RT527 Scope
This document describes the handling of calibration issues using the RT527
Sensor Control Board (SCB). This board is an optional board which contains
circuitry to support the reporting of auxiliary channel data, mass re-
centering and calibration signal output for two sensors. For more information
on sensor control see Section 8 in the 130 Theory of Operations.
