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

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

Re: [volt-nuts] Prema 6048 Cal switch confusion

I just had an email from Prema about this - - long story short: In this particular application, the DS1220AD isn't a good replacement for the DS1220Y as the timings differ enough to cause a problem. Prema suggested to use a ST M48Z02-150PC1, so I've ordered one from CPC. Dave -Original
