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 10VDC calibrated value with a small (<~.5%) increase in uncertainty.
[1] Typical.
[4] -65 to +250 °F, ref. 75 °F (-54 to +121 °C, ref. 24 °C)
[5] Half-sine pulse duration, >= 20 µsec.
[1] Typical.
[6] 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.
[2] Verified with test data provided on supplied calibration certificate.
[7] Individually tested to ensure compliance with specified value.
[1] Typical.
