Notes:
1 Other ranges available on request.
2 Other capacities available on request. Calibrations that exceed geokon’s NIST traceable capacity of approximately 10,675 kN are subcontracted to an accredited testing laboratory.
3 The accuracy of the testing machine used to calibrate the cells is ±¼% F.S. traceable to NIST. The system accuracy depends on end loading conditions as described in the text of this manual. If field conditions are well duplicated during actual calibration the accuracy should be within ±5 F.S. Failure to duplicate conditions can cause calibration variations of ±20% in extreme cases.
4 Minimum, depends on the readout instrument and technique.
5 Repeatability under the same loading conditions. This does not take into account hysteresis and any changes in the loading conditions.
6 With no calibration shift. The maximum overrange without failure is 200% F.S. for aluminum cells, 300% to 400% F.S. for steel cells, but both the no-load zero and the calibration may change if the load exceeds 150% F.S.
