NOTES:
[1] Verified with test data provided on supplied calibration certificate.
[2] Settling Time is the maximum time after power-up for the Offset Voltage to be /-2% of
Measurement Range output of the final offset value. Mounting surface must be at thermal
equilibrium.
[3] Individually tested to ensure compliance with specified value.
[4] Half-sine pulse duration,
≥
20 µsec.
[5] Typical.
[6] -65 to +250 °F, ref. 75 °F (-54 to +121 °C, ref. 24 °C)
[7] 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.
