how to measure ac circuits
1504584
If you are trying for voltage you can use this tester. If you looking for anperage you need a multimeter. I need a little more information to properly answer your question. But if you need volts in an outlet you need to set meter to ac current and plug one probe into hot terminal on outlet and other probe to neutral or ground.

hi tom thanks very much for your answer i was having trouble trying to find a fault in a lighting circuit but i found the problem and it is ok now thanks vince

HI Visa, need a bit more info,..this instrument can tell you if you have power, if your neutral is connected and if you have a short circuit. If you need to know how many circuits there are in a space, count the circuit brakers. If you need to know how many receptacles are on a circuit, shut off a breaker and see what is live or not and you'll be able to quantify them. Have fun, Tom

I've used the MS2108 to measure 12vdc parasitic current on my RV. Not sure of the overall accuracy (don't have another meter to compare with), but it did seem to be reasonably stable down to 100ma (only used the clamp-on function). I didn't make any measurements less than 100ma, so I can't comment on measurements less than this.

Yes you can measuretrue power but you cant measure current and volts at the same time

AC current only. Also, it's only an averaging meter. You need a true RMS meter with a clamp capable of measuring DC.

Measure it with a voltmeter. Or use a battery tester. You can get a multimeter (measures volts, amps and ohms) for as little as $15. Then have someone show you how to use it. Its not hard and it's fun. Many other uses such as checking continuity, troubleshooting your car, checking electrical sockets, etc.

I did not try this into Amperes yetBut I am SURE this multi meter will measure even a .001 ac or dc Volt

I used it as a DC test not AC. I tested it with an Oscope and found it peaked the circuit so it would work for what I bought it for. I was afraid of burning up the iunits next to what I was testing so I have very little time with it.

I just held the old plug in front of a ruler and estimated. You could also borrow or buy a caliper. Harbor freight had one for $10. They are handy for lots of measurements.

No idea. I never had a problem on a 15 amp circuit. Who goes around measuring current on whatever devices they plug in? Kind of a pain, what?

It will read up to 100amp if current continuious, I have it hooked up to an ACC unit to monitor usage

Yes, it measures AC voltage. I am not sure what the second part of your question means. AC and DC are totally different beasts. If you have AC you can't probe for DC, and if you have DC you can't probe for AC-- this is true regardless of your meter, unless there are meters that can automatically detect that your current is one or the other. In the US, your device will receive AC and will either supply AC or DC or both to different parts of your circuit. Part of most consumer electronics is a power supply that converts AC from your wall outlet to DC. To convert DC to AC you could use an alternator. I hope some of this information is what you are after! Yes, it measures AC voltage. I am not sure what the second part of your question means. AC and DC are totally different beasts.

Sure, but it will only measure the AC side of things. If you want to measure the entire RV, you'll need to attach it to the main feed wires going into the distribution panel where it will see power from any source (generator, shore, inverter). To measure power going to/from your battery bank, use meters designed for DC (with an appropriately sized shunt) and place them for either incoming (charger, solar panels, etc.) or outgoing (to the inverter or the DC breakout panel) power. For simple DC voltage measurement in my RV, I use one of these http://www.amazon.com/VoltMinder-Digital-Volt-Meter-Batteries/dp/B001IQ1XW4

It will measure to .001a/AC-DC but will not calculate amp hours. Milli amps yes.

Frankly I dont know as I never use it, And my manual doesnt really go into great detail?, But there is a line that says : "Plug the Red Terminal into the Output to block the DC when you want to test AC Only!. 'Outerwise its a Nice tester and in my opionion its a real steal at this price as i am very well satisfied with mine but again to each his own!. Hope this helps: BEST WISHES!.....

I believe it can measure 120, 240 or three phase power. It comes with TWO current probes.If you only attach ONE and restart I believe it will measure 120 volt single phase. However, if that is all you want to do , buy a Watt Wizard for much less money.

It is 12Volt AC 3 phase, hence the 3 wires. 12V will be measured between any 2 wires

It will measure current well under 5A DC. I've been told clamp on meters aren't very accurate and I think this is compounded at lower currents when the coil is influenced by other stray fields. When I went outside and did a little testing with my trickle charger (and leadtype multimeter in series) I found that it's quite accurate (within 10%) down to 0.5A but when I got to the 0.05A it was out by up to 75%. I think your results will vary depending on environment.
