Fluke 325 Clamp Multimeter AC-DC TRMS

Q: 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?

You need to look at both resolution (0.01A on 40A setting) and accuracy. For example, if you try to measure a 50 mA current... ±(%2 reading ±5 digits) from the manual 50 mA = 0.05 A >> accuracy is ±(1 mA ±5 digits) >> 50 mA ±50 mA !!! Remember, those ±5 digits mean ±50 mA, because the smallest digit represents 0.01A. And that means that you can see a value of 0.00 to 0.10 A when you measure 0.05A (50 mA). Choose meter 10X needed resolution. Here, res = 0.01A, so use for measurements > 0.1 A. But if all you need is a rough measurement, such as finding that a parasitic current is more than 100 mA, but you don't care what the exact value is, then this will work fine. But if you are trying to find if the idle current is 50 or 100 mA, this might not be a good choice.

Q: The Fluke 325 spec sheet shows current range as 40A - 400A for both AC and DC. How do you switch the meter from 40A range to 400A range?

Stephen, you peaked my curiosity so went looking on the Fluke site. It was worthless so got out the unit and tried it on a DC telephone line from a hydronic zone valve to the water heater and it measured .46 amps (probably in milliamps) on the meter. Then switched it to the AC line and clamped around a line leading to a 500-watt work light and it measured .05 amps (which should have been no more than 15A. I think the difference has to do with the base as the DC amps should certainly be less than the AC amps. Anyway it does measure but had to learn how to use it.

Q: DOES THIS TESTER TEST DC AMPS

Yes it will. Unfortunately if you are used to the great 337 that had their own switch positions this one you have to learn to push the "zero" button to put it into the DC mode. It is the same with AC and DC volts. Button must be pushed to change to DC. Hope this helps. WW

Q: does this measure as little as 5 amps dc?

Yes it will read as little as .01 amp dc
