我厂根据工矿企业和科研单位对电容、电感、电阻元件进行精密测量的需要,在兄弟单位支持下,试制成功了 QS—72型精密万用电桥。其精确度和测量范围均比现行生产的QS—18型万用电桥优越。QS—72型精密万用电桥是一种多用途的阻抗电桥,适用于元件的精密测量,可以测量电感、电容、电阻,也可测量电容器的损耗因数和电感的 Q 值。
I plant according to industrial and mining enterprises and research institutes on the capacitance, inductance, resistance components for precision measurement needs, brothers units in support of the successful trial of the QS-72-type precision universal bridge. Its accuracy and measurement range than the current production of QS-18-type multi-purpose bridge superior. The QS-72 Precision Multi-Purpose Bridge is a multipurpose impedance bridge that is suitable for precision measurement of components. It measures inductances, capacitances and resistances. It also measures the dissipation factor of capacitors and the Q of the inductor.
