Specification Notes

[1] Zero-based, least-squares, straight line method.
[2] Typical.
[3] For +10 volt output, minimum 26 VDC supply voltage required. Negative 10 volt output may be limited by output bias.
[4] Two identically spec'd elements spaced 10cm apart - see drawing #65310 for details. Individual calibration certs supplied for each channel.
[2] Typical.
[5] See PCB Declaration of Conformance PS023 for details.
