    DC Clamp Ampmeter

    Overall: 5 out of 5

    I constantly use this meter in the marine environment. It's great for troubleshooting battery banks with multiple batteries, solar chargers, and engine alternators. Voltage is only part of the story, and DC current completes the picture to understand where the amps are going. For instance, after you remove the charge source from a bank of three 12V marine batteries of different ages, you can instantly see if one of them is drawing current from the other two and for how long, perhaps discharging the battery bank that was just charged. I'm buying another one.

    AC/DC Amp Clamp

    Overall: 5 out of 5

    I've had amp clamps for years, and they are indispensable for any electrician. They are generally used for all AC applications, no matter if you service appliances, or install or service wiring in homes or commercial properties. You also carry a multimeter to read DC and Resistance. To measure DC amps, you must disconnect the circuit, and connect your mutimeter into the circuit. Max current is usually 10 Amps. More, and you just bought a meter. This meter does everything your AC amp clamp does, but also does it with DC. No need for a 2nd meter. No need to disconnect the circuit, and worry about touching hot wires, or frying your meter. If you want to know how much current anything on your car or other DC operated systems is using, just clamp it on. On your car, to check how much current your car lights pull, turn off everything except your lights, and clamp onto your battery cable. You can do the same for your car audio system. Turn off your lights, turn on your audio, crank it up and read the meter, car off, of course. Car running, reverse the meter and read the charging current from alternator, still just using the battery cables. Of course you can get into smaller stuff by isolating it, and then clamp onto smaller wires. Back to the cables. If your car, or any type of vehicle battery is going dead, and you suspect an electrical leak, this meter will read the most minute amount of current leaking. It also reads very high current loads, more than a car can produce. It also is an ohm meter. All this with digital accuracy. This is the best all around meter I've ever come across. Everyone who knows how to use it should own this meter.

    AC-DC Amp meter

    Overall: 5 out of 5

    I purchased this for my work. I am a teacher for a technical college. All the features that this little meter comes with make it an excellant purchase. I've been looking for a small meter that checks both AC and DC amps. We tried it out the day I received it and it performed magnifcently. I give this meter a 5 star rating.
