AC Modbus Split current transfomer

HI Guys

I have written many emails to you with no response

Also out of the box it was defualt to ID 12 this was a feat to find out untill I connected to t3000. Defualt to make it easy should be 1 on a brand new device. These things make it hard to connect.

I have found the CT need bigger timouts than other modbus sensors as the replies are quite slow which have resulted in many hours of trying to get this device to read on other modbus software.

TCP ConnectionTimeout 3000ms (3s)
Between connections 100ms
Between poll cycles 1000ms (1s)
So communication with this device with these timing are a win.

My issue now is the range from your data sheet
104 1 0-10 R/W the range of current Full Scale Amps Setting
0 = 10A
1 = 20A
2 = 50A
3 = 100A

Reg 104 is incorrect as this is what it reads
testq 192.168.1.111 502 12 104 HoldingRegister Read =26624 OK: [0C] 03 0068 = 26624 2 False False

26624 as the value in that register is incorrect as it should be 0-3 thats the reading I get?

Can you confirm this
from data sheet Calibrate current Write the real value to register 100
but yet 100 is a read of current?

Thanks

Chris
