How much current does this meter use when connected?

Right around .50 Ah ...not very much at all considering... I was worried about it drawing too much energy from my solar panel charging system, but its pretty negligible...you could always throw a toggle switch in there to save battery drain if your worried about it. Ive had no problems with it on my system for three years running now...just on here getting another one for a friend! I use one around the shop too for a portable voltmeter... the accuracy is right on the moneynwith my 89$ voltmeter at work...hope this helps, and I do recommend!

Well, current will depend on the draw of what you are connecting it to. you could put an inline resistor if needed. To control the voltage, you just turn the pot screw until the meter reads the voltage you want. you could do 12 or 18 volts with a turn of the screw driver. basically, this should do exactly what you want.

I have not had any problems with the meter, I am not sure what you are wanting to check the frequency of, but I use it on HVAC equipment and check frequency once in a while and it works for checking that.

Yes - As you repeatedly press the Meter button, the display cycles between (first for the connected device) Watts, Volts, Amps, Kwh, Elapsed Time, (then "Saved" quantities) Watts, Amps, Kwh, Elapsed Time. I'm not sure how the "Saved" quantities are calculated, so I ignore them.

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?

I measured the current of a 1 m. Section at .25 amp. So 5M. Should be 1.25 A.

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

U can zero it by touching the leads together...most meters do the same thing and depending where u r there is electricity all around as is shown on am oscilloscope.

I don't have a current meter on this but it would not work with my car or a 1amp power supply I have. It did work when connected to the 12v accessory plug (cigarette lighter) in my truck and boat.

I start to see some current at around 10 to 12 mph. It will depend on what voltage you need. I use it on a 24 volt system.

No.. But I understand and have measured the device used 20ma Sooooi. Add 20ma to your total when you need to know the whole usage I tested using a split USB cable and 2nd meter

Yes. If you put the meter in the circuit so current will flow through the meter.

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

dont know but its very little.i hooked mine up to my deep cycle battery overnight with my digital meter also hooked up and didnt drop any volts, not even a tenth of a volt.

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.

Well the best i can describe is...The meter needs 5 volt min to operate( small red and black on back of meter).Then your solar panels would go thru the Shunt or other 2 heaver wires. This meter has a internal Shunt(big heavy12 guage wire in a loop on back of meter)To measure currant up to 10 amps..Google the part # !

I don't know. I bought one and it worked for a while but kept loosing contact with the meter. After trying to reset several times and I gave. It was too late to return so I thought I would try again and bought another and it never could communicate with my meter. I'm stuck with two because I didn't return them soon enough.
