    La-k035p photo of moved components please

    Hi everyone

    Somebody has a photo of the correct order of this resistances?

    I made a mistake and moved 2 resistances, I put them like I guess they goes but I'm not sure and not boardview or schematic is available

    Mobo: LA-K035P

      Based on the 25Q128JVSQ flash to the right side of these parts, very likely the resistors are there to stop ringing noise on the communication SPI bus lines.

      Remove all power. Meter in resistance mode. Measure the resistance across the contacts of each of these resistors that are unknown. What are their values in ohms?

      Meter in diode mode. Touch your meter probes together and you should hear a tone beep. Touch one of the resistor pads with one meter probe - keep it fixed; hunt for the other side of the trace with the other meter probe on each pin on the flash IC. Test each pin till you hear a tone beep.

      Make a table of each pad to IC connection and post the list here.

      Guessing that the resistors will be 22 - 33 ohms each and they are applied onto the signal lines to dampen the ringing noise.

          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 ?

          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 ā€œEā€ stops and one switching power (24 volt) supply and a transformer...
