Impact Technology provides accredited calibration services for a variety of instrumented tups. This work is a cooperative effort between United Calibration Corporation ( IAS accredited laboratory) and Impact Technology. Contact Us regarding a quotation for tup calibration.


The calibration is for longitudinal axial load application to the instrumented tup. A reference load is applied to the tup and the output value of millivolts per volts (mV/V) is recorded. A series of reference load and output value pairs are obtained over a load range of 5 to 100 percent of tup capacity. Statistical regression techniques are used to determine the best linear fit to the resultant data. A precision resistor is shunted across the tup strain gauge circuit and the tup output value of mV/V is recorded.


The calibration testing is performed by United Calibration Corporation with the Impact Technology procedure for application of reference load and tup output recording. The certificate of calibration report for the resultant data, includes shunt tup output and tup excitation voltage. United Calibration Corporation has demonstrated compliance with ANS/ISO/IEC Standard 17025:2005 "General Criteria for the Competence of Testing and Calibration Laboratories".

Impact Technology performs the statistical evaluation of the data contained in the certificate of calibration report and prepares a calibration summary report  for each tup. This report presents tabulated and graphical data for tup output (mV/V) as a function of applied reference load (kN).  The  tup shunt  output value is used to determine the Dynatup® Calibration Factor in force units.
