Does anyone know how to calibrate this? Made in the UK.
First you sit down and eat your tea and crumpets.
then you complain about the price of petrol.
then you complain about the Americans. ( that is if you
are a Brit to start with). and after all of that.
if you still have interest in calibrating that meter.
You could then start looking at the manual.
personally, I don't thing the meter should nerd
calibrating. If so, and you're looking for very high
accuracy? I don't think you should be doing it.
Over here in good old USA. a Simpson 260 Analog
meter is considered a standard. Or at least, it once
was. ( I have one btw, in very good condition)
The point is that I have a class of students that must calibrate a piece of electronic equipment according to the manufacturer's instructions.
We have lots of these meters and since they are battery driven they are safe to dismantle.
I was hoping someone has done this.
Ok, well, I do remember (years ago no when I was a kid), a fresh carbon
cell was to output something like 1.56xxx , I can't remember exactly.
but that was the calibrator. Now days, I really don't think they do that
any more.:)
Sorry I couldn't of been any more help to you.
Mercury cells were good enough to use as a secondary standard when calibrated, and if not, new ones wer good to 5 digits (if i remember correctly - been ages).
