How acurate is the dc amp reading? I need to accuratly measure 10-50 milliamps

I've used the MS2108 to measure 12vdc parasitic current on my RV. Not sure of the overall accuracy (don't have another meter to compare with), but it did seem to be reasonably stable down to 100ma (only used the clamp-on function). I didn't make any measurements less than 100ma, so I can't comment on measurements less than this.

Couldn't answer as it does not register. Do not recommend this. Instructions are in Chinese with no translation

I never checked that low. I bought mine for checking the batteries& charger for my golf cart(36vdc). Also for the fountain pumps in our ponds(120/240vac). Works well for my applications. Maybe you should try an ohmmeter , with the 10amp series hook up.

Sorry can't remember. The seller should have such info. Should be adequate for most amps or ears.

It Doesn't work, I wanted to do the same thing. I purchased 3 of these from different sellers, but none would work measuring amps.

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

If your incoming feed is wired correctly, one clamp goes around black, the other around red. You can confirm with an AC voltmeter. Between black and red you should read 220-240V.

It says its operating voltage is DC12V 60mA which, using ohms law, would mean they would draw 0.72w. --&gt; 12 x 0.06 = 0.72

The device will read load current. However a 100A/200A DC shunt may not be what you need since changing currents are considerably much lower. Hence you will need to change the 100A/200A shunt to a lower scale/current rating to obtain a more accurate reading. There are shunts for this device on Amazon.

It says 19vdc (Volts DC) at 2.1 amps. Thanks for asking, because mine was very warm so I moved the power supply to a place where I could get more air to cool off. ;)

Yes, it does measure milliamps. All multimeters test milliamps, in fact that is actually all they ever test. They read voltage by running the test voltage through different resistors, depending on the range setting. By measuring the current through a resistor of known value, the voltage can be determined by a simple calculation. I've found it to be accurate for voltage, therefore it would be accurate for reading milliamps. RichieD Inexperienced technicians often burn out ammeters by running too much current through them, so be sure you know what you are doing before using it as an ammeter.

Sir, according to the user manual, you can test up to 10 amps (DC only) however, for every 15 seconds of testing, you must wait 15 minutes between tests in order to allow the meter to recover from that level of current. You can download the manual here, just click on the "Download Manual / Software link" Hope this helps. http://innova.com/en-US/Product/Detail/3320

My power supply cord says input = 120 V , AC 60 Hz, output = 6 V, DC 500 mA

Use a multi meter to measure the voltage at the output terminal while you are adjusting the voltage. The input voltage just need to in the range of the specifications.

Yeah, but it might take a little longer than a higher amped DC adapter. And it will hear up and smell like burning plastic. I fear this is a fire hazard and threw one away cause I just didn't trust it.

Hm. First, what does your laptop say for dc voltage in and amps? Second, measure the hole where this plugs into and see how big it is

I have not personally measured this high of current on AC or DC since I have owned this meter. However FLUKE claims it is possible to measure 400 Amperes AC or DC, also up to 600 Volts AC or DC.

The instruction manual specifies 0.1 mV resolution on the 400 mV range for both AC and DC millivolts. I've never used it at that low of a voltage level, though.
