Connect the refractometer to the receiving system either with the analog output channel
or Modbus RTU.
The refractometer is now ready to measure and transmit measurement signals.
- Check the LED - green light indicates that the power is on.
- If Modbus RTU is used, change the RS-485 communication parameters and the Modbus unit ID as needed by using the Insight software and a USB adapter.
-
After the wiring is made, check that the green LED blinks when the master system polls
the values.
This indicates that the refractometer has successfully received a request and responded to a Modbus request made to its unit ID.
