1. Get ready the PC with COM port (RS-232C) running on Windows 95/98/ME/2000/XP operating system, as well as the RS-232C cross cable.
2. Start the unit with the RS-232C cable connected.
3. Start the terminal software. (The freeware readily available on the Internet will do.)
4. Make the following settings.
Baud rate 9,600 bps
Data LENGTH 8 bit
Parity bit None
Stop bit 1 bit
Flow control None
5. If the settings are correct, the terminal software indicates "ERR" against pressing of the "ENTER" key.
6. After the settings are done correctly, it is possible to make an adjustment by typing in the command shown in the table below and pressing the
"ENTER" key on the keyboard.
7. Command entry is successful if the terminal software indicates "OK" when the "ENTER" is pressed. If "ERR" is shown, retry to enter the command.
8. Send the process mode switching command to switch from the RS232C operation mode to the process mode.
KRSW0001: "ERR" is returned.
KKT10037: When "OK" is returned, the process mode becomes active. When "ERR", start over from KRSW0001.
9. Send each adjustment command.

value of G [(default of standard value 4) x (G of standard value 6) /
(default of standard value 6)] and adjust RB to the standard value.
5) Set the specified gradation for standard value 3. Set the correction
value of G [(default of standard value 3) x (G of standard value 6) /
(default of standard value 6)] and adjust RB to the standard value.
6) Set the specified gradation for standard value 2. Set the correction
value of G [(default of standard value 2) x (G of standard value 6) /
(default of standard value 6)] and adjust RB to the standard value.
7) Set the specified gradation for standard value 1. Set the correction
value of G [(default of standard value 1) x (G of standard value 6) /
(default of standard value 6)] and adjust RB to the standard value.
8) Write the adjustment values with MSET0003 command and turn off
AC power.
