- Q: What is the range of temperature measured by thermocouples and thermal resistance?
- There are different types of thermocouple indexing, S platinum and rhodium (RH content 10%) pure platinum 0-1400 R platinum rhodium (RH content 13%) pure platinum 0-1400 B platinum rhodium (RH content 30%) platinum rhodium alloy (rhodium content 6%) 0-1400 K -200-+1000 T copper nickel chromium nickel silicon copper nickel copper nickel iron -200-+300 J -200-+600 N nicochrome silicon -200-+1200 E nickel chromium nickel silicon copper nickel tungsten rhenium 0-+2400 -200-+700The temperature range is 0-2400 degrees
- Q: What is the difference between the insulation resistance tester and the ground resistance tester, what's the general use of the three?,
- The two traditional testers are similar in shape, with a rocking handle and a pointer display window
- Q: How to measure the thermal resistance.I have a thermistor here, I wonder if I can use it, and I don't know how to measure it
- To accurately test, the use of high-precision constant temperature oil tank, if there is no such device, you can use multimeter at different temperatures to test the thermistor at both ends, and its resistance to change accordingly
- Q: Measuring method of resistance
- It can be said that most resistors have definite index indications, especially the larger volume resistance, the index is more clear and intuitive, and the smaller resistance index index may need simple conversion.
- Q: How does a multimeter measure the quality of a computer motherboard? How to repair it?
- Upstairs there is a copy, I'm helping you, ha ha!I think the maintenance is mainly used mainly uses is used to measure the impedance of Tuban to see understandOn a multimeter, it is difficult to repair the board, but also use oscilloscopes and other tools (mobile phone, forgive me, not too hard to say)
- Q: How does the 380V measure the voltage with a multimeter?
- One of the original electric phase, then the red pen is contacted to the measurement of the other phase, then the numerical three tables to support number is to measure three-phase power.The multimeter is also called the multiplex table, the multimeter, the three meter, the multiplication table and so on. It is an indispensable measuring instrument in the electric power and electronic departments. It is mainly used to measure the voltage, current and resistance. The multimeter is divided into a pointer multimeter and a digital multimeter according to the display mode. Is a multifunctional measuring instrument, multi range, general multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, some parameters can also be measured AC current, capacitance, inductance and semiconductor (such as beta) etc..
- Q: How to correctly use a multimeter to measure resistance in detail?
- How to correctly use the multimeter to measure the resistance of Yang Zhijun (Shanxi city of Yangquan province coal Vocational Education Center, Shanxi Yangquan 075800) Abstract: multimeter measuring instrument is a multifunctional, multi range, general measurement of current, voltage and resistance parameters, is a necessary instrument for electronic and electrical installation, commissioning and maintenance. And for electronic and electrical professional students. The correct use of multimeter has important significance. Based on years of teaching and practical experience, the author summed up the basic method of measuring resistance with a multimeter, and achieved good teaching results in teaching.
- Q: What is the principle of ground resistance meter and its measuring method?
- During the test, turning the handle according to the requirements of the speed tester through internal magnetic motor to generate electricity, the measured pile X and farther aided test pile (called Z) between "into" the current time in between the measured pile and X pile can obtain a Y auxiliary voltage meter by measuring the current and voltage values can be calculated by measuring the grounding resistance of the pile. The biggest difference between the ground resistance meter and the electrician's shake table is that the use is not the same. The two can not replace each other. There is no device that can always measure and display the size of the lightning protection, only by regularly testing your ground resistance.
- Q: What is insulation resistance tester?
- Measuring insulation resistance of various materials and transformers, motors, cables and electrical equipment, such as insulation resistance of the instrument, models are WD-3125, WD-3123 and so on
- Q: How to test the insulation resistance of the 10kV current transformer?
- Using 2500V insulation resistance measuring instrument (also known as insulated ohmmeter, including insulation shaking table), measuring the primary winding, the two winding, the end screen.
