    Re: ESR meter upgrades

    the test routines have been changed a few times over the past year.

    and no, it cant test complex analog parts like regulators.

      Yes.

        Re: ESR meter upgrades

        i got an EZM one of these, same as in post #446.
        And it was working fine.
        But i thought that it tested voltages; so bricked the chip.
        So got another chip and used a batch file to program it with "GM328x ESR tester (SVN684) - v2.zip"
        It now appears to operate well, except for one thing: after going through the calibration process, and the test finishes, it says that it is not calibrated.
        Any idea why it's not calibrating?

          Have you tried to run Selftest from menu?

            Re: ESR meter upgrades

            Yeah,
            Strapped terminals 1, 2, and 3, and removed them when said to isolate.
            Then it asks for a cap greater than 100nf between 1 and 3, so i give it 25uf.
            It then visually flashes the capacitance measurement on the LCD for two or three minutes.
            Then it asks for 10-30nf, so i give it 12nf
            It then displays the capacitance briefly.
            And then it displays "Test end"
            And then returns to the menu.
            Then i test a few caps and it gives good readings.
            Then i select "turn off"
            With no components inserted, i turn it back on
            It tests the battery correctly
            Then displays :"no unknown or damaged part?"
            Then "Not calibrated!"
            And then automatically powers off.
            If i insert a capacitor, and push the button before it displays the "not calibrated!" message, it tests the capacitor.
            So, is this calibrated, or not?

              instead of 25uf, use something like 220nf - atleast not more than 1uf.

              it should not flash for a few minuits - that tells me it's not happy.

                  Which one would you recommend? Or is changing the crystall a solution?

                    Re: ESR meter upgrades

                    i recommend this at the moment.

                    http://www.ebay.de/itm/182221397168

                    and a case!

                      Re: ESR meter upgrades

                      Dam the ebay seller is not shipping to Germany. This should be the same if i am right.
                      http://www.ebay.de/itm/GM328-Transis...cAAOSw0fhXki5S

                      And because RS is really pricy in Germany (more than 8€ for shipping) i want to ask if i can use this crystall. It is not a 10ppm.
                      http://www.ebay.de/itm/272367597610

                      And because i can not find my old programmer (i used it to programm Atiny 13A chips for my flashlights).
                      http://www.ebay.de/itm/172229590674

                      Now i only need a cheap source for the voltage regulator. If i did not miss anything.

                        all those links look fine to me just be aware that stuff from china is taking ages to arrive lately due too some shipping company issues

                            The Programmer has arrived. Now i am waiting for the Kit to arrive.
                            One question. Can someone check if i have found the right PMIC (https://www.conrad.de/de/pmic-spannu...html?insert=62).
                            A friend works nearbuy this shop and can get it for me. So i do not have to pay for shipping.
                            There was a second chip to increase the battery runtime but i can not find it in this shop. And i do not have the knowledge to check for a chip with similar characteristics.
                            Maybe someone here can take a look.

                              that's the part,
                              i'll take a foto later of how to fit it - because it's not the same as the lm431 it replaces.

                                And can you also help with the other chip. I think it was a 5V low dropout voltage regulator. But i can not find the chip at Conrad Elektronics. But maybe they have something similar that i can use.

                                        the AY-AT kit uses a 7550A regulator - it may be decent.
                                        i'll have to find the datasheet

                                          the 7550 actuually looks pretty impressive!
                                          so no need to change it.

                                            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...

                                            Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
                                            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 ?

                                            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...

                                            ps4 1215 model Changed port and encoder still no video?

                                            hi guys so i have this ps4 fat 1215 i believe ( the one with the ps4 pro/slim newer encoder ic ) so i replaced hdmi and 2 blown filters and still no pic so i replaced encoder and still no pic. i made sure port is solid even checked with a breakout hdmi and tested ground and data lines.. Filters are all good , though 2 of the newer ones are larger then the original ones i dont know if that matters ?
                                            Made sure under the scope encoder pins all look solid went over with fine tip and solder again. Idk but this thing is stressing me out..
                                            ps4 seems to boot fine blue light then solid...
