This user guide provides background information on safety performance functions (SPFs) and the need for calibration. It also serves as a companion “how-to” manual for The Calibrator software tool. Installation Note: The Calibrator was developed for Microsoft Excel versions 2007 and later, running on Windows Operating Systems with the SOLVER add-in installed. Since the file includes macros, there may be warnings about enabling macros or Trusting the document before using it. Other issues that users may encounter include Trust Center settings. Users can access the Trust Center by navigating to (File, Options, and Trust Center). In the Trust Center options, click on Macro Settings and adjust according to your organizations policy. Microsoft also releases updates that can occasionally break ActiveX/Macros. Refer to your IT department about resolutions/hotfixes for ActiveX controls.
