The licensee shall maintain, check and calibrate equipment to ensure that the equipment is giving results compatible with its intended use and achieving the precision that is required, or is reasonably expected by the client.
When retracing an earlier survey, a licensee shall consider the capabilities of the equipment used to obtain original measurements insofar as that information is known or should be reasonably known to the licensee and may affect the re-establishment of any corner or boundary.
When monumenting or marking boundaries, the licensee shall use equipment that will give reliable precision.
