content: GuyzzI just bought a EDC DC millivolt calibrator E100C , is $215 a fair price ?I think it's the same as the Kron-Hite E100RC.The KronHite-Manual says it stops after section3 (and $$ for the full manual) , the other has to section 4.So i was wondering anyone has the full manual for either the KH E100Ror even better the EDC E100C/Bingo

content: Following a tip i got on the volt-nuts listI emailed Kron-Hite service , asking if it would be possible to get a copy of the service manual.And i just got a very plesant response from their Service Department Manager ,with the complete E100C service manual attached , and a best of luck with the restoration project.Rumours are that the electrolyte caps needs changing , and the dials needs a good cleaning and lubrication.I just love when the companies are willing to support their old products and us hobbyists.This imho puts Krohn-Hite "on par" with HP.Thumbs up Krohn-Hite , and thank you for the excellent service./Bingo

content: I just got my unit.Here are some initial pics attached as a zip archive.I was adviced to change all the Electrolytes , and clean the contacts with caig DeoxITCleanerhttp://www.micro-tools.de/Kontaktreiniger-oxid/CAIG-DeoxIT-D5-Spray-142-g.htmlLubricanthttp://www.playstereo.com/product_info.php?products_id=275&cPath=13&language=enThe contacts seems to need a good cleaning , and i was thinking of a toothbrush and some IPA for initial cleaning.Then use the above caig cleaner , and finish by lub'ing with the caig lube.Any hints to clean such switches are very welcome./Bingo

content: Speaking of E100 calibrators, does anyone have or know where to find the 100:1 precision voltage divider device within one of these? I have a E100 that is in need.

content: Hey Doc,I have already been down that path. Apparently, they don't stock the part anymore.I figure I am not the only one who has the Pre 100C model (think it is a E100A not sure). I have considered contacting Precision Resistor Company (PRC) to see if they can build one, but a 1 off copy might not be cost effective.Thank you,JLM

content: Quote from: jlmoon on September 02, 2015, 09:57:52 pmSorry, I have not recieved mine yet as it should arrive within a week. Bought from ebay for 150 dollars. Where in the schematic is it? When you contact PRC let me know what the cost is and Will share cost with you to one or two for myself.

content: Quote from: Docholiday on September 02, 2015, 10:22:56 pmHello Doc,Working with the service manual I have which is the E100-RC version (might not be exact, guess I need one of the early copies as well) It is listed as Part Number "PRE054". According to Krohn Hite, it is a preselected part (PRE-fix) so I am not sure what the various (tol, tempco, etc) parameters should be. The schematic I have lists the part as a A-3600 and the location designation is R48.I will continue to dig around and get more data as time permits.Thank you,Jon

content: Quote from: jlmoon on September 05, 2015, 03:31:09 amI have not received my E100 yet until this Friday but is part the "Divider 20 ohm" ? The E100 shipped to me is supposed to be 100 per cent operational in spec as well. Perhaps taking some measurements would help you? And I too contact Kron requesting the same info/solution might also help too.Nicholas

content: Quote from: Docholiday on September 02, 2015, 03:33:38 amSeems like this is (and will continue to be) a regular request--if anyone has a complete (i.e., user+service portions) manual for EDC/K-H E100C and/or E100RC voltage references, I'd be glad to host those manuals on one of my web sites for all to download.As it happens, I also am in need of one of these manuals.JP
