| Term | Definition |
|---|---|
| 動作範囲 | 単調な出力が観測できる最大範囲。 |
| リニアレンジ | The maximum range over which the deviation of the output from a linear best fit is within a specified percentage value. |
| 直線性 | The maximum deviation from a linear output as a percentage of the measurement range. |
| 再現性 | The maximum deviation in output when the sensor is tilted and then returned to its original position. |
| 決議 | The minimum incremental position change that generates a monotonic output. |
| 対称性 | The maximum deviation in output between two symmetrical positions on either side of null. |
| ヌル時の最大電流 | The maximum recommended current through the sensor at null at 23 °C which will not cause damage to the sensor. |
| ヌルインピーダンス | The impedance between the outer electrodes when the sensor is in the null position at 23 °C. |
| 動作温度 | The temperature range over which typical output behavior is observed. |
| 保存温度 | The temperature range that will not physically or chemically alter the sensor while it is not in use. |
| 24-Hour Stability | The maximum variation in sensor output over a 24-hour period while the sensor remains stationary at null. |
| ヌル温度係数 | The maximum output change at null per degree of temperature change above or below 23 °C. |
| スケール温度係数 | A coefficient to compensate for the change in gain caused by variations in temperature from 23 °C. |
| ヌルオフセット | The maximum deviation between the electrical null of the sensor and the mechanical null where the sensor is parallel to the surface of the Earth. |
| Cross-Axis Error | The maximum deviation of the output on one axis while tilting along the perpendicular axis. |
| 時定数 | The amount of time required for the sensor output to reach at least 63.2% of its final value. |
