One thing I hope could be improved for the ZY1276 is the graph-plotting. Changing the speed requires going to the Settings mode, which means unplugging and replugging the ZY1276 while holding down the button.
I would have liked a quick way to change the graph speed while it’s in the graph-curve display mode (sometimes fast mode will help detect if the current being supplied by the USB power supply is consistent or there are micro-fluctuations in voltage…) Choosing slow mode also useful in certain scenarios. No quick way to toggle between faster and slower graph-curve display (unlike the Power-Z KM001 where it’s easy to change the curve display speed).
Hey. Oh so the new model could convert QC type c to PD? nice . Anyway on zy1276 . I have some questions. So I’m trying to use my load dummy. This one needs usb power to run. So. Could I just connect it to the meter while I use the output too for draining? Will the meter reads both outputs usage? So basically. Type c input to ZY1276. Then on output I use both usb a and type c. Say the type a uses 1A and the type c uses 1A. Will the meter reads it correctly? So it shows 2A? Thanks…
also… eh, when upgrading . the instruction says to check the factory reset on program while flashing. does it resets calibration? and if didnt check the reset on while flashing, does it keep the calibration?? i cant calibrate it since i dont have accurate meters / source etc
I’m not sure if using both outputs at the same type USB-A and USB-type-C will work properly… maybe you could tell us what happen when you did it (use a smaller current when testing, if you can configure it)
ill try later on when it arrives. anyway when upgrading . the instruction says check the “reset after flashing” on the program. does it resets calibration? and if i didnt check the “reset after flashing”, does it keep the calibration?? i cant calibrate it since i dont have accurate meters / source etc
In my case, the voltage readings of my ZY1276 didn’t seem to change (or if it did, it was too small that I hadn’t noticed it) before and after I upgraded its firmware.
Guys I have great news. So my ZY1276 just came in the mail. After trying it. I was so confused of the firmware version. Its already on 3.36D . And it appears that I have the new ZY1276P version (I know cuz when it shows the model number when you holding button bfore going to configuration mode) okay. So basically. I should be able to check emarker without PD adapter. No documentation yet. So idk. I’m waiting for my type c cables. Also. I’ve found a closed beta firmware . 3.36E (newer than stable) it removed some Chinese text. And vooc check . For beta testing QC to PD 2!! (He said the memory isn’t enough for new features so he needs to remove some to get some) . Haven’t tried it yet tho. He said something too about not using it with emarked type c cable. Anyway here’s the fw if you wanna test it. ZY1276 only!! I’ve flashed it successfully.
You’re right, i meant the voltage setting in the STM32 programmer software.
I do have the pogo pins, but can’t connect the ZY1273 to flash the firmware 3.1 on it.
