Can I measure true power with this meter? Also, can I measure current using the clamp AND voltage simultaneously using the test leads?

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

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

dont know... for future reference; get a resistor and measure voltage drop then calculate the current, ull blow a MM everytime trying to "direct measure" amps

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.

Just make shure that what ever your load can pull current wise the wire connecting the load too the shunt and shunt too power source or ground is capable of carrying the current one reason why I bought this meter is because if you have a floating ground it won't fry the meter like it will with one that has a fixed power source I fried one before bying this one do to a small amount of current going from my current source to my voltage supply if there is such an event with this one the reading will just be in acurate pretty bullet proof setup

The meter must have its own, separate power supply. I use a 12vdc transformer plugged into my inverter and it works great. I am able to monitor amps used by the inverter and other DC loads connected to my batteries as well as switch to see battery voltage. If you already have a separate power supply, you may have a bad meter.

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.

Yes, that will work. The meter reading will indicate the value of the power source voltage. Instant battery voltmeter if that's what you want.

You have to use a "Shut" to wire across for the current to be measured. The voltage will be measured when connected to your source. I don't remember the wiring sequence, but it was spelled out in the instructions. If I remember correctly Yellow goes to the shut, Red - Source Positive, Black - Source Negative. You would need to double check my memory for accuracy.

No, it cannot. In order to use the probes for a current measurement a shunt would be provided across the black and red terminals which would make the voltmeter useless. If your looking for a clamp-probe type meter that will also perform inline current measurements, look for a meter that has three probe terminals. The third terminal is used with a built-in shunt thus allowing current measurements using the supplied probes. Hope this helps.

Yes I suggest you try a side by side test to make sure.You can contact their website with questions.I believe they make a meter also.

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.

I just put an ohmmeter across the heavier gauge black and white leads of my meter (out of circuit and powered down) and I got a dead short. So yes, when powered off, the meter will pass current through the black and white leads.

Will this meter measure the DC current being drawn (like, from a battery)? YES!Just remember, it is a digital meter, so it is better suited to measure steady current. If the current fluctuates, the digital readout may look to be jumping all over the place.

I would not do that. I don't think it will give you a true reading of the battery condition. I ran a dedicated pair of wires from Positive & negative battery terminals to the meter. I installed a small toggle switch on the dash & broke the negative wire thru it so that the meter only draws current when the switch is on. otherwise it is always draining the battery. Hope this helps.

I doubt it very much. The meter requires power from the USB charge port. If you removed the power from the charge port to see if there is a discharge, the meter would not be powered. Your best option would be to modify a USB cable and connect in a milli-ammeter

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 can measure one circuit or the whole electrical service, You would just install the clamps on whatever circuit you want to monitor
