Setup normal w/shunt that came w/unit. Volt OK, Amp reads about 200% of what it should -two other A meters as check. Is there adj info?

I have not put mine into service yet. I would suspect that it's the wrong shunt, I'd be surprised if the adjustment (if there is one) would have that much range. I'll try to check mine out and let you know what I find.

This link on YouTube can help with wiring and setup of this type of volt meter installing, i use that video to install on my car to see the volt from my HHO Generator.

Use a multi meter to measure the voltage at the output terminal while you are adjusting the voltage. The input voltage just need to in the range of the specifications.

Yes, I had the same problem. The two smaller wires are the supply voltage for the meter itself. Red is positive, black is negative. I used 5 Volts DC to power mine. The bigger wires are red, blue and black. Red is the voltage sense, blue and black are for the current sense. Black should be connected directly to ground. The blue then becomes the ground for whatever device you are sensing the current on. So, the ground side of the load goes into the blue wire (then through a shunt resistor) and then out of the black wire to ground. Hope this helps! :)

I suggest reviewing the manual and contacting the manufacturer. Are you actually drawing any load? You have to have a load connected to see any amp draw. Thanks.

When you are reading DC amperage, you are reading the current draw between the source and the piece of equipment. the amperage will vary because of many factors. it is normal.

My unit came through dual voltage and I can't see any difference when I'm welding except for max output being lower. I love my unit. Paul M

the meter does not have an internal shunt. you must buy a standard shunt 0.005 ohm and use 100 ohm pot to calibrate the meter to read 20Amp.

I have 2 units and have to issues with neither of them...I use it for basic AC and DC power reading takes. I do get some insignificant reading when power on but when connecting to the power source for measurement works well and power reading are correct.I hope this helps....

I don't know of an online diagram for it. I just checked all of my assumptions on a multimeter, rather than trusting documentation. If you have specific questions, I will be happy to help.

Put a good multimeter on the out put leads and spin it. you will read DC volts with NO ac COMPONENT. ww

That doesn't make any sense? And it could be impedence not the meter. Get a wiggy to test out high impedence circuits. Make sure you are selecting the correct voltage type on the wheel! There are two types per selection

How did you try to measure 24 volts? If you used 2 twelve volt batteries in series make sure they were connected one + lead to the other - lead. Or try to measure 3 nine volt batteries snapped together. You should get 27 volts. I think there is a calibration pot on the back of the meter. It is very small and you will need a jewelers screwdriver to adjust it. Make sure the red lead goes to the + termingal of the battery. Try again and let me know. You could have a bad batch of meters. Mine worked very will on my power supply that goes up to 27 volts. One last thing...are the 24 volt batteries you are measuring good batteries? The meter might be telling you that they are not. Hope this was useful. Also be aware that all meters have a percentage of error. Some are + - .1% + - .01%. No matter how expensive the meter it will have error tho very small. The smaller the error, the larger the price. These cheap but beautiful meters are good enough for battery monitoring. I wouldnt use them to build a computer power supply.

dont know... for future reference; get a resistor and measure voltage drop then calculate the current, ull blow a MM everytime trying to "direct measure" amps

Check with your electrical inspector. That being said I used 2 of the available spaces and mounted a 100 amp main. Still have 2 extra spaces and doubt I'll ever come close to using more than 100 amp. No main was required by local codes but I like to be able to kill all power to box. Hope this helped.

The shunt is needed to carry the current u are using... the meter mesures what is going thru the shunt ..some meters have a internal shunt (only 10 amps)or soothis meter is 100 amps. any more ? Drauschmachin@hotmail.com

not sure why 2.4 amps is getting discussed..it says right on the package "under half an amp draw" and my meter says it takes about 0.3 far reach from 2.4

Yes, I am busy using it to indicate the charge coming from a bank of solar panels. I am going up to a max of 42A (using the 200A shunt) - it does not seem to give a reading at low currents e.g. 1A but once it goes over this it is pretty accurate. I am using the battery that I am charging as the supply and it works fine.
