Q1: What is a LCR meter?
A1: LCR meter is also called LCR bridge or LCR tester. It can accurately and stably measure various component specifications, is a tester mainly used to test inductance (L), capacitance (C), and resistance (R). Digital LCR meter has two detection modes: series mode and parallel mode. The series mode is based on detection for component impedance Z, and the parallel mode is based on detection for component admittance Y. Digital LCR meter has the features of direct function and easy operation. It can meet test requirements of devices in production line quality assurance, incoming inspection, electronic repair and other industries with a lower budget.
Q2: What are the functions of LCR meter?
A2: The LCR tester is mainly used to measure the impedance of various electronic products, and can also measure the transmission performance of electronic components. In the actual measurement, there are many standard interfaces on the LCR tester, and the corresponding standard interface can be selected according to the situation of the electronic components to be measured, and the measurement can be performed automatically. The response time of this measurement is very fast, and the error is very small. The error of the current LCR tester can be less than 0.1%.
Q3: How does a LCR meter work?
A3: The measurement object of the digital LCR tester is the parameters of the impedance element, including the AC resistance R, the inductance L and its quality factor Q, the capacitance C and its loss factor D. Therefore, the digital LCR tester is often referred to as a digital LCR measuring instrument.
It is measured at frequencies from the power frequency to about 100 kHz. The basic measurement error is 0.02%, generally around 0.1%. Its impedance is represented by Zx, and Rr is a standard resistor. The switch can measure the voltages Ux and Ur respectively, so there is the following formula: Zx = Ux/Ix = Rr * Ux/Ur
This formula is a phasor relational formula. For example, the phase sensitive detector (PSD) is used to measure the in-phase component and quadrature component of Ux and Ur corresponding to a certain reference phasor, and then the analog-to-digital converter (A/D) converts them into digital quantities, and then The complex number operation is carried out by the computer, and the resistance value and reactance value that make up the measured impedance Zx can be obtained.
Tips: How to replace the battery of the handheld LCR meter?
- Use a Phillips screwdriver to remove the screws on the bottom case of the handheld LCR meter to open the bottom case.
- Remove the battery from the battery bay under the motherboard to replace it.
- The battery must be a standard model rechargeable lithium battery.
- Cover the bottom case and tighten it, the replacement is complete.
Note: If the portable LCR meter is not used for more than 3 months, or the external power adapter has been used for operation, please remove the battery to prevent the battery from leaking out of the corroded circuit board and damaging the digital LCR meter.
