Notes:
1
Possible resolution depends on the readout; the figures in the above table
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 gauge.
3
Model 4200HT-T high-temperature strain gauge has a Thermal Coefficient of
17.3 / °C.
