No. The point is, you can't just stick the metre in and expect anything meaningful.
What are you checking for? What locations are you checking? What materials? What other factors may influence the readings? Are you trying to determine rising, penetrating or condensation issues?
All the meter is telling you is that a particular point in a section of timber has a specific moisture content on or near the surface. The interpretation is what does this mean in context - i.e. is it a probelm or normal?
The meter is callibrated for timber, and so use on other materials will not give accurate comparisons. Use on other materials can only be used as relative guide to other readings on that same material
