  • 产品系列名称：BK878A通用LCR测试器
  • 产品定货号：ME-01879-00
  • 产地：法国
  • 品牌：SEFRAM
  • 推荐：
The 878A measures capacitance, resistance (of non-inductive components) and inductance. Components can be measured with selectable test frequencies in series or parallel modes as desired. The 4 1/2 digit main LCD displays values to 19,999, and the secondary 3 digit 1,000 count display reads D or Q. Both models can be used in either auto ranging or manual ranging modes.
 
Features
Selectable test frequencies 120Hz, 1KHz
Simultaneously displays measured component value and Q or Dissipation Factor (D)
Display hold
Relative mode
Tolerance mode
RS 232 Interface (cable and software required)
