Abstract A miniature field meter is described for measuring fair weather electric fields (of magnitude ~100 Vm-1). It is a brushless field mill constructed from machine-cut parts, driven by a computer fan motor. It resolves fair weather fields at ~1 mV per (Vm−1), with a time response of 0.65 s. It implements self-calibration through combining a mechanical shutter with a programmable bipolar calibration electrode. It has a mass of 86 g, dimensions 4 cm × 4 cm x 8 cm and consumes

大气科学平台的晴天电场计

摘要 描述了一种用于测量晴天电场（幅度 ~100 Vm-1）的微型场计。它是一种无刷现场研磨机，由机器切割零件构成，由计算机风扇电机驱动。它以每 (Vm−1) 约 1 mV 解析晴朗天气场，时间响应为 0.65 s。它通过将机械快门与可编程双极校准电极相结合来实现自校准。它的质量为 86 g，尺寸为 4 cm × 4 cm × 8 cm，消耗
