Hybrid PV/Battery/Generator [RE-wrenches]

[Travis Creswell, Ozark Solar]

Hi Ray,

Thanks for tip and I just did try the Peak Min/Max feature.  I can't find a
reference in on the quick reference card for "Fast Peak" feature.  My meter
is an older 87.  I was wondering if you could look at peaks with an 87 and
never had a chance to figure it out yet.

Looks like it's peaking at 170.0 while recording at 1ms.

Travis
