1、测量的工频等效性好。振动仪测试电流波形为正弦波，使用两种频率进行测量。

1, the measuring frequency is equivalent. The vibrometer tests the current waveform as a sine wave, using two frequencies to measure. 

2、抗地电压干扰能力强。本仪器采用异频法测量，配合现代软硬件滤波技术，使得仪器具有很高的抗干扰性能，测试数据稳定可靠。15V工频（50Hz）干扰电压带来的误差仅为0.001Ω。

Strong resistance to geostatic voltage. The instrument is measured by hetero-frequency method, and with the modern hardware and software filtering technology, the instrument has high anti-interference performance, and the test data is stable and reliable. 15 v (50 hz) power frequency interference brought by the voltage error of only 0.001 Ω. 

3、精度高。可用来测量接地阻抗很小的大型地网。

3, high precision. It can be used to measure a large earth net with a small grounding impedance. 

4、功能强大。可测量相关标准规定的接地装置的全部特性参数。不仅可测量接地阻抗，还可测量出电阻分量和电抗分量。

Powerful. All characteristic parameters of earthing device that can be measured by relevant standard. Not only can the ground impedance be measured, but also the resistance components and the reactance components can be measured. 

5、具备断线报警功能，避免了错误测量。

Have broken line alarm function, avoid error measure. 

6、操作简单。全中文菜单式操作，直接显示出测量结果,且自带微型打印机可现场打印测量结果。

Simple operation. Full Chinese menu operation, directly display the measurement results, and bring the microprinter to the field to print the measurement results.
