1 Scope

GB/T 13823 provisions of this part of the Earth's gravity on the use of accelerometers is absolutely required for calibration and operation of equipment program.

This section applies to linear accelerometers with zero frequency response (mainly strain gauge or piezoresistive), servo accelerometers, including standard transmission Sensors and sensor work.

This part of the use of positive and negative local acceleration of gravity as the standard value of 0Hz.

This section allows uncertainty limit is ± 0.01m/s2.

3 Equipment Requirements

4 Preferred value

During calibration, you should use the local gravitational acceleration due to the Earth's gravity caused by positive and negative values \u200b\u200b(in m/s2 representation).

Note. The output is often difficult due to the Earth's gravitational component caused due to transverse sensitivity and output areas due to separate, it is caused by the Earth's gravitational component of gravity Positive negative acceleration value between the calibration is not feasible.
