Will this measure current in excess of 2.0 amps... I need to measure at least 2.4 amps draw.

I do not know if it can measure 2.4A, but I have pushed it to 2.24A peak, charging my Galaxy Tab 3 via solar. USB ports were never meant to deliver that much anyway... The physical contacts are really taking a beating at this amperage. It actually sparks when unplugging.

The spec says no. Even if it can, I wouldn't trust the accuracy because it is out of range. CMRR of the current sensor might not be high enough at that high current.

The highest i have seen mine get is 2.1A. Its possible it can go higher but nothing i have has drawn more current then that.

No, max is supposed to be 2.4 amp per port. Until someone can measure the output, it should be 2.4 amps. The one I got couldn't do 2.4 amps like the description said, I suspect it was less than 1 amp per port.

You mean outputting 4.4 amps? Amps measures the flow in or out, volts simply refers to the charge of the battery/solar panels. Without knowing your setup, it's hard to say what's going on, but I would say no. It shouldn't be outputting 4.4 amps for no reason; mine certainly read "0.0" when no load was on.

You might be disappointed. Meter can measure down to 10 micro amps according to the manual.

To measure current there needs to be a load on the circuit. With no load there is no current. When a circuit is designed such as a SUB port it is made to handle a set max current output that means that a load put on it should not exceed that amount or the port will burn out. If you are building your own devices to power off a SUB port you should put a fuse in line rated at the maximum current output of that port.

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.

To measure current that high you would need a clamp ammeter or I would recommend the fluke i200 clamp that works with this meter. Remember that if it's AC then there is no polarity. I am assuming that your campground is supplying 120 or 220VAC

Unfortunately, it will not. It will give a lot of real time measurements and do a watt-hour summary for and time starting at the time it is plugged in but this probably won't help you. You will get real time current usage if you want to watch your amp draw current as you play with volume and speaker loads.Hope this helps.

Hi Shane,as you know these meters are very sensible. Off 2 Amps looks like mech. damage. When you move the meter the needle should move free in either direction. There is a black plastic screw below the gage. Here you may adjust the needle, but not sure whether such a large misalingement of 2 Amps. Does the Ampmeter works anyway????Good luck my friend

All I have is a hand held meter with a needle. It displays 2.1 amps on start up. I am using an Active Air variable speed controller with mine. http://www.amazon.com/gp/product/B003URBQ1M/ref=wms_ohs_product?ie=UTF8&psc=1

It measures to .01amps. I use it for that very reason and suceesfully found a short on a 12v gmc van.

You can but it will activate the circuit because it's probe voltage is too high, so it's really not meant to. If you want to do in circuit measurements get a dedicated ESR meter. The ESR function on this device isn't really very accurate anyway, it's mainly useful for transistor testing and LCR.

The power supply that comes with it is rated at 2.5 amps, so I would say that if the total draw is less then 2.5 amps then you would be good. The max you are supposed to draw per port is 0.5 amps, so times 4 would be 2.0 amps. It'll probably work even if all four on at the same time.

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.

Only by using a clamp on amp meter attachment. As supplied it only does amp readings by inserting into the circuit. Fluke offers several clamp on ac, ac/dc, and varied current level "probes" as they describe them.

Measured Draw at 13.2volts is 2.4 Amps, just purchased the product in December and connected to a Voltage/ Amp draw meter and there is no initial "strong" draw, just constant draw at 2.4 amps, this unit is running off a battery storage unit, charge by solar panels, for my fish pond in my Aquaponics System

I haven't done that yet. I'm not putting more that two amps through mine. but I would imagine that you would burn it up. I seriously doubt it is going to read over 9.99 amps. If you are determined to try this, before you try to put 30 amps through it, I would add a shunt in the circuit ahead of the amp meter.
