[R-390] Warning - off topic but technical

[Leigh Sedgwick]

I have an old Fluke 77 digital voltmeter.  The specifications in the manual 
do not specify a frequency range for AC measurement accuracy.  Does someone 
on the list know the frequency limitation of this meter.  I'm assuming it is 
around 500 hz or is it even lower than that?

Sorry for the off topic post but I know there are some very knowledgeable 
folks on here.

Thanks
