1、将接地电阻测试仪放置水平位置，检查检流计的指针是否在中心线上，否则应用零位调整器将其调整于中心线上。大电流发生器为低电压、大电流干式变压器。适用于频率50HZ开关，电流互感器或其他电器设备的升流及负载试验。

1, place the grounding resistance tester, a horizontal position, check whether the galvanometer pointer is on the center line, otherwise the application of zero adjustment regulator will be in the center line. Big current generator for low voltage, high current dry type transformer. Suitable for frequency 50 hz switch, current transformer or other electrical equipment of riser and load test. 

2、将“倍率标度”置于最大倍数，慢慢转动发电机的摇把，同时转动“测量标度盘”使检流计的指针指于中心线上。

2, puts the ratio scale biggest multiples, slowly rotate the winder handle generator, turn the dial "measurement" at the same time make galvanometer pointer refers to the center line. 

3、当检流计的指针接近平衡时，加快发电机摇把的转速，使其达到每分钟120转以上，同时调整“测量标度盘”，使指针指于中心线上。

3, when the galvanometer pointer close to balance, accelerate the generator rotational speed of crank, bringing it up to more than 120 revolutions per minute, adjust the "measuring dial" at the same time, make pointer refers to the center line. 

4、如“测量标度盘”的读数小于1时，应将倍率置于较小的倍数，在重新调整“测量标度盘”以得到正确的读数。

4, such as measuring dial reading less than 1, the ratio should be in multiples of smaller, readjust dial "measurement" to get the correct reading. 

5、在填写此项记录时，应附以电阻测试点的平面图，并应对测试点进行顺序编号。

5, when fill in the record, should be attached to the plan of the resistance test points, and shall be carried out to test points are numbered sequentially. 

接地电阻测试仪注意事项

Grounding resistance tester 

1、接地线路要与被保护设备断开，以保证测量结果的准确性。

1, grounding line should disconnect with the protected equipment, to ensure the accuracy of measurement results. 

2、下雨后和土壤吸收水分太多的时候，以及气候、温度、压力等急剧变化时不能测量。

2, after the rain, and soil absorbs water too much, and sharp changes such as climate, temperature, pressure cannot be measured. 

3、被测地极附近不能有杂散电流和已极化的土壤。

3, measured near the ends of the earth, there can be no stray current and polarization of the soil. 

4、探测针应远离地下水管、电缆、铁路等较大金属体，其中电流极应远离10m以上，电压极应远离50m以上，如上述金属体与接地网没有连接时，可缩短距离1/2~1/3。

4, probe should be far away from the underground pipes, cables, railway, and other large metal body, the current should be far away from the more than 10 m, voltage should be far away from more than 50 m, such as the metal body and ground net.through no connection, can shorten distance 1/2 ~ 1/3. 

5、注意电流极插入土壤的位置，应使接地棒处于零电位的状态。

5, pay attention to the position of current pole inserted into the soil, should make the grounding rods in a state of zero potential. 

6、连接线应使用绝缘良好的导线，以免有漏电现象。

6, good conductor cable insulation should be used, so as not to have leakage phenomenon. 

7、测试现场不能有电解物质和腐烂尸体，以免造成错觉。

7, test site cannot have electrolytic material and rotting corpses, lest cause illusion. 

8、测试宜选择土壤电阻率大的时候进行，如初冬或夏季干燥季节时进行。

8, test time of the appropriate choice of soil resistivity, such as winter or summer dry season. 

9、随时检查仪表的准确性，（每年送计量单位检测认定一次）。

9, check up the accuracy of the instrument, at any time (send the measuring unit testing that once a year). 

10、接地电阻测试仪在使用、搬运、存放时应避免强烈震动。

10, grounding resistance tester, when using, handling, storage should avoid strong vibration.
