Page 3: General Characteristics And Safety Notice
I. General Characteristics and Safety Notice The 72-10465 LCR meter features an easy to read dual display measurement of 19999/1999. It also has serial and parallel measurement modes which can be used to select quality factor, loss factor, phase location angle, and equivalent resistance of measure articles. -

Measurement frequency “1kHz→10kHz→100kHz→100Hz→120Hz→1kHz”. 72-10465 can provide 5 frequency testing points, namely, 100Hz/120Hz/1kHz/10kHz/100kHz. Bootstrap default frequency is 1K and user can press “FREQ” key to select different frequency points for measurement of “1KHz→10kHz→ 100kHz→100Hz→120Hz→1kHz”. Note: DC impedance is measured under “AUTO DCR” mode and measurement frequency also can be neglected.

Calibration function includes short-circuit calibration and open circuit calibration. Short-circuit calibration can be adopted to reduce influence of contact resistance and testing wire resistance to measure low-impedance elements. Open circuit calibration also can be adopted to reduce influence of distributed capacitance and distributed resistance of testing wires to measure high-impedance elements.
