Ok, maybe I can't see the wood for the fecking trees this morning but SWMBO dropped her hair dryer on my bench before going to work, telling me that it's making funny noises.
So ok, I get my meters out to do a continuity on the thing because it's one of these with the slip rings on the incoming mains supply so it can fully rotated without getting the power cord tangled.
So I connect it to my Brymen BM867 an unbelievable reading of 6.8M, so I try my MX52 and get the same, next I try HP3466A that reads 4.6M, HP3478A read 639K, Fluke 8842A reads 81.7K, Fluke 8840A agrees while the 7150 reads 3.8M and the other 7150 reads 3.8M
, so I get out my Avo Mk8 which shows about 6M, interesting.
Grab a 2M resistor and all meters agree on 2M?
In other news, postman dropped this off for me yesterday, must be about a lifetimes supply of .7mm 60/40 leaded solder, 1.1kG worth. I grabbed it quick while it was on Ebay because apparently while it has been banned from being used commercially where it is likely to used in volume as part of a production process, the EU have introduced a ban on sales to hobbyists as well now and I don't want to use that lead free shit if I can avoid it so better grab some if you can before we're forced to switch.
EDIT: WTF it would seem that meter manufacturers do not all stick to the rules when they make their meters as the hairdryer has some form of rectification in it for the fan motor and so it would seem to be logical to assume would it not that the red terminal on a meter would denote the positive regardless of if you were reading DC volts or taking a resistance measurement? Different manufacturers think otherwise, on the meters that were giving me readings in Mohms, swapping the jacks over on the meter produced more consistent readings. As Dave would say "A trap for the young players"
