Can the unit tolerate a source and load reversal? I'm wondering if the meter would be damaged if the source voltage dropped and became the load.

The unit is not damaged when reversing current, but the meter does not display the reversed current. I have used this when charging and discharging my LiPo's. With my wiring set up while cycling I can read total discharge, but not re-charge. The display isn't blank under those circumstances, it just doesn't change.

I have no idea and I'm not going to try.In general the meter seems pretty robust at measuring large, variable loads in the direction it was designed to measure. My application was an electric bike with a typical voltage above 50vDC and loads all the way up to 1.5kw.

sure can,after all it's a fluke.Be sure to set the meter on "A" and set on direct current/Be sure to set on the highest setting as if you set it to low you will blow the internal fuse.Good luck pal.

No you can measure voltage and current and it is a true rms meter but you cant measure both at the same time.

NO!!! Not a good thing, it would damage your machine. You need either a converter or and electrician, neither are cheap. Suggest you return it if you have the option and purchase a 120volt unit, or sell it and do the same.

the meter will measure only a point in time and at that measurement everything may be fine. Problem is an hour later the voltage may have degraded due to all the other campers loading down the system. You could leave the meter connected continuously but then you would have to be looking at it all the time for a voltage drop - some so fast you may miss. You could purchase a line voltage monitor with an adjustable trip point / alarm. So if the normal voltage is 120 volts and your alarm trip point is say 110 then you would get an auidable alarm so you could shut down any devices that could be damaged by low voltage. This type of monitor would be a better investment than the meter since it monitors the line voltage 24X7. Something like this would be a better idea in my opinion - Technology Research AECM20020 Digital Monitor - I did a quick amazon search on Line voltage Monitor Alarm

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

Not sure off top of my head. Normally I use a voltmeter to check these things. Properly designed circuits will have a blocking diode to prevent polarity reversal issues. Those that don't, may have smoke issues!

Sorry I never changed fuses in this meter. But I' will look & if I find out I'll let you know. Bill

my understanding is that the source side must be the most positive than the load side.also the measured current is only on the negative side (black wires).even with zero current the meter will still read zero provided you have at least 4v between the red and black load lines

The meter is not symetrical, and one side must "face" the source of power, as outlined in the directions. Double check you have that right. From your description, I don't know how you have the panels wired. I would suggest you test only one panel at a time, and see if it produces 80% of it's rated power output when in direct sunlight and when the system is under a load. You could have a defective panel, a short, etc. (I'm assuming that you have already tested the meter using just the battery and a load and know it's okay)

It is a transformer, yes, and the mode of failure would most likely not result in any damage to the appliance. However should there be a large spike in the input voltage such damage must be considered as a possibility.

You don't. On AC, the meter ignores any DC component, so any DC offset is ignored.

The unit failed during actual use. Sent it back to the supplier and got my money back. So I cannot answer your question.

I found the voltage approximate with 0.25 to 0.5V. Generally the measured voltage would depend on the load. A high current load will likely drop the measured voltage.

I have been able to operate my meter at 60v and below with no problems. I have 3 meters and they all work well.

Sorry the current transformer that is supplied can only read one magnetic field or current load at a time. I am monitoring a generator with two 110 volt hotlines, so I purchased two of these meters, each meter independently reading each line, and this is pretty much the way it's done. To be honest with you I have no idea what would happen if you ran to hot leads throw the current transformer, I know this much it would not read correctly. Pick up another meter, you not only be able to read the current of each line but you'll also be able to read the voltage of each line independently this is the way to go.

i believe the answer is yes but to be on the safe side you might think about a voltage down-converter; i just examined the tool and the owners manual but nowhere can i find allowed input voltage; nor can i find their company website to answer your question; i would expect one of two things happening however: 1. the electronics might blow on plug-in - or - 2. you MIGHT be able to operate the device to half-scale; i've been finding out the hard way: cheapest is not always best (you get what you pay for)
