All refractometers are shipped with the factory default IP address of 169.254.23.33.
This address belongs to the Zeroconf addresses (as defined in IETF standard RFC 3927) so that it can easily be reached from a stand-alone computer as shown in Figure 1, usually without changing the network settings of the computer.
This address remains in the refractometer even after a different IP address has been set. The refractometer answers in the address that is first called up after startup.
| If there is more than one PR-33 in the same network, this address cannot be used. See Configuring refractometer network. |
Change the IP address of the refractometer through the instrument homepage. See Instrument homepage.
