  • Page 19: Calibration

    ThePoint™ Series Installation Calibration ThePoint™ level measurement switch features both Auto- Cal and manual calibration. The standard Auto-Calibration mode is applicable to most liquids and slurries point level measurements. If preferred, the manual calibration can be used and is recommended for some application. ThePoint electronic unit has auto and manual calibration modes built into the standard unit and can be accessed through a simple routine (see section 2.8.5).
