How to avoid LCR table corruption

Many people know what the LCR meter is used for, and they know the type and brand of the LCR meter and how to operate it. However, how to avoid common failures of LCR watches and how to operate LCR watches safely? Next, please listen to Xi'an Antai test popular science, I hope it will be helpful to everyone!

First of all, the LCR meter, as the name suggests, is a special measurement tool used to measure the intrinsic parameters of electrical components. L refers to the inductance, c refers to the capacitance, and R refers to the resistance. LCR meters cannot measure other meters. Inductance, resistance or capacitance should be measured when the circuit is powered off. Since it is a special instrument, the measurement accuracy is high and the accuracy is high.

So how to operate and use it correctly? What about the LCR table? How can I avoid damage? Common fault phenomena in the use of LCR meters are as follows:

1. Power failure: unable to start normally

2. Input failure: abnormal impedance; no signal; abnormal signal amplitude

3. Test analysis fault: frequency: phase test abnormality

4. Display failure: colorful screen; black screen;

5. Button failure: the button does not respond; the adjustment knob does not respond;

6. Interface failure: storage media not recognized; unable to contact the control system

7. Other usage issues, etc.

How to avoid the above failures?

Make sure the grounding is correct

1. The three-phase AC power cord attached to the instrument must be used.

2. Proper grounding prevents static electricity that is harmful to the instrument and operators.

3. Do not use lead wires without protective grounding conductors, which will cause grounding protection to fail. Power cords or autotransformers.

4. Check the quality and polarity of the AC power supply before use. The voltage used by the instrument is generally 100V, 120V, 220V (error ±10%) or 240V (error +5%/-10%). The typical ground resistance value is Ω, the voltage is V between the neutral line and the ground line, and an uninterruptible power supply [UPS] may be required if necessary. Can you use it? it's actually really easy.
