多功能频谱治疗仪是医院及家庭常用的理疗仪器。本文以FS84—16P型频谱治疗仪为例,说明其工作原理及常见故障检修。一、工作原理FS84—16P型频谱治疗仪电原理如附图所示。该机由电源、控制电路、频谱发生器等几部分组成。频谱发生器是该仪器的核心部件,它实际上就是一只带磁性的陶瓷发热管,靠其通电时产生的热能治疗 Multifunction spectrum therapy device is commonly used in hospitals and home physiotherapy equipment. In this paper, FS84-16P spectrum treatment instrument, for example, explain its working principle and common troubleshooting. First, the working principle of FS84-16P spectrum therapy instrument as shown in the figure. The aircraft by the power supply, control circuit, spectrum generator and other parts. Spectrum generator is the core components of the instrument, it is actually a ceramic heating tube with magnetic power generated by its heat treatment
