

Re: [volt-nuts] Fluke 5205a Repair

Hello All, I am making a little more headway on this issue of the OVERLOAD & FAULT led’s being triggered and shutting down the system. In paragraph 3-34 on page 3-4 of the manual it states: Once U2-3 has been pulled low and a 3-9ms delay, the Operate FF J Input, U41-4 is supposed to go high.

Re: [volt-nuts] Fluke 720a self calibration repair

Thank you Bill. I think I found the exact same thing. I have to add them to the "need to order” list. I am very hopeful that I can get this whole analog ac/dc calibration nailed by the first of the year. Going at it from a mostly independent lab standards point, it is not an easy thing to ac

[volt-nuts] 540b Arrival...........

Hello All, My new to me 540b arrived last evening. I have never used one of these so I put it on the bench, opened it up and inspected it looking for leaks primarily. EVERYTHING is spotless. Fluke factory cal stickers everywhere. AND.after plugging her in over night, all of the batterie

Re: [volt-nuts] Fluke 5205a Repair

Hmm….. I am having one heck of a time tracking this one down folks. I am starting to entertain the idea that there is a possibility that somehow, me having this things wide open is causing my difficulties here. Besides having the “Lid Open and Disable switch,” I have that pulled u

Re: [volt-nuts] Fluke 5205a Repair

Hello All, Could someone be so kind as to measure TP1 and tell me what TP1 should read under normal circumstances. I am getting 7v at TP1 and need to know if this is correct or even close. I think it should be zero with zero input, but I am not certain. Cheers, David ___

[volt-nuts] Fluke 731b Rack Mounting

Hello All, I just picked up a 731b that I would like to mount in a rack with a back up UPS. I know that Fluke made the "Rack Mounting Kit M03-205-605" These were used to house up to four of these standards in the space of 3U, I think. The present day version of this is the Fluke 734a-7001. D

[volt-nuts] Solartron 7071 fair market value?

I have been trying to find some selling history for these units, but it seems to be lacking. Does anyone have an idea what these are going for in fully functional condition without probes, errors, or docs? Cheers, David ___ volt-nuts mailing list --

[volt-nuts] Solartron 7061 "CAL NOT DONE" error

Hello All, I recently picked up a 7061 and found it to have a “CAL NOT DONE” error on start-up. I understand this to mean that I need to calibrate the unit of course, but I was hoping some might have a little experience based guidance for the newbe owner of a solatron/schlumberger 7061. The l

Re: [volt-nuts] LTZ1000 project build

Heck, if you’re going to make one, you might as well make one GREAT. I would be interested in doing a 4910 version, so to speak. Four in one thermal box and the ability to use them independently or summed and averaged. Similar to the Fluke 730a, I think? Oh, and one of them must be removable

Re: [volt-nuts] Keithley 2001 vs HP 3457A multimeters / Any problems to watch out for on Keithley 2001?

Good Morning Dave, I just traded my 2001 for a 182 in equally nice condition. Each of them in solid working condition should fetch north of 1000USD. One of the hidden features of the 2001 is that it WILL display 8.5 digits on screen. It will not be as stable as running a Solartron 7071 in 8.

Re: [volt-nuts] 731B on eBay

They were from Harris Semiconductor which just shut down a fab plant not long ago. That is the assumption as all of the Fluke TE that seller has been moving is marked with a Harris sticker. Cheers, d > On Jul 5, 2016, at 6:49 PM, gilb...@nickgilbert.org wrote: > > Auctions for Fluke 731Bs for
