Re: HP6209B component location layout
You will also likely need to replace R12,13 parallel combination ~2K ohm 3W. R13 is a 1/2W trim resistor, this is between a 6.2V source and terminal A7 on the back. the equation is

Re: HP6209B component location layout
Thank you for the information, that saved me some ghost hunting for drifted resistors in the meter circuit. Both the voltage and current adjustment pots are Bourns series 3540 which are rated at

Re: LCR Meter E4980A Power On Test Fail
Sounds like that might be a firmware problem if it works when forced into an alternate mode. If there is a firmware download it might be worth checking. Regards Nigel

Re: HP6209B component location layout
Besides the effects on the metering, you may want to check the power rating of the volts pot. The original 100 kR value would dissipate about a watt at full output, now about 2 W with 50 kR. If these

It would be better than nothing. I actually got rid of my fiche reader/printer about 8 years ago after not having used it in over 10 years. Never say never, LOL. Richard

I'd try 2N4119A or PN4119A. I might have some... Mouser are mighty proud of them. [email protected]> wrote:

ArtekManuals have at least one version of the 3460A manual, but not the H04 option. I also have some info on the chopper oscillator modification, used in the later 3459/60 voltmeters, which is

Re: Looking for the manual for the HP H04-3460B or 3460B opt H04
The H04 manual for the 3460 *A* is just the normal manual with some change sheets for the H04 modifications, if there is a 3460 *B* H04 version you should be able to use the 3460 *B* manual at the web

Re: HP6209B component location layout
The current through the 100k pot is normally 3.2mA.to change that to 50k would require doubling the current to 6.4mA. This additional current will show up as an offset on the current meter. The 6207
