Connect the Sanitary OEM Refractometer to a 24 V DC supply. For more information, see Power supply and Refractometer wiring.
Check that the instrument powers up properly. This is easiest to check by measuring the milliamp output, which should be at 4 mA after the first startup. It is also possible to see a faint blinking amber light when viewing the prism at an oblique angle.
Connect the instrument to a computer with an Ethernet cable (RJ‑45 to M12 type). After the instrument has powered up, use a web browser to open the instrument homepage. For more information, see Ethernet connection.
On the homepage, check that the serial number of the page corresponds to that on the instrument nameplate. If you have difficulties connecting to the instrument, see Troubleshooting connection.
