Does this unit measure amperage on unopened circuits?

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.

No. And I know of no way a DMM could. Only clamp type meters do that and as far as I know their use is limited to AC.

Not with the included probes, you'd need an amp clamp to do that. Their clamp style probe has low resolution with currents under 1 amp but I've heard their thread-style amp probe is more accurate with those situations.

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.

It gives a running digital reading of amperage AC current, not DC. It has no capture capability for highest amperage event, your eyeballs have to do that. It does give quick readings however on a continuous basis if amps are selected, or watts, or volts or cycles per second or kwh.

No - it measures wire length (in feet or meters only) according to the gauge of the wire - copper or aluminumAccuracy is pretty good

You might be disappointed. Meter can measure down to 10 micro amps according to the manual.

i don't think that will work as you would be measuring micro voltage , you may need a galvanometer

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).

It measures actual voltage and current in milliamps. It updates about the times a second. It is neat to figure out what chargers and cables work best for each device. Worth it. The other two brands available on amazon look like crap. I couldn't find this in the US. Had to buy from Japan.

It will read DC Amps but accurately, I was reading a 3Amp load. I would suggest with all cheap meters to replace the probes and spend a little money $15/20 on a decent set of probes. Then it will read DC amps accurately once I replaced the probes.

Yes, this is a voltmeter, so it will read whatever the voltage is at the time, it doesn't have any memory capability.

I don't have a current clamp for my multimeter to measure it, nor the schematics of the device to assess whether or not it it would draw any current. If I lost any electrons then I would be positive!

Yes it will. It will tell y the wattage, volt, amps that ar being used in the outlet it's plugged in.

It depends on the amperage, however the one I purchased had a defect and did not work at all.

Measures AC/DC Voltage up to 1000V, AC/DC current, resistance, frequency, capacitance, temperature, and duty cycle

Yes, I am busy using it to indicate the charge coming from a bank of solar panels. I am going up to a max of 42A (using the 200A shunt) - it does not seem to give a reading at low currents e.g. 1A but once it goes over this it is pretty accurate. I am using the battery that I am charging as the supply and it works fine.

NO. You should know you need an oscilloscope, this is a current measuring device and if you don't know the difference, you had best stay out of the circuit panel !

It will read up to 100amp if current continuious, I have it hooked up to an ACC unit to monitor usage

Because the current is constant anywhere within the "loop", you can measure amps anywhere in the line. However, voltage "drops" across various components throughout this loop. If you want to measure the performance of your battery (common), place this item close to the battery between the charging source and the battery to be most accurate.
