And shake the electrical insulation resistance measurement, and its value is not lower than 50 megohm. 然后摇测电机的绝缘电阻，其值不低与50兆欧。

The tester not onlytestes the milliohm and megohm resistor of cable,but also pro-vides a solution to the cable design , manufacture and test. 该测试仪不仅可以测量电缆线束的毫欧级电阻和绝缘性能,而且可给电缆的设计、生产和检测提供一个一体化的管理手段。

Pump before use application megohm table to check the electrical insulation resistance the minimum value of not less than 5 megohm. 电泵在使用前，应用兆欧表检查电机绝缘电阻，其最低值不能小于5兆欧。

Megohm inspection method is to form a terminal connected to the electric cable line, another terminal connected to the motor casing, the shake table megohm observed value of insulation resistance. 检查方法是将兆欧表上的一个接线柱接在电泵电缆线上，另一接线柱接在电机外壳上，摇动兆欧表，观察绝缘电阻值。

Megohm inspection method is to form an electric cable terminal at the online access, another access terminal on the motor casing, megohm shake table to observe the value of insulation resistance. 检查方法是将兆欧表上的一个接线柱接在电泵电缆线上，另一接线柱接在电机外壳上，摇动兆欧表，观察绝缘电阻值。
