BB2819XB Precision double-winding inductance tester LCR tester addition to all the test functions, it also has dual winding inductance measured simultaneously functions, and dual winding inductance for sorting or double winding inductance of the absolute difference for sorting. Meanwhile scalable signal interface access automatic production line for automated testing. It is particularly suitable for detecting the balance of the filter inductor. Features ● 20 * 2 dual line large character LCD display ● humanized operation interface, menu ● advanced test stability, accuracy ● Automatic, Manual, waiting measurement ● fastest measurement speed up to 20 times / sec ● five digits resolution, calibration function ● Automatic locking range ● most cost-effective instrument of its kind to test the fastest. ● Direct reading, upper and lower limits, the center value percentage relative deviation display mode ● four-terminal Kelvin test, sound, light automatic sorting function ● 10Ω, 20Ω, 50Ω, 100Ω, 2/50Ω five optional signal source output impedance parameters test parameters and display range Z, R, X 0.0001mΩ-999.99MΩ L 0.0001uH-99.999KH C 0.0001 pF -999.99 mF D 0.0001-9.9999 Q 0.0001-9999.9 θ-179.99o ~ 179.99o test frequency and accuracy 50Hz, 60 Hz, 75 Hz, 100 Hz, 120 Hz, 150 Hz, 200 Hz, 250 Hz, 300 Hz, 400 Hz, 500 Hz, 600 Hz, 750 Hz, 1KHz, 1.2 KHz, 1.5 KHz, 2 KHz, 2.5 KHz, 3 KHz, 4 KHz, 5 KHz, 6 KHz, 7.5 KHz, 10 KHz, 12 KHz, 15 KHz, 20 KHz, 25 KHz, 30 KHz, 40 KHz, 50 KHz, 60 KHz, 66.6 KHz, 75 KHz, 100 KHz, 120 KHz, 150 KHz, 200 KHz frequency of 38 ± 0.1% test voltage 0.1V ~ 1.1V, 10mV stepping test speed fast F: 20 times / second, the speed M: 5 times / second, slow S: 1 times / sec equivalent circuit in series / parallel test mode automatic, manual, wait until the measurement display mode direct reading, upper and lower limits, the center value percentage relative deviation display comparator function audible prompts, automatic sorting function clears way to open / Short Zero Range and automatically lock signal interface can be extended power range and power 50 Hz, 220V ± 10%; ≤ 30W Ambient conditions Temperature: 0 ~ 40oC, Humidity: ≤ 80% RH (40oC), pressure: 86 ~ 106KPa Dimensions and weight 320 * 320 * 100mm; approximately 4Kg
