Device Calibration Checks. The actuators or devices listed below were checked for calibration. This is a <br />spot check On a sample of the calibrations done during field verification checklist and startup. <br />"In calibration" means observing readout in the BAS and going to the actUator or controlled device and verifYing thai the BAS <br />reading is correct. For items oul of calibration or adjustment, fix now. if easy, via an offset in the BAS. or a mechanical fIX. <br /> <br />Device or Actuator & Location 1st Site Final BAS Pass <br /> Procedure I State BAS Value Observation Reading Y/N <br />DX cooling stages control I.
