Is it useful as a meter? If you are using the CV supply, will it show the current draw (amps)?

This Power Supply can be used as a meter but is not very accurate and is not advised because it has a limit of 30 volts. The display shows amps and volts together.

NO. You should know you need an oscilloscope, this is a current measuring device and if you don't know the difference, you had best stay out of the circuit panel !

100 amps is the most I've ever tested with this device but that is accurate enough for our line of work. If you want a device that is extremely accurate this may not be the tester for you.. It seems to be more geared to general testing..

You are showing a need of 150 amps of measuring range. The unit range shown is 50 amp. I think Amazon offers others that may be good for the 150 amp range that can be powered from a 12 volt battery. They will show the charge and discharge if wired in correctly. The current shunts are made to handle a wide range of current for measurement as long as you select it large enough for the application.

hi this meter does measure dcamps it got me out of strife on a truckit doesn't say in the instructions it measures dc amps but itm does try it use the jaws it works but the dc amps simble doesn't show when doing this test but it works

Thanks...i used a small 5v USB charger and powered it from my switched AC source. I just don't see where anyone mentions you need an independent supply of 4 to 30 V to run the meter. I was planning to use the power supply I was building into a case with the meter to show voltage and current being used by the connected devices.

It is AC only for current, and only up to 100 amps like it says in the specs. Wire that is big enough to handle 240 amps won't fit in the jaws anyway. I have carried this meter for 14 years as an electrician, and it does 99 percent of what you would need. Very fast read, too, which is nice.I also have this one that does do DC current:http://www.amazon.com/Milwaukee-2236-20-Clamp-Meter-Refridgeration/dp/B002EL4LAI/ref=sr_1_1?ie=UTF8&qid;=1429118708&sr=8-1&keywords;=2236-20NST.

I.m not sure why you specifically mention relays on vehicle air conditioners, as if that would take a special meter. However, this little inexpensive meter does have the ability to measure volts, both AC and DC, ohms, amps, check capacitors, diodes, do a continuity check, and resistance checks. So, depending what you are wanting to check, I think it would serve the purpose just as well as a more expensive one, if you are worried about cost. I really don't know what else you would need for checking a relay, whether on a vehicle air conditioner or any other piece of equipment. Most of the time you either want to know !. is it getting power, 2.are the points open or closed, 3. is the power getting across the contacts, or 4. is the relay coil burned out or not. So yes, I think this would do what you want it to do, and for a good price. For home use, or a DIYer, this is a good little tool.

I use device to monitor output voltage and consumption on a 12 v battery. I connected it as shown in photo "Wiring Diagram 3" in product announcement photos. Shunt must be in series w/negative side of the load; the 2 other cables to the + & -terminals of the same battery. No adjustment necessary.

I don't have a current meter on this but it would not work with my car or a 1amp power supply I have. It did work when connected to the 12v accessory plug (cigarette lighter) in my truck and boat.

Update on my previous answer since I now have a new meter to measure all DC current draw on my vessel. With all 5 lights on, they draw 1.1 amps of DC power...That is a very low current draw!! I am adding 2 more this winter.

I don't use this meter for ac work. I checked the meter and the info I got with the meter ( which is not much). But it will not do what you want . sorry not much help. Bill

After checking the manual I think the answer is no. There is wording in the manual:"To measure current, you must break the circuit under test, then place the Meter in series with the circuit." There is a clamp on style attachment. Of course that would only measure large Current Flows. Other replies seem to say there MAY be a special probe for small current values.

No, but check the name plate, that will tell you the voltage and current draw, amps.

I don't think so. Even if you only use basic ones like voltage, amperage, and resistance, it's nice to have other functions available and it is great to have the accuracy this meter provides. It is very well-made.

I like to offer a speculation: for the meter to do what you hope it will do, would require a more complex sensor and circuitry. If B&D; went through the trouble of providing that they have no incentive to keep their efforts a secret. There is no reference to this in the manual.

Should have a small data info sheet in the bottom of the box it comes in. The connector that has two wires(I used a nine volt battery with a switch), red & black are for display power. The other wires are for voltage sense & amperage (milli-volt) from shunt. Yes, a shunt is required. This is a good meter, just not enough information to support it's installation & calibration. Two adjustments (apex) on the P.C. board are for the calibration of the volt meter & amperage read-outs.
