在组装和使用TY-360trx型指针式万用表的过程中，发现直流电流档出现测量中断或烧坏表头，交流电压测量出现较大误差等现象。研究发现这些现象的产生源于电路结构和参数设置的不合理。于是将直流电流测量电路改造成环形电路结构，交流电压测量电路改造成独立分压结构，并且都重新设置电路参数。万用表经这样的设计改造，能提高其使用的可靠性，减小测量误差。

In the process of assembling and using TY-360tRx type analogue meter, dc current file appears to interrupt or burn out headers to measure, and ac voltage measurement appears big error. The study finds that these phenomena resulting from the appearance of the circuit structure and parameters of the set are not reasonable, So the direct current measurement circuit is transformed into the ring circuit structure, and the ae voltage measurement circuit is transformed into independent points pressure structure, and all circuit parameters are reset. The design and transformation of such a multimeter can imorove the reliability of its function and reduce errors.
