What is the smallest ac and dc current you can measure? Is the dc measurement small enough to hunt down parasitic battery drains in a 12v car?

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

Update on my previous answer since I now have a new meter to measure all DC current draw on my vessel. With all 5 lights on, they draw 1.1 amps of DC power...That is a very low current draw!! I am adding 2 more this winter.

hi this meter does measure dcamps it got me out of strife on a truckit doesn't say in the instructions it measures dc amps but itm does try it use the jaws it works but the dc amps simble doesn't show when doing this test but it works

The Klein CL2000 is fine for 12A to 25A DC. I've used it at both lower and higher direct current levels than those.

1.Voltage is the amount of power something can output. Many battery chargers will measure the voltage in a battery to determine if a it is good or bad. 2.Maybe it's possable because when I bought this item, I didn't think about it. 3.Anyway It' the best item for car (power,price,easy to use, case,).Before I used similar item, but it was not strong so I got it again.4.This item will be helpful for car and home clean. = Car Power DC to AC Inverter AC/DC Adapter Converter Charger 110-240V AC to 12V DC / Universal AC-DC Power Socket Adapter Converter - Use Car Chargers in 110V AC Wall Outlets 5.

no I measured the amps. at between 130 - 160 ma. thats at 12v-13.6vdc hop it helps

In my car I'm running a shunt between the alternator and the negative terminal to read the amps, the power was tapped from a cigarette lighter wire. I believe running the tiny power wires to the shunt would fry them when cranking.

AC current only. Also, it's only an averaging meter. You need a true RMS meter with a clamp capable of measuring DC.

There is a setting for 12volts but I wouldn't use this tester for a car battery. I would would either use a load tester or take it to an auto parts store or garage and have them test it.

I remember researching this before. The manufacturer won't say exactly. Read the forums on nPower. I might be able to figure it out with my multimeter when I get home. I thought theoretically, you could figure it out with an equation. it was enough to start my v6 2.1L engine. The inverter to ac isn't much. If my calc is right, 400W at 120V is only 3.3A on AC, but you can't expect much from a 12v battery. I thought dc was supposed to be infiinite, but I suppose you're looking for cranking amps. Overall, I was very pleased with how the nPower performed. I went a couple of months before finally diagnosing my car battery. The nPower got a fairly large engine through a cold Wisconsin winter with a bad cell in a relatively small car battery.

This measures AC power usage in watts, kilowatts and watt hours. To monitor your batteries you probably want something like a Zantrex Link Lite or Link Pro which shows battery voltage, Amp Hours used and can be programmed for the capacity of your battery bank to show your particular systems- "Percent of charge used" and hours till empty as well as alarm outputs for when you your batteries are running low (which can trigger a generator to start up or just an audible alarm).

If battery is at least 5 volts and gauge does not respond when connected then gauge is bad. My recollection is, there is nothing to adjust or set up on these. Just the two wires.Max 30V so don't connect to wall outlet! (duh, these are DC anyway).I'd test by finger-pressing the stripped ends of the leads directly on the tips of the 9V battery.A regular 12V car battery would also have contacts available for testing, in most cars.

As previous answer said it's about currents. Alternating Current (AC) produces a magnetic field that this device detects. Vehicles only produce alternating current in the alternator BUT AC is immediately converted to Direct Current (DC). The only way to test for current in a vehicle is to use a standard multimeter.

I just ordered my device, so this "answer" is from principles only. To measure DC current one puts a low ohm resistor IN LINE (in series) with the current carrying wire. Then one measures the voltage drop across that resistor and computes the current by Ohm's law (actually the device does this for you). The resistor can get hot, so it must be air cooled (hence external). It appears that the shunt is included (see picture).

Yes, I use mine for that on occasion. Be careful when the car is running, the alternator could pop the fuse or drain the 9V battery in the multimeter rather fast. There's not a whole lot you can learn about the battery with a multimeter, but they are quite useful for testing devices in cars/trucks. e.g. you can test your coil packs using the Ohm-Meter (resistance) functionality.

It is 12 volts DC, but the amperage is different, probably the max you can use in a car. Anytime there is heat involved, your amperage will be high. I'll be able to check in a few days.

Yes, at 13.8 volts DC when your car is running. With engine off battery voltage is lower and so less power.
