利用惠斯通电桥的原理对欧姆表进行了改进，改进后的欧姆表的读书符合初学者从左往右读数的习惯，表笔的接法与电流表、电压表相同，每次换倍率时，不需要再调零，且具有测量范围大、误差小等特点。
利用惠斯通電橋的原理對歐姆錶進行瞭改進，改進後的歐姆錶的讀書符閤初學者從左往右讀數的習慣，錶筆的接法與電流錶、電壓錶相同，每次換倍率時，不需要再調零，且具有測量範圍大、誤差小等特點。

Ohmmeter was improved based on the principle of Wheatstone bridge .The connection of the improved ohmmeter was the same as that of ammeter and voltmeter ,and it could be read from left to right ,in accordance with tyros’ habit .It was not necessary to adjust zero when changing the scale .It also had the advantages of large measurement range and small error .
