2.4　成端接触电阻             仪器：dm－100b数字式微欧、微伏表
在正常大气条件下，导线与端子的成端接触电阻不大于3mω。
用dm－100b数字式微欧、微伏表接按图2、图3连接方法测试、测量设备的精度应使测量总误差不大于10%。
2.5　导线接线试验后接触电阻     仪器：dm－100b数字式微欧、微伏表
导线接线试验：用芯线直径为0.4mm的导线在同一个接线端子上，按规定次数（200次）反复接续，并用dm－100b数字式微欧、微伏表，按图2、图3连接方法测试第一次和最后一次接续的接触电阻，应符合下列要求：
a、第一次接续导线与端子的成端接触电阻不大于3mω；
b、导线接续试验后，即最后一次接续后接触电阻增值不大于2mω。

under the condition of normal atmospheric, wire and terminal intoωend contact resistance is not more than 3 m.
use of dm - 100 - b digital decay, microvolt table afterconnectedin figure 2, figure 3, the test methods and the accuracyof thetemperature measuring equipment shall be made to measure thetotalerror is not more than 10%.
contact resistance after the 2.5 wire connection test instrument:dm- 100 - b digital decay, microvolt table
wire connection test: use core wire is 0.4 mm in diameter, onthesame terminal number (200) according to regulations in placeofrepeatedly, and the dm - 100 - b digital decay, microvolttable,according to figure 2, figure 3, the connection method totest thefirst and the last time in the contact resistance, shallmeet thefollowing requirements:
a, for the first time in the wire and terminal into thecontactresistance is not more than 3 m ω;
b, wires succeeded after test, that is, the last time in placeofthe contact resistance value is not greater than 2 m ω.
