ABSTRACT:
The strength of an upright wooden structure is diagnosed by drawing a pair of spaced apart electrodes into the structure to a predetermined depth. The force of penetration and the moisture content of the structure at the depth of penetration are measured and the measurement data processed to provide an instantaneous readout indicative of the strength of the structure.
