i want to connect two displays with one main unit wireless.
it works “nearly” 😉
one display is always changing its data voltage and current are correct for about a second, then changes to nonsense.
the other one works completely fine.
i think i made a mistake within the settings. i am using “FCH” and “SFH” set to “46”. this might be wrong. can you please tell me the correct setting?
thanks! chewieDrokKeymasterJanuary 27, 2021 at 3:21 amPost count: 2971
SFH is used to search communication channel. If you want to connect
Please make sure power on one meter and one measurement module only in case interference. Then please search communication channel in SFH . Within channel 0 -128, you can check which channel will display correct voltage. Then set that channel as FCH address.

i did exactly what suggested. in “sfh” channel 46 is the only one, that shows exact voltage.
so i set 46 in “SFH” and “FCH”. disconnected this display. > connected display 2.
again, in “sfh” channel 46 is the only one, that shows exact voltage.
so i set 46 in “SFH” and “FCH”, again. works fine.
but as soon as i connect both modules to power, one is beginning to alternate voltage and current.
current switches from exact data to -588,8A.
i did this with an external battery. not connected to main unit via USB.DrokKeymasterJanuary 28, 2021 at 7:16 amPost count: 2971
When voltage and current changes, is the channel still 46? Would you like to take a video to show the problem?
