FAQ


The Harms Caused by the Failure of Grounding from Instrument


In most measurement test systems, the nature of grounding can be basically divided into four categories:

1. Electrical grounding: Originally a conductive connection between the circuit and the earth. However, in the electronic equipment manufacturing industry, the meaning of the word has been relaxed to a point or points used as a zero voltage reference;

2. Power ground: Provide the return path of the current of the power required by the instrument;

3, the Signal Ground: all signal current reference point and return path;

4, Shielded Ground: usually the instrument's metal shell and cable shielding.


A good grounding system will reduce a lot of unnecessary troubles in measurement. The equipment and equipment must be properly used to ensure a good grounding. Good grounding has multiple purposes. The most demanding safety, and the pursuit of a stable circuit, are mainly The following points:


1. The machine is grounded. Under the condition of leakage, the instrument housing can not be charged and the use is safer;

2. Create a zero voltage reference point or a loop path for the integrated signals to achieve normal measurement purposes;

3, good grounding can effectively shield the interference of electric and magnetic fields, including external interference to the instrument, instrument power to the measurement of interference, the instrument to the outside interference
