3-4. Printer Output Test (When Printer is Connected)
1)
Referring to the instructions in “1. Instrument Preparation” above, connect a printer
and turn the power on. Turn the power on to the RX-5000i. Make sure that the
opening message is printed.
2)
Apply distilled water on the prism and zero-set the instrument. Make sure that
“ZERO SET END” is printed.
3)
Measure the 30.00% Brix standard sucrose solution. Make sure that the sample
number, measurement values in nD and Brix, and measurement temperature are
displayed. (The items to be printed are selected in “1. Instrument Preparation.”)
3-5. RS-232C Output Test (When RS-232C Cable is Connected)
For Windows 95 / 98 / 2000 / XP

directly to COM1. Set up the communication parameters as follows:
●
Baud rate: 9600
●
Data: 7 bit
●
Stop: 1 bit
●
Parity: odd
3) Set the baud rate of the RX-5000i in the same manner. Touch “SET UP” on the home
screen. Touch “SERIAL,” and the protocol setting screen will appear.
4) Apply distilled water on the prism and zero-set the instrument.
5) Type in the zero-setting command “*ZERO” and press “ENTER” on the PC. Zero-setting
will be carried out.
6) Measure the 30.00% standard sucrose solution. The measurement data will be
