Specification Notes

[1] Zero-based, least-squares, straight line method.
[2] Typical.
[3] For +10 volt output, minimum 24 VDC supply voltage required. Negative 10 volt output may be limited by output bias.
[4] 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).
[5] -5V output may be limited by the output bias.
[2] Typical.
[6] See PCB Declaration of Conformance PS023 for details.
