## Questions & Answers

**Q: accuracy**
A: I found the stated range of error to be ambiguous. It was stated as being within 3% of the reading. But the units of measure of the reading are themselves in percent.So I wrote the following to the manufacturer, asking if I had a reading of, say, 10% did that mean the range of error was 9.97 - 10.03% or 7 - 13%.This was their reply:The accuracy is ±(3% + 3 digits) as stated in the manual.  To use your example, if the meter reads 10% then it is really between 7%-13%.  The website will be updated accordingly.  Thank you for bringing this to our attention and if there is anything else you have questions about, please feel free to contact us.

**Q: Can I use this product to rule out a plumbing leak under my concrete bathroom floor.  The outer bathroom wall is concrete & paint is bubbling.**
A: It won't show thru the cement unless it is wet. Also is the wall an exterior wall & you could be getting moisture there. With the paint bubbling you do have a water problem from some where inside or out, but you could check with the tool on the inside in the wall real low next to the cement. It worked real well for my particular problem without tearing up the carpet to find my problem. Hope this helps.

**Q: I have a wooden floor that is swelling little bit. I know I had a small water leak. Can this tool help me to check if there is moisture underneath?**
A: ABSOLUTELY!  This is just what you need, it tells you the exact moisture where the contacts touch the wood.  There is a small button on the face right under the word GENERAL that allows you to pick wood or concrete.  I use it on our Maple flooring in the summer to see where we are with water content.

**Q: Will it measure moisture in drywall?**
A: Yes.   It has two features (1) Wood which I use on dry wall, wood, plastered walls, carpeting.. (2) Building material which I use on concrete floors, concrete blocks...  I have found it works well on concrete and I can trace moisture in our basement floors which has helped to target where work needs to be done in outside grading.  By the way I am a 78 year old woman and have had "fun" using this meter.  Money well spent.
