- 产品名称：BK878ABK878A通用LCR测试器
- 定货号：DI-00094-00
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)
