Force Calibrator is designed to revalidate a loading system (UTM) or a hydraulic press from time to time. The system consists of a precision load cell / pressure transducer connected to the Force Calibrator, , which works on a single 9V battery with a 7 segment 10mm height, LCD display. To increase battery life a sleep mode has been incorporated. The indicator goes into a sleep mode if there is no change in reading beyond 5 counts within a span of 15 mins, thereby increasing battery life. The sleep mode can be revoked without any change in reading subject to load being held constant. The unit is factory calibrated using standards that has been calibrated in a national standards lab.
