1. Instrument connectivity for diagnostics
The K-Patents Process Refractometers PR-23 include an Indicating transmitter unit (DTR), which offers the
most convenient channel to diagnose and troubleshoot faulty operation of the refractometer. The same
information can also be obtained through an internal built-in web server using a laptop. Furthermore, FC-11
Field communicator can be connected to the transmitter for data logging and to obtain more detailed
diagnostic information. The FC-11 is specially designed tool for service, troubleshooting and configuration of
the K-Patents instruments.
Figure 1
Instrument diagnostics can be obtained through the transmitter, a laptop or FC-11.
The instrument’s web server can be reached through the instrument’s IP-address. The default IP-address for
the PR-23 series is 192.168.23.254. The FC-11 automatically connects to the instrument if the address has
not been changed. To obtain connection between instrument and laptop, type the IP-address on the
search/address field of the browser. The webpage opens in all common web browsers. Sometimes the IP-
address of the computer needs to be configured prior to establishing the connection, especially if there is no
router between the instrument and the laptop.
1.1 IP configuration for Windows 7
The connection to the instrument is established using a router between the laptop and the instrument. In the
event no router is available or there are other difficulties in connecting to the instrument, follow the
instructions below.
The IP-address of the computer can be configured through Windows control panel by selecting Network and
Sharing Centre, adapter settings and choosing LAN connection properties with a right click of the mouse (1).
Then select the Internet Protocol Version 4 (TCP/IPv6) and click properties (2). This will open a window that
allows configuring the IP-address. The first two sets of numbers in the IP-address should be the same as in
the sensor’s IP-address, however, the IP-addresses should not be totally identical (3). The Subnet mask is
