STORED PROGRAMS /
BARCODE PROGRAMS
Stored programs are pre-programmed methods that make use of reagents, cell tests, and
pipette tests.
Refer to the DR 2800 Procedure Manual for step-by-step procedures for analyses using stored
programs.
USER PROGRAMS
User programs make "made to measure analysis" possible:
Users can program methods they have developed themselves
Stored methods can be saved as user programs. The tests can then be modified to suit the user's
requirements.
FAVORITE PROGRAMS List of frequently-used methods/tests selected by the user.
SINGLE WAVELENGTH
Single wavelength measurements are:
Absorbance measurements: The light absorbed by the sample is measured in absorbance units.
Transmittance measurements (%): The percentage of the light that passes through the sample and
reaches the detector is measured.
Concentration measurements: A concentration factor can be entered to enable the measured
absorbance values to be converted into concentration values.
MULTI-WAVELENGTH
In the multi-wavelength mode, absorbance (Abs) or percent transmittance (%T) is measured at up to
four wavelengths, and absorbance differences and absorbance relationships are calculated. Simple
conversions into concentrations can also be carried out.
TIME COURSE The time scan records the absorbance or % transmittance at a wavelength over a defined time.
SYSTEM CHECKS
The system checks menu offers a number of options, including optical checks, output checks, lamp
history and instrument update.
RECALL DATA Stored data can be called up, filtered, transmitted and deleted.
INSTRUMENT SETUP
In this mode, user-specific or method-specific settings can be entered: Operator-ID, Sample-ID, Date
& Time, Display & Sound, Power Management, PC & Printer and Password.
