Set Up
- Unpack the instrument from shipping carton. Retain packing material for future
storage/protection/shipping.
- Note the following accessories:
User Guide
PC Interface Software Disk
Custom Channel CD
Serial Cable
Power Supply
Calibration Oil
- Place the instrument indoors on a solid surface in an environment where
the temperature is stable. Be certain that the instrument is not subjected
to direct discharge from heating or air conditioning vents, or water bath
circulator exhaust. Drafts can have an adverse affect on temperature
stability.
- Insert the appropriate plug end into the power supply and connect the
plug from the power supply into the back of the instrument where it is
labeled “5 VDC IN” (Fig 1). Supply voltage: 100 - 240VAC 47/63HZ.
- Turn the r
2
i300 on by activating the power switch located on the
instruments back panel located next to the power input connector (Fig 1).
- Allow the instrument to reach a stable operating temperature in the on
position for a minimum of one hour before attempting calibration or to
measure samples.

Sample Analysis
Cleanliness, sample quality and sample temperature equilibration are essential to obtain the
greatest possible accuracy from the r
2
i300 refractometer. Highly viscous samples that may
contain trapped air bubbles can adversely affect accuracy. In these cases applying the sample
using a rubber spatula or other soft applicator to squeeze out the trapped air is required. The
following are the steps to properly analyze samples.
Apply the sample to the measuring surface (Fig 2).
Allow the sample to reach temperature equilibration with the instrument.
Press and note the displayed value.
To change the reading mode press the key and advance to
the “Reading Mode” option screen. To enter press .
Press either or to advance through the available
reading mode options. When the desired reading mode is dis-
played press to accept.
Examples of reading modes are:
“Brix – TC” = % Solids – Temperature Compensated.
“Brix” = % Solids.
“nD” = Refractive Index.
“nD – TC” = Refractive Index – Temperature Compensated.
