Question 1

When using a non-penetrating moisture meter, what does the reading actually measure?

Accepted Answer

Capacitance changes caused by moisture presence

Answer

Non-penetrating meters use capacitance (radio frequency) technology to detect moisture without damaging the material surface.

Question 2

A restorer documents a moisture reading of 'WET' on a relative scale meter in drywall. What is the primary limitation of this notation?

Accepted Answer

It provides no repeatable numeric benchmark for drying progress

Answer

Relative scale readings lack numeric precision, making it impossible to objectively track drying progress across multiple inspections.

Question 3

Which condition is MOST likely to cause a false-high moisture reading with a pin-type meter?

Accepted Answer

Salt deposits or conductive materials in the substrate

Answer

Salt and other conductive contaminants increase electrical conductivity, causing pin meters to report falsely elevated moisture content.

Question 4

According to IICRC S500, psychrometric data collected during drying should be recorded at minimum how often?

Accepted Answer

At every inspection visit

Answer

IICRC S500 requires psychrometric readings at every inspection visit to document drying progress and validate equipment performance.

Question 5

A floor moisture map shows elevated readings in a checkerboard pattern with no obvious water source. What is the MOST likely explanation?

Accepted Answer

Vapor barrier failure under the slab

Answer

A checkerboard pattern of elevated moisture in flooring without a discrete source often indicates a compromised vapor barrier allowing ground moisture to migrate unevenly.
