Data Sheet  
40,000-Count Dual-Display Handheld LCR Meters  
Models 878B, 879B, and 880  
Features & Benefits  
nꢀ 40,000 counts resolution on primary and  
10,000 counts resolution on secondary display  
nꢀ L, C, R and Z (879B & 880 only) primary  
measurements  
nꢀ Automatic calculation of secondary parameters  
D, Q, θ, ESR (θ/ESR for 879B & 880 only),  
DCR (880 only)  
nꢀ Accuracy up to 0.1% and selectable test  
frequencies up to 100 kHz (880 only)  
nꢀ Fast auto range design for rapid, easy  
component measurements  
nꢀ Auto detect mode for automatic component  
type identification and measurement type  
selection (880 only)  
nꢀ Relative mode  
nꢀ Visible and audible tolerance mode  
nꢀ Data Hold and Min/Max/Average recording  
nꢀ USB (Virtual COM) interface  
nꢀ SCPI compliant commands for remote  
communication  
Full Featured Handheld LCR Meters  
The 878B, 879B, and 880 40,000-count  
handheld LCR meters measure inductance,  
capacitance, and resistance quickly and precisely.  
The 879B and 880 also measure impedance,  
Theta, and ESR. Additionally, the 880 offers  
capabilities typically only found in bench LCR  
meters such as a 4-terminal configuration, basic  
measurement accuracy up to 0.1 %, test  
ESR Measurements  
Models 879B and 880 have the ability to measure  
the ESR (Equivalent Series Resistance) of  
capacitors. ESR is the sum of in-phase AC  
resistance of a capacitor and used to rate a  
capacitor’s quality. An ideal capacitor would be  
lossless and have an ESR of zero. A capacitor  
could measure the correct capacitance value, yet  
still be defective, due to the component’s  
excessive in-phase AC resistance. The 879B and  
880 would be able to detect this faulty  
component.  
nꢀ Software for datalogging and front panel  
emulation available as free download  
nꢀ Configurable power-up-states  
n 3 year warranty  
Applications  
nꢀ Passive component troubleshooting  
nꢀ Electronic assembly  
frequencies up to 100 kHz, selectable test signal  
levels and measurement rate.  
nꢀ Quality control (component sorting)  
Fast auto ranging and quick measurement  
configuration such as measurement parameter  
and test frequency selection make these meters  
very simple to operate. The meters also include  
handy functions such as data hold, Min/Max/  
Average recording, tolerance sorting, and relative  
mode.
