M30 - Jumpers for CT inputs (voltage/mA)

[raphaelcno]

Hello

I'm reading the description of the M30 board (https://www.kincony.com/esp32-energy-monitor-board.html). 
I see that it's possible to use CT clamps with voltage or mA signal. 
Can you tell me if the CT inputs on the M30 board are equipped with jumpers in order to choose between voltage and mA signal? 

Thank you in advance for your help

the jumper set for "mA" or "voltage" CT sensor. some CT sensor inside have connected resistors in parallel, so this is "voltage" type.

Thank you for your answer  

Can you show on this picture where the jumpers are located?

M30 not have the jumper, default use by "current" CT sensor. But you can also use "voltage" CT sensor, just "current" CT sensor will have a better data accuracy.
M16 and M16v2 board have jumper for setting.

Thank you for the clarification

Greetings.
I have successfully programmed my M16v2 board and it is reporting to ESPHOME, but the amp measurement graphs have a pattern that every 15 minutes the measurement drops to zero. I made some adjustments with lamda and it no longer drops to zero but the measurements continue to drop a considerable amount.
Attached is the image of the measurements.
