[volt-nuts] Get 10K resistor calibrated in UK

[David C. Partridge]

I have recently acquired a Guildline 9330 10K resistor (thank you Phil).

One of my meters says 10,001.251 ohms at a room temperature of about 19.4C
which is a long way from 2.5ppm or even 12.5ppm (allowing for 5C at 2ppm
worst case).

Now the question has to be where in the UK (ideally in the Midlands) can I
get an accurate calibration of this standard resistor at a reasonable cost?

Thanks
Dave
