¹ Exact output provided with calibration data. (Standardized outputs are optional). In addition, Strainsert factory calibrations are intended to simulate installed conditions, however, it is recommended that an in-place calibration be performed to account for any installation, tolerance, and/or alignment influences affecting sensor measurement. ² Prior to loading, it is necessary to initially/periodically null the zero load output to account for any residual offset.
