Relative Humidity almost always 99%
Maybe someone can help me. My weather station (National Geographic 265NC) almost always displays 99% relative humidity. I know this can't be the case as other stations around me are reporting lower RH.
I've only had it set up a few days in a temp. location that was only a foot off the ground, I thought that might have cause humid conditions because of the grass, so I raised it to about 6 feet, but no change in RH.
Thought?

Re: Relative Humidity almost always 99%
What figures are the stations around you reporting? If you're certain that it's reading far too high, then it's most likely a faulty sensor, I think.

Re: Relative Humidity almost always 99%
Looking at locations near me on wundermap, the 3 closest to me are at 73, 73 and 48 %

Re: Relative Humidity almost always 99%
My humidity sensor was showing 99% most of the time until I took the unit out of the near useless screen provided and put it in a much bigger Stevenson screen. Now, although 99% is common, it does go down to 60% ish at times of dry weather and a breeze.

Re: Relative Humidity almost always 99%
Hi
I was getting 99% pretty much all of the time but I had to replace the transmitter for other reasons and the new one in exactly the same location/screen etc behaved more or less normally - so I would say - faulty unit.
Regards
Alan

Re: Relative Humidity almost always 99%
I spoke with a Thermor rep. at the Home Hardware Show and they told me it was a faulty monitor unit. It's not receiving the radio signal correctly from the outside unit. It's a known issue with the 265. I'm to contact customer service tomorrow and they will send me a new unit by mail.

Re: Relative Humidity almost always 99%
Well, I guess they ought to know, but that doesn't sound right to me. If you're getting all of the other outside measurements correctly - which I assume you are, or you would have mentioned it - then I don't see how it can be a problem with radio reception. But I don't know anything about the radio transmission protocol on these things, so perhaps all of the data isn't sent together. But I guess you'll soon know one way or the other!NarrowAcres wrote:I spoke with a Thermor rep. at the Home Hardware Show and they told me it was a faulty monitor unit.

Re: Relative Humidity almost always 99%
Yeah, I thought the same thing, it must be one of the sensors outside, but as soon as I said my outside RH was 99%, she was saying, "oh, it's the touch screen monitor."steve wrote:Well, I guess they ought to know, but that doesn't sound right to me.

Calling them now...

Re: Relative Humidity almost always 99%
Wow, I'm impressed. I called and the lady I spoke with said, "Oh, I was told you were going to be calling us. Just give us your information and we'll mail you out a new unit right away."
Fast, friendly service. Kudos to Thermor. I should get the new monitor early next week and hopefully my RH problem is solved.

Re: Relative Humidity almost always 99%
If your problem is the same as mine replacing the consule will not help you.
Try unplugging the anemometer for a little while and see if the RH goes to something
more reasonable.
If that works for you then I wish I could offer you more help but I still have the problem
myself.

Re: Relative Humidity almost always 99%
I think my humidity sensor has gone wrong this morning. A sudden drop. I'll have to investigate. Fortunately I have a spare tx/temp/humidity unit. Humidity plot attached...

Re: Relative Humidity almost always 99%
Strangely, it seems to have returned to normal.
Anyone have any idea of what could have caused that strange drop in readings?You do not have the required permissions to view the files attached to this post.

Re: Relative Humidity almost always 99%
I have seen something similar when changing the batteries - almost like it has an initial value and then integrates many readings to build a "correct" answer over time. No power interruptions to the sensor unit that you are aware of?

Re: Relative Humidity almost always 99%
I haven't touched the tx unit for some time other than to disconnect and reconnect the rain gauge. But that wasn't during the trouble period or even that day. I think I'm going to have to bring the unit indoors again and give it a good looking at. I have the temperature spikes back as well - for a week or so now.
