Also now I wonder what do those specs mean?
I explain about multimeter specifications here: https://lygte-info.dk/info/DMMTolerances%20UK.html
Usual they are only valid between 18°C to 28°C, for each degree outside you must add some more tolerance.
Thank you, that's a nice explanations page you developed!
So, then for the Brymen 869s in the video, specs for the 500.00mV range is:
DC Voltage, 869s, 500.00mV, 5.0000V, 0.02% + 2d
And since this spec is for 50,000 count range, I think I need to drop the last digit from the 500,000 count readings shown in the video (is this correct?).
Since Joe is measuring 1.00mV (assumed), according to the spec, readings should be:
1.00mV x 0.02% = 0.0002mV, and add 2 counts of 0.01mV and you get 0.0202mV, or for the meter 0.02mV.
So to meet specs, the meter needs to show something between 1.020mv and 0.980mV... is this right?
