Hi Robert,

Thanks for that the manual takes you through all the error budget calculations and usage as a Hamon divider etc. It seems there are 1 ohm resistors matched to 0.05% in the parallel shorting bar, still trying to work out how the sries parallel shorting bar is wired. Does anyone know haw the series/parallel shorting bar is wired?

I saw a series parallel bar on ebay, but it is for sale for quite a bit more than I paid for the SR1010!

Initially sent to Robert rather than the volt-nuts group.

thanks,

MK

Hi,
Nice unit.
IET labs still make these. The product page is http://www.ietlabs.com/esi-sr1010-resistance-transfer-standard.html and has links to download the manual, application notes and data sheet. As well as shorting bars these units use compensating resistor units. IIRC the manual (what a 68 page manual for 12 resistors in a box? How hard could it be :-) has references if you need more info.

Hi,

I have just bought an SR1010-10k for a good price and I was wondering if anyone knew what the interconnect is for the parallel and series parrallel shunt bars?

Regards
