Function
Stored programs are pre-programmed methods that make use of HACH chemicals and
HACH-LANGE pipette tests.
On the CD for the DR 6000 you find illustrated, step-by-step procedure instructions for
analyses with HACH programs. The working procedures for HACH-LANGE tests are included
in the test packs.
User programs make "made to measure analysis" possible:
• Users can program methods they have developed themselves
• Existing HACH- and HACH-LANGE procedures can be stored as user programs.
These procedures can then be modified according to separate requirements.
List of methods/tests created by the user to suit his own requirements.
Single wavelength readings are:
Absorbance readings: The light absorbed by the sample is measured in absorbance units.
Transmittance reading (%): Measures the percent of the original light that passes through the
sample and reaches the detector.
Concentration readings: A concentration factor can be entered to enable the measured
absorbance values to be converted into concentration values.
In the Multi Wavelength mode, absorbance (Abs) or percentage 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.
A wavelength scan shows how the light from a sample is absorbed over a defined wavelength
spectrum. This function can be used to determine the wavelength at which the maximum
absorbance value can be measured. The absorbance behavior is displayed graphically during
the scan.
The time scan records the absorbance or % transmittance at a wavelength over a defined
time.
The "System check" menu offers a number of options, including optical checks, output checks,
lamp history, instrument update, service time, settings for analytical quality assurance and
instrument backup.
Stored data can be called up, filtered, sent and deleted.
In this mode, user-specific or method-specific settings can be entered: operator ID, sample ID,
date & time, sound, PC & printer, password, energy-saving mode and stored data.
