AB - The spatial variation of parameters such as temperature or flow velocity in a region of interest is frequently measured using scanning techniques and the results displayed on a chart recording. In certain instances it may be necessary to perform the scans manually using a time step procedure in order to maintain synchronism with the recording equipment. The sensor is moved in small equal steps with a fixed time delay at each location before moving to the next. Unless the delay is very much longer than the system time constant, including the sensor response, then time constant errors may result in the recorded measurements.This paper describes one of a number of techniques for correcting time constant errors incurred in these step scan systems. The method has the virtue of being simple to both understand and apply and sufficient background theory is included to convince the user that the approach is justified.
