    Default Viasho Driver potentiometer identification?

    Does anyone know the exact function of each of the pots on this Viasho Driver please?

    There are 2 sets of pot's huddled together, 5 in total.

    One set of pot's is in a PCB screen print marked box called TM1 and are marked 'Show' and 'CTRL'

    The other set of 3 pot's are next to a big screen print marked CURRENT and are marked I_C1, I_S and I_C2

    I emailed & PM'd Frank a week ago and have heard now't back as of yet

    Any help appreciated.
    Thanks
    Jim

    It is tricky because even though the pots are there won't mean that they work or do anything. In my case I needed to add a resistor that then enabled a pot to work to set threshold current on my lab supply.

    Surely someone out there must have an idea as to what these pot's do ?

    Please

    And, yes Dave the soldering is pretty shocking. The original wirings going into the screw connector block was absolutely awful when I first opened the driver.

    The quality of Chinese soldering somehow () drops extremely when a cover with warranty sticker will be placed on it. Like this driver from another well known manufacturer.



    But the OEM drivers from both companies with the PCB in plain sight look ok. The OEM Viasho driver that I own looks pretty well made.
