Notes:
¹ Possible resolution depends on the readout; the figures in Table 7 pertain to the GK-404.
² System Accuracy takes into account hysteresis, nonlinearity, misalignment, batch factor
variations, and other aspects of the actual measurement program. System Accuracy to ±1.0% FS
may be achieved through individual calibration of each strain gage.
Model 4200HT-T high temperature strain gage has a Thermal Coefficient of 17.3 µε/°C
