A measurement system, its assembly and use are disclose. The system may include an instrument for making sensor measurements. The instrument has a substantially cylindrical housing. The shape and size allow the instrument to easily fit in an average hand enabling handheld operation. The housing houses a board stack of electronic boards. These electronics drive an electrical signal in at least one drive channel and measure responses from at least two sensing channels. These responses are provided to a processor for analysis. The instrument has a sensor connector that enables simultaneous electrical and mechanical attachment of an end effector.

Measurement system and method of use

A system and method are disclosed for enhancing pit detection and sizing in a test object. Response signatures are created and stored in a signature library to characterize various sensor responses (liftoff, orientation) and pit properties (e.g., depth, width), possibly with or without additional considerations (e.g., edges, cracks). A sensor is placed on and scanned across a surface of interest on the test object. During scanning the sensor is measured repeatedly at regular intervals. An encoder may be used to record the sensor position for each measurement. The measurement results are then correlated with one or more signatures in the signature library. A threshold is used to determine if the correlation is indicative of the detection of a pit. If so additional processing may be performed to estimate pit properties.
