Data Sheet
Model 878A
Dual Display Auto Ranging LCR Meter
Model 879
Deluxe Dual Display Auto Ranging LCR Meter
The 878A and 879 measure capacitance, resistance (of non-inductive components) and
inductance. Components can be measured with selectable test frequencies in series or paral-
lel 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)
