FAQ

Current and power conversion of clamp type meter

Single phase 220V circuit, current, *220= power.

How to maintain and maintain the communication and power room?

The quality standard of power supply should be uninterrupted to the communication equipment. First of all, the quality of power supply should be guaranteed to meet the standard. In the regulation of telecommunication power supply maintenance China Telecom "(hereinafter referred to as the" Regulations "), the DC power supply voltage, DC power supply circuit connector (outside the joint pressure drop distribution screen, DC) the parameters of voltage, power supply standard AC mains power and AC power supply in the oil machine noise voltage, frequency and power factor so do the detailed requirements. At the same time, the regulations also specify the parameters such as three-phase supply voltage unbalance, voltage waveform, sine distortion rate and so on. From the above standard requirements, we can see that in the test of daily power supply quality

Clamp ammeters on what hold is

The measured current is dynamic, so the digital clamp meter has been beating, press hold, can make the digital positioning in the moment of the current value of the press.

What is the connection between the distribution box and the bridge?

May and the use of electric welding machine, wire welding machine in which a random metal pipe, when welding welding current welding wire through a plurality of left back, in a weak point there will be a great current, have a fever.

But after 3 minutes on the machine, there is no electricity, what's the matter?

At first glance, under cooling state, adjust the temperature controller to the user, set the temperature 6 degrees lower than room temperature time temperature to 8 DEG C in 15 minutes after running, the normal air conditioning in the indoor machine hydraulic pipe should be no frosting phenomenon, if this phenomenon if there is leakage of fluorine failure. If there is a hydraulic pipe connector of indoor machine oil, which also shows that air conditioning has produced fluorine leakage phenomenon.Followed by touch, touch the air conditioning after the condenser shutter fan, if the hand temperature is not changed, and the compressor at work, which means that the fluorine has been run. Because the compressor is working, there is no heating or cooling.If you find that the compressor has been working since it started, there is no vibration of the compressor, and the sound of the compressor self shock is larger than that of the newly purchased air conditioner. This may be the abnormal sound caused by leakage of fluorine.Finally, temperature measurement. Find a thermometer, close to the air outlet, look at the thermometer indicates whether 6 to 8 DEG C lower than room temperature, as shown in the temperature lower than the indoor temperature less than 5 degrees even at room temperature and not much difference between, continues and the compressor work, it shows that air conditioning fluoride may have leaked.

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.

How to use vc3266l type electric pliers

AC voltage measurement(1 function switch is placed in 600y - file).(2) the black pens are respectively inserted ACOM.V/ jack.(3) with one connected with the detected power or load, when the LCD is reading effective value of AC voltage measurement.

The current transformer and the ammeter do not show the same

Is the pointer of the ammeter clear? As you described, the flow ratio at one time should be 160:1, one 87A, and the current number is 0.54A
