Default Re: Meter Suggestions for Basic Alignment/Calibration

Ian,
if you have an Fluke 89-why do you need an 87?
OK, both are practically same accurate and counts 50000/5000 but a 89 has lot more functions, is a usabler datalogger...
If you search for 89 specifications: you can read values of cca 0,15-0,25% or so.
In my opinion, if it would be only 0,5%=> far enough precise for a check/calibration of analog movements with readability of maximum 1-2%.
Otherweise, as I wrote before; more simple and 5-10 times preciser would be a movement calibration wit DC-voltage drop measuring over good knowed precisions resistor as DC current measuring...
rgds, Karl
