1994 - MERLIN User\'s Guide

The use of the MERLIN for calibrating response-type roughness meters.

PLEASE NOTE: It is not recommended that MERLIN be used for roughness calibration. As a Class III roughness device, it gives an approximate estimate of roughness. It was developed at a time when there were few alternatives for calibration. It is only suitable when approximate estimates of roughness are required since it does not pick up all wavelengths and can lead to systematic mis-estimation of roughness. For proper calibration a Class I/II method must be used.
