Abstract
A system and method is provided to measure a pressure or other characteristic at a source (e.g. a hydraulic power supply) and in or near a downhole tool. A comparison of the measurements is then made to verify that the system is operating according to desired parameters. In specific applications, the comparison can be made to ensure the supply of hydraulic fluid is reaching the downhole tool.
