Measure-
ment start
Sampling E Triggers the measurement when the trigger mode 
is set to HOLD.
Trigger *TRG
Zero correction ZR Executes the ZERO correction
The execution time is approximately 4 seconds.
Wavelength set-
ting
WL data Sets the measurement wavelength.
The setting range depends on the connected sen-
sor. Unit nm
WL? Query reply : WLdddd

Calibration wave-
length selection
WLC0 Sets the calibration wavelength to the point [0].
WLC1 Sets the calibration wavelength to the point [1].
WLC2 Sets the calibration wavelength to the point [2]. 
Points [1] and [2] are options.
WLC? Query reply : WLC0 to WLC2
Calibration wave-
length reading
WLCF? Reads a wavelength and a calibration sensitivity 
correction coefficient at the set calibration wave-
length point.
