1.2.1 Lithium powerpack –

Important information

The lithium powerpack (B) serves to save all important data (saved measurement results, settings) for approx. ½ year when the unit is not being supplied with power by the battery pack or the mains supply.

As long as the colorimeter is being supplied with mains or battery power, it does not draw any power from the lithium powerpack. Since lithium powerpacks have a very long life, it will in all probability not be necessary to exchange the one supplied. All the same, to ensure proper functioning it is recom mended to replace the lithium powerpack every five years.

Note

When neither the mains adapter nor the battery pack are supplying power, removal of the lithium powerpack will result in a complete loss of data (saved measurement results and settings). For this reason we strongly recommend that the unit is connected to the mains power supply while replacing the lithium powerpack.

1.2.2 Charging the battery pack

The rechargeable batteries (A) remain in place in the photo m eter for recharging. Once the mains power supply is established, the batteries start to be charged.

Charge the rechargeable batteries in the instrument for 5 days (working with power from mains is possible). Now use the instrument without mains until the first battery warning comes up. Charge again, 4 days this time. Repeat usage to battery warning and charging four times.

Approximately 10 charging/discharging cycles are required until the batteries reach their full capacity.

The unit can be operated with mains power supply with or without the batteries in place. For this you must attach the country-specific wall-socket adapter to the mains adapter.

Page 8

1.2.3 Using non-rechargeable batteries

In principle it is also possible to operate the unit using conventional batteries – in this case, however, they must never be used in combination with the mains adapter. The charging process would start automatically as soon as the colorimeter is connected to the mains power supply. Conventional batteries are destroyed by the charging current, resulting in severe damage to the unit. This also involves the risk of fire and explosion.

1.2.4 Using the protective caps

To protect the connection terminals on the unit from damage (e.g. corrosion) due to environmental influences such as e.g. dust or water splashes, the supplied protective caps should be attached over the connection points (D) when these are not being used.

4.3 Avoiding errors in

photometric measurements

1. The cells and lid must be cleaned thoroughly after each analy sis run to prevent errors due to cross-contamination. Even the smallest residues of reagents will lead to erroneous results.

2. The outer walls of the cells must be clean and dry before the analysis is carried out. Fingerprints or water droplets on the light-path surfaces of the cells will lead to erroneous results.

3. The cells for the zero calibration and the test itself must always be inserted into the measurement compartment in such a way that the white triangle or, respectively, the line of the graduation is correctly aligned with the corresponding mark on the case (see page 16 or 17).

4. The zero calibration and the test itself must both be made with the cell lid in place. The cell lid of the 24-mm cell must be fitted with a seal ring. The 16-mm cell must be covered with the lid for the adapter.

5. The formation of air bubbles on the inner walls of the cell will lead to erroneous results. In this case attach the cell lid to the cell and swirl the cell to eliminate any air bubbles before carrying out the test.

6. Care must be taken to prevent any water from entering the measurement compartment. Any entry of water into the case of the colorimeter may result in the destruction of electronic components and in damage due to corrosion.

7. Any contamination of the optical components in the measure ment compartment will lead to erroneous results. The light-path surfaces of the measurement compartment must be checked at regular intervals and cleaned wherever necessary. Use moist wipes and cotton-wool buds for these cleaning operations.

8. Major differences in temperature between the colorimeter and the local environment can lead to erroneous results, e.g. due to condensation on the optical components and on the cell.

9. When operating the colorimeter make sure that it is protected from direct sunlight.
