Specification Notes
[1] Typical.
[2] Verified with test data provided on supplied calibration certificate.
[3] Sensitivity is proportional to excitation voltage, and at other excitation values, sensitivity can be predicted from the 5VDC calibrated value with a small (<~.5%) increase in uncertainty.
[1] Typical.
[4] Half-sine pulse duration, >= 20 µsec.
[5] Settling Time is the maximum time after power-up for the Offset Voltage to be within +/-2% of Measurement Range output of the final offset value. Mounting surface must be at thermal equilibrium.
