Stored Programs / | Stored programs are | |
Barcode Programs | cuvette tests and pipette tests. | |
(HACH LANGE | The DR 2800 Procedures Manual contains illustrated, | |
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. | |

| |
| 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 | 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. | ||
