Many devices document Modbus addressing starting from 1 but in reality it starts from 0. LM uses 0-based addressing.
When reading from address 1 you are actually reading one register from phase 1 and another from phase 2. Together they form a value that looks valid but it is not. This is why phase 3 reading is not working.
Use read test, set datatype to float32 and address to 0. Find the correct swap mode that produces a valid result.
