Performance Test of RX-5000i Automatic Digital Refractometer
Preface
The Operational Qualification (OQ) procedures of the RX-5000i Automatic Digital
Refractometer are described herewith.
The OQ performance test is to be executed by an operator who is familiar with the operation
of the RX-5000i. For daily inspection and maintenance, refer to the Standard Operational
Procedure (SOP).
1．Test Environment and Preparation
Turn the power on to the RX-5000i Automatic Digital Refractometer and let it warm up
for at least 20 minutes in an environment that satisfies the following conditions before
initiating the OQ test. The instrument may not perform to the required specifications if
tested in an environment that deviates from the criteria below.
Performance Test Environment
※The RX-5000i should be placed indoors on a level surface, such as a desk or table.

．Standard of Evaluation
A performance test requires a standard of evaluation.
Consider the stated accuracy level of the RX-5000i as well as the accuracy level required
The refractive index of a solution (standard sucrose solution, calibration
liquid) changes with temperature.
Ideally, the temperature of: 1) the prism of the RX-5000i; 2) the solution
(standard sucrose solution, calibration liquid); and 3) the test environment
should be equal for accurate measurements. It is recommended to maintain
the prism and the solution at a temperature that is within 4
away from the
