Page 7: Refractive Index And Brix
2. Refractive Index and Brix The In-line Refractometer CM-BASEα is a refractometer that detects the Refractive Index of a sample and outputs the Brix(%) value on the display. (1) What is refractometer? When a straw is placed into a glass filled with water, the straw appears to bend. When a straw is placed into a glass filled with sugar water, the straw appears to bend much more sharply than in the case of water alone. -

7. External Output ◇ Turn off the power (DC24V) when connecting the cable from the terminal. WARNING The CM-BASEα(A) transmits data via 4-20mA signals. The CM-BASEα(D) transmits data to a computer via RS-232C. (1) CM-BASEα(A) The provided cable connects to the base of the CM-BASEα(A), and it provides power (DC24V) to the instrument and transmits Brix data via DC 4-20mA. - Page 14 Computer Output ① Computer - Data Setting Download a terminal emulator for PC serial communication.

Fire, electrical shock or burns may occur. To purchase replacement power cables, contact an Authorized ATAGO Distributor. ① Make sure that the cable is properly connected to the port. ② Once the power (DC24V) is turned on to the instrument, either the green light or red light will come on. -
Page 18: Measuring Brix(%)
9. Measuring Brix(%) ◇ DO NOT measure any sample that can damage the prism or the sample inlet unit. Sample temperature should be kept between CAUTION 10˚C and 50˚C when the power (DC24V) is turned on. ◇ If the sample solution could potentially stain the prism, immediately clean the prism after measurement (following the instructions on page 22 of this instruction manual). -
Page 19: Zero-Setting
10. Zero-setting m Before zero-setting, confirm that the prism surface is clean. ① Confirm that the sample inlet unit is properly connected to the piping. ② Let tap water flow through the piping. ③ Supply power (DC24V) to the CM-BASEα referring to the procedure described in Chapter 7. -
Page 20: Bias Adjustment
11. Bias Adjustment The bias adjustment feature allows the instrument to display readings that have been adjusted by a fixed value added or subtracted from the actual measured value. Hold down the ZERO key for approximately 5 seconds to activate the TEST mode, and the displayed value will start flashing. -
