产品名称：LCR测试器
定货号：DI-00095-00

推荐：

The 879 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 100Hz, 120Hz, 1KHz, 10KHz

Simultaneously displays measured component value and Q or Dissipation Factor (D)

Display hold

Relative mode

Tolerance mode

Backlight

RS 232 Interface (cable and software required)
