Measurement accuracy of a remote visual inspection (RVI) system is tested using a test object including a test feature having a known geometric characteristic. Using a controller, attachment of a detachable measurement optical tip to an RVI probe is detected. A user is then prompted to perform testing of the measurement accuracy. When the user indicates the test feature is visible, the system captures one or more images of the test feature, determines coordinates of the test feature from the images, and measures a geometric characteristic of the test feature using the coordinates. An accuracy result is determined using the measured geometric characteristic and the known geometric characteristic, and an indication is provided, e.g., to the user, of the result of the comparison. An RVI system with a user-prompt device is also described.
