Why can't the clamp gauge measure the voltage and frequency?
- Band frequency may be the reason for increasing the cost and the market is limited. The theory is all right.s
Generator carbon brush sparks, how to deal with?
- From the following points: 1. check out whether the brush length is too short to cause the lifeline, the pressure is too small not brush contact ring; 2. check the spring pressure pressure is appropriate, if too small will lead to jump 3. check slip ring brush discharge; surface finish, if too much hair will increase the brush contact resistance of spark; 4. check the rotor electrical resistance, ensure the normal, no inter turn short; 5. check whether the oil bearing gap is too large, resulting in rotor slip ring brush runout, radial runout check slip surface is too large. The brush spark causes sparks; 6., whether the brush is the same as before, the brush has a requirement for the conductive current and the friction speed.s
What's the reason for the leak on the air conditioner? The pipes outside are changed, but the air conditioner is nearby
- Central air-conditioning settings are also very important. Hot customers home after open air conditioning, often want to step to set the temperature at 25 DEG C, if the air conditioning installation company to set reasonable, so even if the air conditioning on a set at 25 DEG C, but after the start but will be out of the wind, a little chilly, and then to gradually cooling the air outlet. The panel temperature decreases gradually, in order to adapt to the indoor temperature is higher, and will not be a step in the air outlet panel temperature drop caused by condensation.s
Digital caliper table GT201, pliers table GT201 how to use?
- The main function of the digital caliper meter GT201 is that it can conveniently measure the AC current value at work without having to connect any measuring liness
What is the voltage of the clamp table?
- The clamp type meter can not measure voltage by the way of clamp!s
How to auto discharge clamp current meter
- Clamp ammeters referred to as clamp meter.The work is mainly composed of an electromagnetic current meter and bushing type current mutual inductor. Straight through current transformer core made of movable opening, and a clamp on ammeter, named. The utility model is a portable instrument which can directly measure the alternating current of the circuit without disconnecting the circuit, and is very convenient for use in the electrical overhaul, and is widely used.s
A multimeter can measure AC current?
- A lot of clamp meter with measured resistance, DC voltage and other functions, simple, ordinary multimeter on the function can do a multimeter. Many measuring DC current clamp meter with the function, but most are used, instead of using pen clamp ring.s
How to use the 266CLAMPMETER clamp multimeter
- Before measuring, should first check whether intact core rubber insulated clamp. The jaw should be clean and free of rust, and there is no obvious gap after closure.s
