【Abstract】 In this article, the method for examining and repairing the FHD-1 proton nuclear spin magnetometer that no compensation electric current output, RS-232C bus isolated driver that makes data communication been on and off, water level, temperature data not been received, gas radon, helium instruments shut down without reason is introduced. The analysis on relative electric circuit and failures is also given. Examples are used for summarize the repair method, procedure and improving measures.更多还原
