    Need u'r opinion about ESR , should we have it?

    I have reading on few forum and blog that sometimes suggest us to test the cap with ESR, so i'm just curious about ESR meter. As my hobby to repair in computer ( mainly laptop ) do we must have a ESR or not? Sometimes i want to have it , but i'm just curious is it help us more better or not ? when we do repair or troubleshoot ? Pls give your opinion about this because i know, a lot of experiences member in here that have been using ESR ( I guess )

    PS:
    Maybe this is stupid question but i need you opinion, ( i don't have and never try this instrument, who knows i'll buy it after read opinion from you )

    Regards

      hi,

      i bought one (BLUE ESR Meter) but i don't find it useful yet in repairing laptop motherboard.
      technician who recommends it, it is most useful in testing electrolytic capacitors.

      hope this helps

      regards

          To me, I use ESR meter to confirm that the cap is bad or not. You can replace the cap and if it fix the problem, then you move on, but for me I would like to know why the caps the I removed has correct capacitance but they do not work. It is just another tool. I built one, I l also have LC-75.

              degutji,

              are you referring laptop repair?
              laptops doesn't have much electrolytic capacitors. mostly ceramics and tantalum.

              or maybe i'm wrong and someone will correct me and share how to use effectively this ESR meter in testing ceramics and tantalum capacitors.

              regards

                  I think it is a waste of money. If you have oscilloscope you can buy a component tester device to measure the quality of the ele.cap. and it works fine.

                      Thx to all for your respond,

                      i do repairing laptop, PC just a little. Conclusion to me, i don't need yet maybe someday

                          Is it possible to test small ceramic disc capacitor with analogue meter?
                          by chth96
                          I read EBOOK of Testing Electronic Component and found that

                          "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
                          Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
                          It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

                          Is it really possible to test small ceramic disc capacitor with analogue...

                          by sam_sam_sam
                          I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board

                          I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...

                          Changing the scale of an analog meter
                          by jorpec
                          Hi

                          I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
                          I wonder how i can accomplish this so the meter would be precise at any temperature ?

                          Thnaks

                          How an incandescent light and a ESR meter ** friend**have a machine blowing fuses
                          by sam_sam_sam
                          About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well

                          Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for

                          Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer...

                          EDMI ATLAS MK10 Electronic Meter Discussion
                          by Stephan Mathers
                          Greetings, new guy here but always interested in the crazy universe of modding

                          We just finished construction of around 25 vacation houses, all inside the same private area.
                          Each house has 3phase power , and we bought an atlas MK10 meter for each house (25 meters total ! )

                          The metering on a per-house basis is done privately. Its not done by a utility company. The utility company will only charge us for the total consumption of all 25 houses together.

                          Id like to do a small modification on the firmware of our MK10 to make it easier identify each house's...
