- Q: Can the multimeter of the multimeter be used for measuring insulation resistance?
- Yes, but it depends on how much insulation you measure. If the insulation value is too large, the data measured by the meter cannot be accurate, and the data size can not be measured accurately
- Q: How to measure the insulation of generator?
- But now a general point of power plant are electronic shake table, do not need to shake, the same is set up according to the basic parameters on the surface, the shaking table, can be said to be a fool, such as the measurement of grounding resistance, grounding E G (P) is connected to the device. Finally, just press a button can be measured after.60 seconds can be measured to 15 seconds and 60 seconds. The resistance resistance will automatically give you calculate the absorption ratio, and print it out!
- Q: What are the problems that should be paid attention to when measuring temperature with temperature measuring parts, thermocouples or thermal resistors?
- It shall be used according to the environment and atmosphere provided by the thermocouple and the thermal resistor, otherwise the service life and accuracy will be seriously affected.The temperature limit of the temperature field to be measured should be close to the upper limit of the measurement range, such as the long-term work at the upper limit of the measurement range, it may affect the life of 2/3.
- Q: Where can I measure the varistor? I am digital multimeter 200, Europe forward and reverse measurement of him (non charged), only shows 1. Does that mean he's good? Can you live test?
- The method of the current source and the multimeter accuracy is very high, and because of the influence of various aspects, often is not very accurate, in addition, we must control the test time, test is completed within 5S, and the shorter the better. Can make temporary judgments, do not recommend long-term use.
- Q: A measuring instrument for the resistance of wires.
- The most economical and reliable way is to use both arms bridge, QJ44, QJ57 can.
- Q: The earth resistance tester is an instrument for measuring the insulation resistance of a line, isn't it?
- No, the grounding resistance tester is applicable to electric power, telecommunications, railways, communications, mining and other departments to measure the grounding resistance of various devices and measuring low resistance conductor resistance, but also the soil resistivity measurement instrument and voltage.
- Q: Measurement of thermal resistance
- Test the resistance in the indoor environment first, then hold the product test with your hand to see if the resistance is small, if the change shows normal, otherwise it is not normal.Note: when testing, accurate measurements should be made with specialized instruments.
- Q: How can the resistivity meter survey be solved?
- If the measurement is not accurate, the reason is estimated as follows: 1- probe part or 2- instrument host circuit part.If have another normal instrument, judgment methods: 1- the original instrument probe connected to another Taiwan Normal measuring instrument host, if this measurement is normal, the probe part of the original instrument is normal. Estimation is part of the original instrument host circuit instrument problems; or 2- will be another measurement of normal instrument probe, connected to the original instrument on the host, if this measurement is normal, indicating the host circuit part of the original instrument is normal. It is estimated that the probe part of the original instrument has a problem.
- Q: The working principle of measuring resistance by DC bridge
- The value of the resistor allows no current to pass through the G. The bridge is balanced and the unknown resistance is R2=R1 = R4/R3.Whisden Wheatstone bridge DC Wheatstone bridge is the most basic. Its working principle: suppose four resistor is fixed, when the S is closed, if satisfied: "R3*R2=R1*R4", is equal to the product of the diagonal resistance, then Ucd equals 0, CD is no voltage. Using this principle, when both sides four volume etc. a time for the unknown, if the regulation of the remaining three resistance value can make the equation set up, then use the formula to get the unknown. But in fact as long as the equation on each side of a variable resistor can be adjusted, so the other two resistance is a fixed value, then another it can be obtained.This principle can be used as a resistance measuring box. This principle uses the concept of "bridge", or "balance bridge"
- Q: What's the difference between a ground resistance tester and a shake meter?
- The grounding resistance of the grounding test device of GY-318 double jaw grounding resistance tester is applicable to all kinds of equipment and building the. The soil resistivity under various conditions can also be measured. In addition to the traditional function of measuring the grounding resistance of the earth electrode, the instrument has the unique function of non auxiliary pole measurement, and has changed the traditional measuring principle and means of the test grounding resistance.
