LCR tester HP4275A HP HP4275A
Used LCR tester HP HP4275A function: HP HP4275A bridge details: LCR tester HP HP4275A offer:
HP4275A LCR bridge can quickly measure inductance L, capacitance C, resistance R and loss factor D, quality factor Q, conductance G, susceptance B, reactance X | Z | and vector impedance and phase Angle theta,
Its frequency range is 100Hz to 100kHz with 13 optional frequency test points.
The test voltage range is 1mV ~ 5VRMS, which is suitable for many measurement requirements of circuit design, product experiment and quality inspection.
This variable test signal provides great convenience for measuring nonlinear impedance components such as inductors and semiconductor devices.
The meter measures values in two parts 4? Digital unit display, and can be every 10 measurements after the average value of 5? Digital display. In addition, it also provides a signal when testing components
Voltage and applied current 3 digit display, in order to monitor the test voltage, current situation.
The meter has a capacitance test range of 0.01FF to 1999.0MF (1 millipicofarad =10-15 farad), an inductance of 0.001NH to 1999.9H, and a resistance and impedance of
0.001 m Ω Ω ~ 19.999 m. All measurements are accurate from 0.1% to 10%, depending on the voltage and frequency of the test signal.
The measuring circuit can be in either parallel equivalent circuit form or series equivalent circuit form.
The meter can be automatically calibrated to reduce stray capacitance to 20pF, parasitic inductance to 2000nH, resistance to 0.5Ω, and conductivity to 5μs. Frequency range: 100Hz-100KHz
