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 frequencies up to 100 kHz, selectable test signal levels and measurement rate. 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. Measurement data can continuously transfer to a PC via the meter’s mini USB interface, using either the provided data logging software or SCPI commands sent from a custom program.

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. Applications n Passive component troubleshooting n Electronic assembly n Quality control (component sorting) |
