5.1.3 Main Menu

A variety of modes may be selected from the ”Main Menu“. The following table briefly describes each menu option.

	Table 2 ”Main Menu“ Options DR 2800
Option	Function
Stored Programs /	Stored programs are pre-programmed methods that make use of HACH reagents and LANGE
Barcode Programs	cuvette tests and pipette tests.
(HACH LANGE	The DR 2800 Procedures Manual contains illustrated, step-by-step procedures for analyzes
Programs)	using HACH programs. The working procedures for LANGE tests are included in the test packs.
	User programs make "made to measure analysis" possible:
User Programs	- Users can program methods they have developed themselves
	- Existing HACH and LANGE methods can be stored as user programs. The LANGE tests can
	then be modified to suit the user's requirements.
Favorite Programs	List of methods/tests created by the user to suit his own requirements.
	Single wavelength measurements are:
	Absorbance measurements: The light absorbed by the sample is measured in absorbance
	units.
Single Wavelength	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.
	In the multi-wavelength mode, absorbance (Abs) or percentage transmittance (%T) is measured
Multi Wavelength	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, instrument update, service time and instrument backup.
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.
