| NOTES: |
| [1] |
1/4-28 has no equivalent in S.I. units. |
| [2] |
1Hz = 60 cpm (cycles per minute). |
| [3] |
Bias voltage increases with higher constant current. |
| [4] |
Conversion Factor 1g = 9.81 m/s². |
| [5] |
Maximum of 4 mA is recommended at temperatures above 250 °F (121 °C). |
| [6] |
See PCB Declaration of Conformance PS023 for details. |
| [7] |
The high frequency tolerance is accurate within ±10% of the specified frequency. |
| [8] |
Typical. |
| [9] |
Zero-based, least-squares, straight line method. |
