● Range change command (RM/RE/RA)
The command executes range switching.
The result is written in fl ash memory.

For GC6

a b c d
a: Stream number (1 to 31 or 01 to 31)
b: Peak number (1 to 99 or 01 to 99) *Relative peak number
c: Range number (1 to 31 or 01 to 31)
d: Analyzer number (1 to 9 when M comes in the second digit, and 1 to 240 or 001 to 240 when E comes in the second digit)
● Reference peak overwrite command (YF)
The command executes reference peak overwriting.
If the specifi ed stream number and peak number, as well as the reference peak stream number
and peak number do not exist, the command does not execute writing.
The command executes writing regardless of the processes. For the external linear model, it
overwrites the reference peak database at the reference peak 1 or base level.
The result is written in fl ash memory.

b: Peak number (1 to 255 or 001 to 255) *Relative peak number
c: Stream number of the reference peak (1 to 31 or 01 to 31)
d: Peak number of the reference peak (1 to 255 or 001 to 255)
e: Analyzer number (1 to 240 or 001 to 240)
