Specification Notes

[1] Zero-based, least-squares, straight line method.
[2] Typical value.
[3] Due to high sensitivity, the static pressure should be applied and removed very slowly. Rate should prevent more than 10 Volt change in output until Output Bias Voltage returns to normal (approximately 15 times discharge time constant).
