Data Sheet

Models 878A & 879

LCR Multimeters

The 878A and 879 measure 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 (100Hz & 10KHz model 879 only)

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

- Display hold

- Relative mode

- Tolerance mode

- Backlight (model 879)

- RS 232 Interface (cable and software required)
