10 Steps to Make the Most of Your Moisture Meter
If you own a Wagner moisture meter, you have one of the best tools on the market for monitoring moisture in wood on your jobsite. The IntelliSense™ technology designed into your meter yields quick and accurate readings of the moisture content in your materials. Here are the top 10 ways to make the most of your Wagner moisture meter.
1. Apply Pressure
Since your Wagner moisture meter is pinless, you will lay it on top of the wood to get a reading. Tip number one to get the most from your meter is to put some pressure on the meter when you lay it on the wood. About three pounds of pressure is ideal for a good reading.
2. Wipe off Standing Water
Before taking wood moisture readings, wipe off any standing or visible water and allow the surface to dry for 60 seconds or more. Standing or visible water always results in inaccurate readings, regardless of the meter type. For example, pin moisture meters with non-insulated pins give highly exaggerated readings when the wood surface is wet. Even Wagner pinless moisture meters will read a bit higher than normal, though typically less than 3 to 4%. Once the wood has been wiped and allowed to dry, Wagner meters with IntelliSense™ are able to give accurate readings in less time than other meters. Also, be aware that if water soaks into the wood, it will give a higher MC reading.
3. Is Your Moisture Meter the Right One?
Use the proper meter for the job. If you are working with an exotic wood species, your meter will need a meter with an extended SG range like the Wagner MMC220. If you require extended data collection capabilities for quality control, the Wagner MMI1100 offers data analysis functions as well. The right meter for the job will save you time and potential trouble down the road.
4. Consider the Subfloor
If you are measuring moisture content levels in installed flooring, the meter will probably pick up moisture in the subfloor. If the subfloor is made of wood products, this probably won’t skew the readings, but concrete will give a higher reading.
5. Beware of Metal
Never check the moisture content of a piece of wood lying on a metal table. Instead, hold it in the air to take a reading. The reason: Moisture meters are sensitive to anything conductive. Thus, taking a reading on a metal table or near any metal objects such as nails, staples, or metal studs renders the moisture meter ineffective, resulting in a false reading.
6. Don’t Be a Klutz!
Be careful with your meter. A Wagner moisture meter is calibrated at the factory, and will probably never need recalibrating. However, if you drop your meter, or it is accidentally submerged, it could be damaged. You should keep it on your belt loop in the provided carrying case for protection.
7. Keep Fresh Batteries on Hand
The batteries for your Wagner moisture meter are very long-lasting. However, it is always a good idea to keep spares with you. A quick switch of batteries on the jobsite will make a big difference in time-on-task.
8. Don’t Forget Your Manual
Keep the manuals handy. In addition to the operation manual, the Wagner moisture meter comes with another very useful manual that tells you the specific gravities for each wood you deal with. Be sure to check your manual to get the most from your meter. Both manuals fit nicely next to your meter in the protective carrying case.
9. Keep Your Meter Dry
Be sure there is no condensation on the sensing plate of your moisture meter. Just as the surface you are measuring should be free of visible moisture, the sensing plate should be clear as well.
10. Consider Your Wood Materials
Don’t forget that your Wagner moisture meter can be used to measure moisture content levels in plywood and OSB. Use the section in your Species Adjustment Table to set your meter to read these materials.
There you have it–10 ways to get the most from your Wagner moisture meter. These pointers will help you use your meter trouble-free for years to come.
