Table 2 Main Menu options

Option	Function
Stored Programs/Barcode Programs (HACH-LANGE programs)	Stored programs are pre-programmed methods that make use of HACH chemicals and HACH-LANGE pipette tests. The working procedures for HACH-LANGE tests are included in the test packs. Further information, as well as illustrated, step-by-step process instructions for analyses using HACH programs, are available on the website of the manufacturer.
User Programs	User programs make "made to measure analysis" possible: Users can program methods they have developed themselves Existing HACH and LANGE methods can be stored as user programs. The HACH-LANGE tests can then be modified to suit the user's requirements.
Favorites	List of methods/tests created by the user to suit his own requirements.
Single Wavelength	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.
Multi Wavelength	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.
Wavelength Scan	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.
Time course	The time scan records the absorbance or % transmittance at a wavelength over a defined time.
System checks	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.
Recall measurement data	Stored data can be called up, filtered, sent and deleted.
Instrument Setup	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.

Save, recall, send and delete data
