Aug 8, 2024 · Engineers use foot-pounds to evaluate the performance and efficiency of mechanical systems, ensuring components are designed to withstand specified loads and operate effectively within given parameters.
Feb 1, 2013 · The "setting" is what we call the range, or the "full scale value". It indicates the highest value that can be read without being "out of range". The reason the readings look different is that the precision changes. Specifically, .600ma is the same as 0.6ma.

2. Verify the ratings you’re working with.
As often as possible, I don’t skip these safety steps before proceeding to measure battery amps:
3. Check the fuses.
Before starting, never forget to check whether the multimeter’s fuses are still in working condition. To do this, insert the red lead into either the amp (A) or microamp (mA) terminal, depending on which fuse you want to examine. Afterward, turn the multimeter’s dial to any position other than the one with the amps symbol. The device should emit a beeping sound and display the words “LEAD” – at least, that should happen if you’re checking amperage with a Fluke multimeter. That means it’s good...
4. Insert the red lead into the amp (A) terminal and the black lead into the ground (COM) terminal.
I recommend always using the amp (A) terminal first when getting an amp reading, especially if you’re unsure whether the source has a high or low current. Why? Because settling for the lower microamp (mA) terminal from the start raises the risk of blowing its fuse, which is only rated for that lower amperage. If you want to measure the current draw of an appliance that you are confident has a low current rating, then you can insert the lead in the milliamp terminal instead. With that done, yo...
If you want to measure higher amperages, you’ll need to use clamp meters, which will need a different set of instructions. Take note that some people may say you need to “determine amps with a clamp multimeter” when in reality, they’re actually referring to clamp meters. The point is: don’t be confused about the two. Always verify this first, and b...
Testing the cold cranking amps of a car battery Let’s say you want to check whether the cold cranking amps displayed on your car’s battery’s label are correct or you’re testing the battery’s overall health. This is one good way of doing a multimeter car battery checkup. I’ll use a standard 12V battery setup for these steps: A couple of tips worth t...

Mar 22, 2024 · How to Test & Measure Amps. Check your battery or breaker’s nameplate to find its maximum amps, and ensure your multimeter is rated high enough for that number. Turn off the power to the circuit and connect the circuit’s wires to the meter’s probes. Leave the probes in place for 60 seconds.
