N2 - The spatial electric field tester is mainly used for the measurement of high-altitude electrostatic field. The spatial electric field tester will be electrostatically charged during the period it is sent to a certain height by a micro-rocket. In order to study the charge characteristics, the paper analyzes the charging mechanism of the omni-directional spatial electric field tester and builds mathematics model for the friction charging, which is a main factor of the charging process. The numerical calculation and experimental research demonstrate that the friction introduces a slow charge accumulation process for the electric field instrument in the course of its campaign. Under the testing conditions in this paper, the charge amount is 10-11 C within the 6s duration. In order to improve the accuracy of the electric field measurement, a time-frequency analysis method can be adopted to remove the slow-varying electric field signal.
