Model 878
Dual-Display Handheld LCR Meter
with Statistical Functions
The 878 measures capacitance, resistance, and induc-
tance. Components can be measured in the series and
parallel mode as desired. The full 4-digit display reads
values to 9999 on each range. The instrument is
autoranging; or manual ranging may be selected. The
instrument prompts the user when calibration is need-
ed, and the dual display shows whether to calibrate
with an open or short.
Model 875B
Low-Ohm LCR Meter
The rugged 875B LCR is a reliable easy-to-use workhorse that
will measure inductors, resistors and capacitors quickly and
accurately. Utilizing special circuitry, the measurement more
closely replicates true in-circuit measurements. Ten range resist-
ance range measures to 0.001 - zero adjust removes leads resist-
ance.
Model 815
Hand-held Component Tester
This handy capacitance meter (0.1 pF-20 mF) and ohm
meter (0.1Ω to 20MΩ) also tests: transistors, beta,
diodes, SCRs, LEDs and batteries. Use with TL-8 (shown
on page 90) for more effective testing.
