[sdiy] Frequency Counter advice...

[David G. Dixon]

So, what do we use these doodads for?


> I've been using my Extech MM570 multimeter, clearly not as good as Paul's
> Fluke/Philips PM6666 :), but a good tool. Not cheap, but not so expensive
> that it's impossible to justify for personal use. About $300.00 new on the
> net for the non NIST certified version.

> FREQUENCY, AC LINE LEVEL:
> 		Range 5.0000Hz to 200.000kHz
> 		Accuracy 0.002% + 4d
> 		Sensitivity:
> 			500mV range 0.1V min
> 			5V range 1V min
> 			50V range 10V min
> 			500V range 100V min
> 			1000V range 900V min

> The meter itself is a decent volt/ohm/capacitance meter, too.
> 
> 0.03% basic DCV accuracy
> 50,000 count display with 500,000 counts for DCV and Hz
> True RMS combination AC+DC function
> Dual input Type K Thermometer
> High True RMS ACV bandwidth (up to 100kHz)
> 4 to 20mA, displayed as 0-100% for process current measurements
> 1000V input protection on all functions
> Highest resolution to 1µV, 0.01µA, 0.0001Hz, 0.01Ohm
