DD862 type single-phase inductance AC active energy meters are used to measure active energy loss with frequency 50Hz or 60Hz。 features: new design, resonable construction, high overload, low power consumption, long life , high stablity. the meter is very popular by customers.


Type and meaning
Type and specification
Main technical parameters

1、Meters conform to GB/T 15283 -1994 and IEC 521-1988 standards.
2、Meters can be made into types: direct wiring and CT/PT wiring.
3、 Can be made into special meters according customer's requirements (different frequency, voltage,current specifications etc.).
4、 Start-up: under the condition of the referenced voltage, reference frequency and cosΦ=1, and the load circuit doesn't exceed the 0.5% of the basic circuit, the ammeter's rotor can be started up and constant turning.
5、 Potential action: the ammeter's rotor turns without exceeding one cycle when its line has no electric current and the voltage is 80%~110%of the reference value.
6、Power consumption:active power consumption of voltage circuit less than 2W(under reference conditions).
7、Dielectric properties:1.2/50µs wave,peak value:6kV, no damage permitted under 10 times test. meter can withstand 2kV(circuit to earth, under 45~65Hz,1 minute)。


Outline and installation dimensions


Q: i the wiring going to the fue box bad or is the ecu bad?
Put a fuse that is correctly rated for that slot. Turn the ignition on (engine off) and see if the fuse pops. Right now you may have a short in that system. You need to recreate the situation that popped the fuse in the first place. The only way for wiring to go bad is to draw to many amps through the wires that will in turn, melt the wires. The fuse box is there to protect the vital components of the car. If the mass air flow sensor is not working, the car will not stay running. It will start, but not stay running.
Q: I looked inside the tv and there in no burn marks or components. What would cause the fuse to blow out. Can anyone help me?
Something inside of the set is shorted out. This can happen even though nothing appears burnt. My guess is that it is something in the power supply.
Q: I have an old 1998 dodge stratus and it keeps blowing the ignition fuel starter fuse(20A). I replace it 4 times and they failed. Can someone tell me what's going on and I can get over this?
i'm guessing that you are talking about the fuse for the fuel pump two things can cause the fuse to blow. bad fuel pump, or a short in the wiring.
Q: I turned the key once for the electrical components and it worked for a split second then it went dead. Then I tried to jump start it and nothing happened, no clicking or anything. just dead. Then, when I unhooked the jumper cables, there were sparks from the jumper cables which would indicate that the battery isn't dead.
If the jumper cables were still hooked up to the other vehicle, then that is why you got sparks between the two cables. How long did you leave the cables hooked up to your vehicle while the other one was still running? Hook the cables up to a good battery and then to the bad battery. Let it charge for a few minutes and go back and give it another try. If you still don't get anything, then you may have a cable loose somewhere, like between your battery and starter. Could be a solenoid or a relay also.
Q: i tried hooking up the positive to the fuse buss but it shorted out a couple fuses i may have gotten the wires confused
The positive wire goes to an accessory wire (or a blank accessory terminal in your fuse block if so equiped). The other wire goes to ground. It has to be ground to the metal of the car. All of the electrical components in your car are grounded to the car. The electricity comes from the battery through the wires to the components, goes through the components then returns to the battery using the metal of the car (aka the chassis). Also, add a fuse to the wire if there isn't one already. A live wire in the car without a fuse is very dangerous.
Q: During the battle of Gettysburg, the gunfire was so intense that several bullets collided in mid-air and fused together. Assume a 4.91 g Union musket ball was moving to the right at a speed of 248 m/s, 20.3° above the horizontal, and that a 2.96 g Confederate ball was moving to the left at a speed of 282 m/s, 16.0° above the horizontal. Immediately after they fuse together, what is their velocity?
For this problem, you'll have to use conservation of momentum in both x and y direction. For x direction - m1v1 (x) +m2v2(x) (m1+m2) V(x) 4.91*248*cos(20.3) -2.96*282*cos(16) (4.91+2.96)*V(x) solve for V(x) here. V(x) would be the x component of the vector (as asked in the question format). Similarly conserve momentum in y direction, and solve the problem.
Q: I have found the source of the drawfuse is connected to the lighter/dome light. That's all it says on the small fuse panel anyway so as far as starting to change the bad wire or component goes am I really just looking at the lighter and dome lightor are there usually other items connected to this fuse as well?Just looking for guidance - age old tips to make my troubleshooting / wire replacing task less daunting.
that should be all that's on it,but here's what i usually do ,pull the fuse and start checking to see what all wont work on it,the put it back in,and see what all does,this helps narrow it down a little,and it also gives you a direct shot at what the problem may be on it,make sure some one hasn't used the hot wire on the back of the lighter to wire something else to it,often people do this on a RV,i do a lot of work on these,i like working on them because there big enough that you don't have to squeeze in to places,and the wiring is usually strait forward on these,but that method right there has helped me a lot in the past,maybe it will help you also,good luck with it,hope this helps.
Q: I have no idea what this component is or where to get one. It's from a sleep comfort bed pump and I need a replacement part. Here's a picture of it and the pump label.
I think it is a 1.6 amp fuse. Judging by the black streaks on the board, however, something else went wrong, and blew the fuse with a serious overcurrent. That is to say, just swapping the fuse is likely not to fix the unit; it will probably just blow again. Whatever blew the fuse is probably still wrong, unless you know what that was and have fixed it. You can probably just solder in a fuseholder in its place if you cannot find an exact replacement. One with wires at each end will probably be simplest. I suggest you ask the manufacturer how much for a new board. I am guessing that this is for a vinyl air bed. If so, if the mfgr wants too much for a new board, Coleman makes a very good inflator, included with their airbeds, but I think available separately for $15 or so, and you could probably kluge it into place, though you might need to remote the switch.
Q: I Have an 01 mitsubishi galant GTZ and the right passenger side parking lights, (running lights) dont work. The dash lights also dont turn on. Now the fuse was blown and i replaced once i turned the lights on it would blow again. I asked around and i was told it was a short. How to fixx? Please help.
Your dash light more likely works off the same fuse for the parking lights. maybe is not just the right side but the parking lights (running lights) over all? may be the car was involved in a accident on the right side and the wires may be touching some sharp metal or maybe on light bulb was replaced on the right side and it was installed wrongly (180* off?) I hope this info is helpful!
Q: 1. Protection against disease2. Communication between cells, tissues, and organs3. Oxygen transport4. Carbon Dioxide transport5. Buffer against pH changes6. Nutrient supply7. Tissue repair8. Transport of hormones, lipids, and fat soluble vitamins Hurry!!!!!!!!!!!!!!!!!!!!!11
1: Could be White Blood Cells and other immuno cells 2: Hormones 3: Hemoglobin located on red blood cells 4: Carbonic An hydrase (which fuses CO2 molecules into a bicarbonate for transfer in the blood) as well as carbamino hemoglobin located with red blood cells and some plasma transports small amounts of diffused CO2 5: Red blood cells hemoglobin and bicarbonate are 2 major blood pH buffers 6: Don't know what you mean cause glucose, amino acids and fatty acids/ other monomers float freely for the most part in the blood (plasma if you want the correct portion of blood) 7: If by tissue you mean clotting then platelets and clotting proteins like fibrin/fibrinogen 8: Carrier proteins carry those things. or they float freely anything thats a protein or cell is part of the solid component anything not manufactured by the body is plasma portion, e.g. glucose, amino acids and such been awhile since I did circulation so I hope thats pretty accurate
