If you want to measure how a battery charger works (the actual CC/CV curve used to charge the battery) you would insert the EBD-USB between the charger terminals and the battery, not between the USB power supply and charger power supply input. For this you need to come up with some cable adapters as the meter only has USB ports.
Here’s how you would connect it (just using a different meter and lots of unnecessary adapters, keep them to a minimum and use as short and thick cables as is practical)
It is done the same way as maukka so nicely illustrates. Just be aware that there will be some resistance in the setup, i.e. the charging will not be exactly the same as without it.
Just found this forum and this post. I, for the life of me, cannot get my EBD-USB+ to work … I think my computer see’s ‘it’ … it autodetects com port 3 (and if i change the com port in the deveice manager settings the software seems to ‘follow’ the new com port) but the software simply will not connect to any load I put on it … i get nothing.
I can confirm that the load tesing, USB female slot works, as I can attach an actual load to the male usb out and it works off the source battery i attach to the usb female input plug. And if i assume that the micro-sub port to attachj ti to my computer, then i am not sure what’s wrong.
I kind of feel like it’s a computer/com prot issue … i’m using windows 10 and i’m not sure how it treats a USB plugged in device as a com port (is there a setting i need to change). I will try to try using older EDB-USB software and i will try a firmware update … if i click on the firmware update buttonm in the software, it actually doesn’t let me select any type of device …o perhaps my micro-usb connection isn’t working? I’ve tried 2 different cables but will try a third to see if that works.
I have EBD-USB(not plus) for about 2 years, and I’m not happy due sudden disconnect from COM-port. Software indicators become frozen, and device continue to draw current. Very disappointing to begin spoiled test again and again. Tried everything, different PCs, Windows, cables, drivers. Defective device? Don’t know. Not using now. Got TEC-06, run it w/o PC connection.
Sad. Good device...
Btw, to clean out COM ports on Windows 7/8 (not sure abt 10, make backup first) there is a script, just as example:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter] "ComDB"=hex:00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00
COM assignment will be reset, make sure you don't have vital things there (printer, modem, etc)
Hi friend. I have ebd-usb+. But i have a big problem. I changed the calibration setting of the device.But dont fix it.Can the device be reset? Can it be restored to its initial settings? Can you help me pls.
If you use the EBD-USB+ software (EB Tester), I think in the Calibration menu, there is a Reset button — have you tried it?
(I have not personally tried calibrating or resetting my EBD-USB+ though, so kindly report here if the Reset button did something for your unit).

EB Tester software has another update (it now indicates Build 2020-01-01) - as usual no changelog and likely just some very minor unspecified changes since the executable file seems to still be similar file size)
(when installing, I find that you need to uninstall or rename/delete the old EB.exe file (default in C:\Program Files (x86)\ZKETECH\ folder), otherwise, it didn’t seem to update my previous EB Tester Software even when it appears to install successfully…)
I have a couple of questions ( for HKJ ) about this tester for batteries is possible to just use the current measuring capabilities of this tester with out using the on board load ?
How easy would it be to power the battery voltage separately from the battery tester from the USB connector to the computer
The reason I was asking about if the load of the tester could be disabled is because what I have in mind doing is setting up a battery backup power supply charging and discharge logger for power supply output
I have there battery tester machine and just love using it for that purpose but I do not want to modify this tester
I would prefer to use this device and modify it for the purpose that I was just talking about
