The PRO8100 is available in two separate ranges which enable the instrument to read and display two units of measure. For ease of use, the operator has access to only six keys. The menu options offer the ability to tailor the instrument’s response to the application to easily select measurements like Gross, Net, Peak and Valley. An annunciator indicates which range has been selected. There is also a window to insert a legend that describes each range. Once these parameters are set, the window provides the user with a simple indicator.
