Hello, any thoughts if this thread title is plausible with basic explanation would be required as I am not familiar with these units?
It is capable of displaying 99999 counts...(please don`t mind the price)

I do have parts coming for really cheap 10 usd 33000 counts voltmeter, but that is sometimes not enough for what i plan to measure...

This is the module I would like to convert:östergesi-90-250-v-ac-48-x-96mm/7365039

Manual in pdf:

Thanks in advance for any usable info...
