The LM317 is quite bad as a current source. Its internal reference is only good to a few percent and as it warms its self up from the current it will have some temperature drift. Regulating from the 9V battery to 5V with an added regulator device will make this better.

I like this little monster! If you cover the decimal point with black paint inside the display, then the reading on the screen is millivolts and no more confusion. The dropout voltage of the LM317 determines the highest resistance that can be measured. For 100 mA current, the highest resistance is given by the equation Rmax=10*Vin-30. For 5V, you can measure up to 20 ohms. For 9V, maximum is 60 ohms. However, power to your resistor is W=R/100, so heat will change reading. A 60 ohm resistor would receive 0.6W! But that isn't possible with a 9V rectangle heavy duty cell, they instantly drop to 5 or 6 volts under 0.1 A load. Alkaline cells would drop to about 7-8 volts under the same load.

Pretty beautiful job, dude! Really well done! 😃

Thanks for sharing. I would make it a 4 wire setup, so longer leads are much more useful.

This is not a good way of measuring such low resistances. The 4 wire measurement method is better. The resistance of the probe connection and the test lead resistance is going to through this off.

Great idea, many thanks.

very nice video. 🤓🥳 the test resistors workout well and 1% values or less make a great indication. 🧐 thanks a lot. 🤩🙂

i dare you to make a terraohm meter :D just so u can measure resistance of wood and other insulators. i found that discharging a tiny tiny capacitor can be helpful. for example a mosfet gate. i was able to rapidly discharge it by connecting it to wood, but only very slowly through my fingernail.

Night and simple design Thanks for sharing👍😀

Hi Myself bharath. A big fan of your channel. Am sorry am not good in English, sorry. I request you to make a device, I mean DC backup for my wi-fi router. Kindly make a backup using lithium batteries or 12 volt lead acid battery and output 12 volt 2 amperes. And it should work like uninterrupted power supply. Am requesting you to make this because always power failures at my home and no internet. If you make a uninterrupted DC power backup, it'll be very useful to me. I guess most of the people need such device. I have charging modules, step up modules and step down modules but always I fail when I make a circuit with such modules. Hope you understand my English. Thanking you.

Nice project 👍

Eres un maestro enceñanos hacer un capasimetro

Remember everyone when your measuring resistance is that low even resistance of the alligator clips is and can be significant some positive method of clamping tight is preferable so that you know that you're not introducing error into your measurement

How about a part number for the volt meter? Also, was the meter connected during calibration?

very well done video and explanations

That led display would drain the battery like there's no tomorrow.

do you have any link for the 5 digits led display ? thanks

Thanks for the idea can you please make some simple device like this to measure low value capacitors and inductors.

Can I measure resistance from 50 micro ohm to 200 micro ohm? Actually I want measure contact resistance of 400kv circuit breakers

In digital micro- ohmmeter how to troubleshoot. Not getting reading

Are using a 13 Ohm resistor or a 470 Ohm resistor? I see a 470 Ohm resistor in the video but you say it’s a 13 Ohm, or do you mean that you set the 470 Ohm resistor to 13 Ohms? Pardon my ignorance, I’m new to electronics but I want to learn. Please clarify. Thank you

ممكن تصنيع اوعمل عدادفوليته بواسطة لدات ماهو الايسي المستخدم وهل يوجد مخطط للعداد

Kasyan calibration bad ...low prescion ...

Would this be suitable as an ESR tester for capacitors?

Possible to use this as a capacitor ESR meter?

Good

can you pls make a good esr meter

We can find bord short in this divide

Where is the zener tester did you delete it?

This is only as accurate as your amp meter and voltmeter which you are relying on.

How many

Nice

Old voice, please? ;(

Hi mam

6:00 ? 0.05 =/= 0.005?
