What's the maximum current/power that this will safely measure?

Box says max is 2.00A. I have measured 2.5A for a brief period without any noticeable damage.

I tried to use it to measure the current on a Dell Venue 11 Pro, using the OEM charger, which should put out more than 2A. The display read 0.00 for a few seconds, then there was a spark inside the unit. After that it reads 0.00 for any load. The voltage side of it still works, but the Amp circuitry is fried. You may get lucky like the previous answerer, but if you want to regularly check tablet charging, you might want to look at another device. Other than that, great product and definitely works as advertised!

Yes, this is a voltmeter, so it will read whatever the voltage is at the time, it doesn't have any memory capability.

I've been using it side by side with a digital usage meter provided by my utility company (SMUD) and it is always within 30 Watts (shows 30W less). Not a scientific test though :).

Actually Volt-Amps and Watts are both Power measurements. However, due to the inevitable presence of capacitance and inductance in the UPS circuitry as well as the load connected to it, the UPS is rated at a reasonable maximum output of 900W.

Hold it to where it does not go off and move it towards a power cord or a fluorescent light. It should go off the closer to the power it gets. It does not tell you if it is measuring EMF or RF energy.

Take a digital Volt meter and it will tell you if it is positive of negative.Don

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

use amp probe, see how much current is being used, and check valve to see if any debris is inside

I don't know. How would I find out without some sort of voltmeter? (Is this info possibly on the website specs?)

Answer here...Yes it will let you know how much wattage each legg is pulling when under load,and wired into your circuit panel.In your case I would think a kill O watt meter might be better,it will let you know how much power the solar panels are producing.Plug inverter into kill o watt meter and from there run out of kill o watt meter to your circuit panel.The MB75 lets you read wattage being used off of each buss in your panel so you can even out your wattage from buss A and buss B,in return making your solar panels produce and last much longer,in my case it makes my portable generator run,and last much longer.Hope this helps let me know how it turns out.

Do not know.Cannot seem to find numbers for max and min.Just keep a watch on voltage and if it goes way up or down start asking questions.

If available use a powermeter to get a baseline since it is the most vakide and reliable but it's not required

I'm not sure what the actual power usage is, but I'm sure it's minimal. As for your second question, any object or device subjected to an unstable climate with temperature swings as wide as 38-100 will be adversely affected. Why would you want to subject a finely calibrated electronic instrument such as this to that sort of abuse?

Less than my clamp-on ammeter would respond to. I'd have to disassemble the circuit and put a series meter in the circuit to find it for certain. If you call the manufacturer they probably could tell you. They do have a web site. Just a guess but I would think it wouldn't be more than about 20 mA at 120VAC.

Maybe too much current. measure it and compare it to diode specks check to make sure the diode isn't shorted.

Idk. I think you might be asking to much of a voltage detector. Shouldn't rely on this for safety or for electronic motherboard applications. Best bet would be to get a multimeter to suit your application. Fluke always makes a great meter. Could go cheap but you get what you pay for

There is no multimeter that isn't sensitive enough to determine this. However it is usually 24VAC, at least in the US but custom bundled transformer and bell sets may differ.
