(4) Photometric values can also be displayed on the LCD.
(5) Graphic display on the LCD can be output onto the printer. It takes a little
over 10 seconds to make a hard copy for the graphic display on the LCD.
2.4.3 Time Scan
(1) A graph can be displayed with time graduated on the abscissa.
(2) Photometric values can be printed out at the specified time interval.
(3) Data can be calculated for right assay.
2.4.4 Secondary Processing Functions
The HALO DB-20 can store in the memory the measured spectrum and its
change with time.
Secondary processing can be applied variously to the stored data.
Automatic Data Readout
A cursor can be moved to a desired point in the spectrum currently
displayed on the LCD screen and a reading of the absorbance (transmittance)
at that point.
Peak Detection
Cursor can be moved to a peak position to display absorbance
(transmittance) readings at the peak. In addition, an automatic peak
selection routine allows peak and valley measurements to be printed in list
format on the printer.
Scale Expansion
Three methods are available for expanding the graphic display on the LCD.
(a) Simultaneous Expansion of X and Y Axes
Cursor should be moved for pointing out a desired expansion range.
(b) Expansion of X Axis
Numeric values should be input to specify a desired expansion range
for the abscissa.
