The PSD is a completely portable strain gauge transducer battery powered indicator, packaged in a small, robust IP65 / NEMA 4 enclosure. For simplified use, the operator only has access to six keys. Two separate ranges are available, which enable the instrument to read and display two units of measure. The menu options offer the ability to tailor the instruments response to the application. Gross, Net, Peak and Trough measurements are easily selected. An annunciator indicates which range has been selected. There is also a window, to insert a legend, describing each range. Once these parameters are set, it provides the user with the simplest of indicators.
