    Cap ESR reading is it right?

    The cap is an ELNA LP5 35V 6800 uF with a reading, out of circuit, of 0.01ohm. The meter is an ESR-2501A.

    The capacitance is 6270 uF using an Iso-Tech 9023.

    Does this sound about right for this size cap?

          Thanks, so looks like the ESR is likely to be ok.

                  PS5 HDMI port diode reading?
                  by SuperAman
                  I did an hdmi port repair for a PS5 and I lost the small diode z71 SOD923 on the back of the port. I did a trace repair for pin 19 of the port as well. Without the diode I get no display at all. I tried replacing the diode twice but after I get flux on it the marking comes off so I can't tell if I have it on the right orientation. When I measure I get a reading of 1(open) and 923 in diode mode. Is 923 a normal reading for these and also which side should the reading be with regards to the arrow on the board?...

                  0.00 ESR reading on a capacitor
                  by Fuzzy Fix
                  Howdy all I have a 90uF Capacitor 200/275 VRMS and measured the ESR . Reading says 00.3 Ohms and about 1/2 a second later 00,0 and says low ESR (Really No Kidding).
                  I have checked it on the multimeter and reading is 94.7uF well within soec as ir has a 25% tolerance on it.
                  Can anyone advise me is this capacitor likely to fail in the near future or still good to use.

                  no 3v and 5v section voltage reading
                  by kalilinux25
                  Hi my board is HUSK MB 11309-248.4TU05.021

                  The board is plugg and consuming 13 milliamp
                  measuring the 3v coil no reading and the 5v coil no reading


                  Ive measure the pins in PU4103 ( RT8223M)

                  APC Smart-UPS 3000 XL (SUA3000XLI) not reading voltages well
                  by camisao
                  Hello there,

                  I have a issue with a tower UPS 3000XL with also an external battery tower that has almost new batteries and very little use.

                  A week ago it started entering boost mode because the read line voltage was below 210VAC, when it was in fact near 225 VAC.
                  The battery voltage was also low (48 or 49), when in fact the batteries are fully charged to 55.1 VDC.

                  I opened it up up, cleaned and tried a reset.
                  I updated lower transfer voltage to 196 with apctest and then used the serial port to adjust the configuration with a terminal in Prog mode...

                  A2141 PP3v3_G3H_RTC_X Diode Reading .104V Voltage 3.39V
                  by abajor
                  Have an A2141 which is reading about 5.2V 0.07A on all USB jacks, started doing the measurements.

                  PPBUS_3GH diode: measures good .45V
                  PPBUS_3GH Voltage: maybe not so good 12.25V maybe bad T2? Unit did not come up in DFU on configurator.

                  The weird so far is
                  PP3v3_G3H_RTC_X diode: .104V (WTF?)
                  PP3v3_G3H_RTC_X voltage: 3.39V (Normal)

                  Stopped there attempted reverse voltage injection at PP3v3_G3H_RTC_X with 1V. Instead of the circuit sinking any current, My PSU suddenly reads 3.4V with no current draw.
                  Not sure what any of this means...
