4.1.3 SF Command
"SF" command
The measurement starts when this command is transmitted to the instrument.
When measurement is ended, the measured data is returned with text data from the instrument.
① Transmission from computer to the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR
After activating the circuit of RS-232C, the computer transmits the character line
"SF" (ASCII code 53H 46H) and subsequently Cr (0Dh) and Lf (0Ah).
② Check of reception in the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR
When the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR receives "SF"+(Cr•Lf), it returns "OK"+(Cr•Lf) as a
check command and the measurement starts.
· In this manual, Cr• Lf was used as the delimiter but Cr is usable too.
