Clamp Multimeter
Limitations of inductive multimeter or power Clamp Meter?
I need something to tell me if there is current or voltage through wires for AC/DC circuits. Will this "Megger MMC850" do it for both? I'm not sure if it will pick up DC current and if it only works half the time it's not worth it.
DC voltage will be up to 28 and AC goes up to 220.
What minimum currents can it detect? Is there one better for my application? Often wires will only be able to be seperated from other energised circuits by only a couple a couple inches.
Any information is greatly appreciated.
Suggestions for one to use where the wires run in close proximity to up to 50 others?
The jaws on most I've seen look too large to be usefull in confined spaces.
No, it won't do DC, amp clamps that do DC are about 5 times more expensive, due to requiring Hall-effect devices and circuitry. Note that the data sheet quotes a frequency response of 45 to 400Hz, which excludes DC.
I got a Fluke/LEM model LH41 clamp, does AC and DC up to 40A, great little clamp, about $400.
[[[REPOST]]]
This clamp is smaller than most clamps, ID=0.75", OD=1.5" (that's a jaw depth of 3/8") height is only 0.5"
Resolution in the low scale (4A) is 1mA

Blue Sea Systems Mini Clamp Multimeter $172.99 Blue Sea Systems Mini Clamp Multimeter . Measure current flow from outside the wire The Mini Clamp Multimeter is a compact and practical tool, accurately reading voltage and current when its jaws are clamped around any current-carrying wire. Most DC clamp meters have only a high scale of 400A or 1000A, and do a poor job of resolving the currents drawn by smaller loads like a single lamp or small pump. This digital meter covers the typical ranges needed on a boat. The 40A scale offers a resolution of 10mA, so it can not only measure current through small loads, but also detect some unintentional leakage currents that might appear because of faults in an AC or DC system. AC measurement is true RMS, a big plus compared to typical meters in this class that use simpler response systems, less accurate when measuring complex waveforms. This is important for marine applications, especially when measuring the output of an inverter. Range Setting: Auto Display Type: Digital Maximum DC Voltage: 6 |
