Hello Graham, it's a digital. Pretty average, and I'm transferring exactly what comes up on the screen for the given ranges. That's not to say I am using it correctly though! Nor can I vouch for the last time it had a new battery - a while back.

If I am using the 20k ohm range and it shows 2.53 in the display, I would interpret that as 2.53 x 1000 = 2,530 ohms. Correct me if I'm wrong. Is 2.53k as it seems to be, too far away from 2.2k as per spec?

R27 does seem to be way out at 80 ohms.

Sorry "no reading" - I should of course be saying 'open circuit' - the numbers didn't change from 1, the resistance of air.
