1. Performance with offset, thermal accuracy of offset, and thermal accuracy of FSO compensation resistors. All values measured at 77°F
(25°C) and at 1.5 mA constant current or 10 VDC, unless otherwise noted.
2. Includes Linearity (BFSL), pressure hysteresis and repeatability errors.
3. 32°F to 158°F (0°C to 70°C) with reference to 77°F (25°C).
4. Consult factory for vacuum applications.
