Accurate voltage measurements

I am now the proud owner of a shiny new true RMS multi meter I've seen revues of it on YouTube and it gets very good reviews on all aspects of its accuracy and construction and of course safety not sure if I'm aloud to say  which one it is maybe someone will tell me if its ok.  Anyhow it reads the same as 2 of my other meters which are also true RMS  although I didn't know they where. Any how I've found out that the 2 LED meters I bought  that I posted about some time ago are both telling lies although one of them is occasionally telling the truth. It's interesting that the voltage is never still  but is usually around 240 and also if I look at around 23:30 it drops off by 3 to 4 volts which must be when local economy 7 kicks in

  • Hi I don't know the specs on the lying meters they came with no instructions or spec sheet just the 2 meters in there own little plastic bags I suppose that should of been a warning to me but I was caught up in the moment. The meter I have now is an Astro AI 6000AR  Says its 6000 counts not sure what that means. It Messerschmitt down to one decimal place and when it reads say 240.7 another meter flickers between 240 and 241 another one reads a solid 241  so I'm confident that what I'm reading is right certainly right enough for me. I can't afford to get it calibrated that's way to expensive I struggled raising the £25 the meter cost!
