AbstractThis report assesses the dynamic uncertainty in capacitance wave probe measurements when calibrated and applied statically. It also proves which wave probe circuitry typically produces the least error over the specified frequency and amplitude ranges. The experiment was conducted using the Oceanic Corp. 3-Axis Linear Table Arrangement, which required custom Visual Basic motor controller software and several custom Igor procedures for run-generation and final data analysis. Based on the final data analysis, the investigation shows that both the Branckner and modified wave probe circuitries reported similar dynamic errors (about ± 3 mm) with offsets close to zero, while the unmodified circuitry consistently showed greater errors with an offset of 3 mm.
