@Justin Bunn Excellent Video clip! Sorry for butting in, I would appreciate your initial thoughts. Have you tried - Franaar Shining Shape Formula (do a google search)? It is a smashing one off product for revealing the secret to repair your electronic devices without the normal expense. Ive heard some extraordinary things about it and my good mate called Gray at very last got astronomical results with it.
Thank you sir you saved my day my amp indicator was not working well. You said about the fuse . I checked it and it was broken. I replaced it and now it works well. Thank s again
Thank you so much for making this video! I'm a primary school teacher and I needed to know the sort of meter to buy to read currents in a simple circuit, this video helped me a lot!
thank you! I've never really used a multimeter before for checking current, and I couldn't find anything on youtube detailing the use of measuring mA. With the aid of your video, I finally determined that I was actually trying to do it right and I was not getting a mA reading. I opened it up and the fuse had fallen out! so it isn't always blown! it seems during shipping they weren't very careful with it! THANKS!
It's probably more technical than you wanted to get in this tutorial, however, one important point was missed. The internal current shunt used in virtually all multimeters presents a problem with current measurement ranges called “burden voltage”. This is the voltage that the internal current shunt resistor drops as you pass your circuit current through it.
Thanks for the last comment in the video :) I was wondering why my multimeter did not give an indication for current. I opened it and found the fuse was blown!
Good tutorial and straight to the point. As a completion, may I ask in the range of 200 mA, what is resolution (i.e., the minimun current the instrument can detect)? Could be 2 mA (1% of the range)? Thx Manlio
hi I measure current of a device and I connect the black wire on com and red on 10A and my measurement was 0.08 but when I put the red wire in the other hole and set the multimeter on 200 m setting it displays me 000 and if I change to on 20m against the same? what happens?
Thanks. Nice and to the point with no jazzy music and logos and "please like and subscribe yada yada". I want to measure current flow from my 3D printer on the control board but my meter only goes to 5A and I'm not sure if the current is above that for the hot end, especially as it's a 20A power supply. Think I'll just test the volts.
I do have a question, If the current I'm testing is constantly changing up and down. How would I get an average current reading over say 2 mins - assuming the change is repetitively constant (i.e. 0 to 0.6mA 20 times a minute). Thanks.
Im still a bit confused. When you have an amp rating above 10 amps will that method still work or do I risk damaging the multimeter again? Are electronics labelled which how high their amperage is supposed to go? And if so, should I keep track of it so that I don't damage the multimeter? So when I do have a rating above 10 amps, what do I do then? Or is that dependent on the multimeter?
Good job! Question when I turned my multimeter dial to milliamps to test the LED, the LED went off, Then when I turned the multimeter to OFF, the LED went back on. If you know why, please help me out. Thanks!
+Philip Watson LED's need a certain amount of forward voltage to light up, and the multimeter would (shunt) be eating some of that up, and the voltage drops too low for it to illuminate.
Also cheap meters can also blow up in your hand as they use questionable materials. Make sure their certified safe for the voltage/amperahe your working on
thank you for this tutorial... but i have a serious question... i have the same multimeter but it dosent read ac current correctly... is it because this multimeter is only to read dc current? as i have seen other multimeter with a different ac and dc amp knob.. please help me. should i buy a new one?
As he said you need to make sure fuse is not destroyed ( It should word if your multimeter displays Voltage but Amperage is not displayed.) Hope It will work :)
Ps. It could happen if you by mistake connected Multimeter wothout any Ohm resistance (not connected any LED or heat system. (You probably made a shortcircuit and burned the fuse as I did with exactly the same multimeter.
Shadow no its showing me the dc current ampere but in ac line its value is fluctuating and is not accurate.... in my multi meter at the current section there is only the sign of dc, no ac sign is there... i think that its only to use in dc electricity
+Parasar Bhattacharya Well you have not said that you were usinv it in AC, I was pretty sure you were talking about DC :). Maybe you bought faulty device.
Shadow no no acrually it can onlu measure dc amps, not ac amps, but can measure dc and ac voltage both.. actually its a cheap multimeter... it costed me nearly 10 dollers. its a cheap machine so they did not gave any section to read ac currnt
I understand this, but it seems like something you could forget very easily and fry your volt meter. Bullshit, why does ever thing in life have to be so difficult!
