Data Sheet 40,000-Count Dual-Display Handheld LCR Meters Models 878B, 879B, and 880 Features & Benefits n 40,000 counts resolution on primary and 10,000 counts resolution on secondary display n L, C, R and Z (879B & 880 only) primary measurements n Automatic calculation of secondary parameters D, Q, , ESR (/ESR for 879B & 880 only), DCR (880 only) n Accuracy up to 0.1% and selectable test frequencies up to 100 kHz (880 only) n Fast auto range design for rapid, easy component measurements n Auto detect mode for automatic component type identification and measurement type selection (880 only) n Relative mode n Visible and audible tolerance mode n Data Hold and Min/Max/Average recording n USB (Virtual COM) interface n SCPI compliant commands for remote Full Featured Handheld LCR Meters ESR Measurements The 878B, 879B, and 880 40,000-count Models 879B and 880 have the ability to measure communication handheld LCR meters measure inductance, the ESR (Equivalent Series Resistance) of n Software for datalogging and front panel capacitance, and resistance quickly and precisely. capacitors. ESR is the sum of in-phase AC emulation available as free download The 879B and 880 also measure impedance, resistance of a capacitor and used to rate a n Configurable power-up-states Theta, and ESR. Additionally, the 880 offers capacitors quality. An ideal capacitor would be n 3 year warranty capabilities typically only found in bench LCR lossless and have an ESR of zero. A capacitor meters such as a 4-terminal configuration, basic could measure the correct capacitance value, yet Applications measurement accuracy up to 0.1 %, test still be defective, due to the components n Passive component troubleshooting frequencies up to 100 kHz, selectable test signal excessive in-phase AC resistance. The 879B and n Electronic assembly levels and measurement rate. 880 would be able to detect this faulty n Quality control (component sorting) component. Fast auto ranging and quick measurement confi guration such as measurement parameter Specifications 878B 879B 880 and test frequency selection make these meters Measurements L, C, R, D, Q L, C, R, Z, D, Q, , ESR L, C, R, Z, D, Q, , ESR & DCR very simple to operate. The meters also include Basic Accuracy 0.5% 0.5% 0.1% handy functions such as data hold, Min/Max/ Average recording, tolerance sorting, and relative 100 Hz, 120 Hz, 100 Hz, 120 Hz, Test Frequency 120 Hz, 1 kHz 1 kHz, 10 kHz 1 kHz, 10 kHz, 100 kHz mode. 0.3 Vrms, 0.6 Vrms, 1 Vrms Test Signal 0.6 Vrms 0.6 Vrms DCR: 1 Vdc Measurement data can continuously transfer to Backlit Display - a PC via the meters mini USB interface, using Auto Detect Mode - - either the provided data logging software or SCPI Tolerance Mode 1%, 5%, 10% 1%, 5%, 10%, 20% 1%, 5%, 10%, 20% commands sent from a custom program. 4 readings/sec (fast), Measurement Rate 1.5 readings/sec 1.5 readings/sec 1.5 readings/sec (slow) Technical data subject to change www.bkprecision.com B&K Precision Corp. 202040,000-Count Dual-Display Handheld LCR Meters Models 878B, 879B, and 880 Easy Front Panel Operation Calibration function for improved Primary display mode L/C/R and Z (879B only) measurement accuracy Secondary display mode D/Q// Secondary display mode D/Q, /ESR (879B only) ESR, selectable test level 878B & 879B 880 LCD protective visor 10,000-count secondary display 40,000-count primary display Backlight function (879B & 880 only) Selectable test frequencies Primary display mode L/C/R/Z/DCR, single push auto detect function Standard mini USB port Guard terminal for better noise immunity 4-terminal test socket plus guard terminal allows for direct 2-terminal test socket plus guard terminal allows for direct measurement of leaded components or use with test fixture measurement of leaded components or use with test fixture Calibration function for improved Selectable measurement rate measurement accuracy 2 www.bkprecision.com
