代理美国AVO绝缘电阻测试仪BM100/4价格-绝缘电阻测试仪-绝缘测试仪原理-型号-参数

• Suitable for testing to the IEE Wiring Regulations • Complies with the requirements of BS 7671, HD 384 and IEC 364 • Combined insulation and continuity testing • Insulation testing at 500 V d.c. to the VDE 0413 Part 1

The MEGGER BM100/4 and BM101/4 Insulation and Continuity Testers provide an insulation test voltage of 500 V d.c. The instruments have two continuity measuring ranges: 0 to 2 Ω and 0 to 200 Ω . The instrument has an automatic voltage indicating facility that warns, before a test is executed, if the instrument has been inadvertently connected to an energised supply. This warning is given by a reading on a 0 to 600 V a.c. scale on the meter; this scale also monitors the discharging voltage following tests on a capacitive circuit. The BM101/4 does not have the voltage indicating facility, but instead has an additional resistance range of 0 to 1 MΩ.
