(2)
Total Error Band is the sum of worst case linearity, repeatability, hysteresis, thermal effects and calibration errors over the operating temperature range.
Full scale for differential ranges is the sum of + and – ranges. Calibration is traceable to NIST.
(2)
Exposure to overpressure will not permanently affect calibration or accuracy of unit. Burst pressure is the sum of the measured pressure plus
the static pressure and exceeding it may result in media escape.
(3)
User configurable.
(4)
Recommended load impedance of 100 k-ohm or greater.
