2.2 Measurement
Alignment Adjustment <<See section 3.5 for the operating procedure>>
This function allows adjustment of the optical axis of the instrument’s built-in
monochromator (spectroscope).
The instrument’s optical performance is not guaranteed until the alignment adjustment
function has been executed. Failure to perform this adjustment can result in distortion of
measured waveforms. Always perform alignment adjustment the first time you use the
instrument, if the instrument was vibrated when being moved, or if the temperature in the
operating environment has changed. Perform the alignment adjustment after a one-hour
warm-up.
Wavelength Calibration <<See section 3.6 for the operating procedure>>
Wavelength calibration can be performed using an external light source.
Auto Measurement <<See section 5.1 for the operating procedure>>
This function automatically sets the optimal measuring conditions for the input light and
displays the spectrum waveform. This function is useful when the characteristics of the
input light are not well known.
The wavelength range of input light that can be auto-measured is 350–1200 nm.
The measurement conditions that are set automatically are as follows.
1. Span (SPAN)
2. Center wavelength (CENTER)
3. Reference level (REF LEVEL)
4. Resolution (RESOLUTION)
Other measuring conditions (sensitivity, averaging times, number of sampling points,
and interval settings) are set to their defaults. The horizontal and vertical axes of the
displayed spectrum waveform are zoomed to an appropriate degree.
Single Sweep <<See section 5.12 for the operating procedure>>
This function executes a single sweep operation.
Repeat Sweep <<See section 5.12 for the operating procedure>>
This function performs repeat sweeping operation. It enables repeated, real-time
measurement of waveforms.
Marker-to-marker sweep <<See section 5.13 for the operating procedure>>
This function enables sweeping between two specified waveform line markers. You can
sweep an arbitrary interval on screen.
Segment Measurement <<See section 5.12 for the operating procedure>>
This function allows you to divide up items to be measured in units of previously specified
segments.
Allows measurement delimited by segments (portions).
Smoothing <<See section 5.17 for the operating procedure>>
This function attenuates the noise in the measured waveform. By using the Smoothing
function, areas on the waveform with a large amount of noise can be “smoothed out”
when measured.
