I've turned mine on during the Santa Ana's and I've had it pop up at 16% and then over a few seconds it goes to 14, 12, 10 and then it goes blank with dashes after that. I think they may be referring to their spec range as the range for their stated accuracy (3%). Just a guess... As for repeatability, I've had good results with that. I once tuned a piano in a clear plastic tent. It was 70F outside and 90F on the inside. With the freshly watered lawn below and the condensation dripping from above, the humidity was quite high. I think around 63% or so. I took the device out of the tent during my water breaks, and when I went back in, it rose to the same numbers, plus or minus 1%. Did that 4-5 times over the course of the tuning. Here's a photo of that piano. My jacket is draped over the end to keep the strings out of the direct sunlight.

I educate them as to how humidity has an effect on their piano's tuning. Then I show them where the current RH and temp is and then it is written on their invoice. When I come back in 6 months we repeat the process. They see how it works and they're happy. And then they tune their piano twice a year because they notice the change in the seasons. >> >> It's especially fun when I turn it on during the Santa Ana winds we have out here and they see 10% or less... :-) >> >> Regards, >> >> Rob McCall >> >> McCall Piano Service, LLC >> www.mccallpiano.com >> Murrieta, CA >> 951-698-1875 >> >> On Sep 09, 2012, at 14:17 , Ron Nossaman wrote: >> >> > On 9/9/2012 2:28 PM, Rob McCall wrote: >> > >> >> It's well within my budget, it's compact and easy to carry, easy to >> >> read, and I find it accurate enough for the work I do.

I find that absolute accuracy is not of much use to me, but I do want good repeatability on readings, even if they're both 3% off absolute. What's important to me is the difference between RH% readings from visit to visit, to a fair degree of accuracy.
