FAQ

Why is double speed motor low speed r current and high speed current?
Two speed motors should be of low speed, high speed and small current when carrying the same load.5) there is a point, later ask questions, please describe a smooth, do not be so hasty, if it is not to see Chen always back to you, I do not want to answer.
Current and power conversion of clamp type meter
Single phase 220V circuit, current, *220= power.
What is the difference between the clamp meter and the universal table?
Clamp meter for measuring the line current in the continuous line condition.
Can you direct the direct current with the pliers jaw (not measuring pen)?
A table can only be induced to AC, DC can not be measured. Measuring DC with a multimeter
How to measure the motor current with a multimeter?
Measurement of alternating current. The measuring method is the same as that of 1, but the gear should be switched to the AC gear. After the current measurement is completed, the red pen should be inserted back into the "V" hole.If the measuring range is enough, measure according to the above method. Does not recommend the use of multimeter with clamp current meter to measure the motor current recommendations. Safe and convenient.
How to use the multimeter to check the grounding wire is normal?
It is easy to detect by the clamp type meter, without the ground wire being disengaged, but the actual test is impedance. If the earth wire has current, the error of detection will be greater.
Air conditioning suddenly does not cool down, what's the matter?
Air conditioning is not one of the reasons for refrigeration: Freon is not enough (commonly known as lack of snow) solution: add freon, that can solve the problem of air conditioning is not refrigeration.
Electric drills, electric saws and so on. Under what circumstances should carbon brushes be used?
A carbon brush is used whenever a point drill or an electric saw is used. It is a device that transmits energy or signals between a stationary part of a motor or other generator or other rotating machine;
