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.
