Page 9: Operation
SECTION 3 3.1 INITIAL SET-UP NOTE: If the unit is in continuous use it is recommended that it should be left switched on to obtain maximum lamp life. Do not open the sample chamber door during initialisation. Connect the unit to the correct mains supply and switch on. After switch on, the Model 6300 automatically re-aligns the monochromator at zero order wavelength. - Page 10 The complimentary colour method of selecting wavelength may not be applicable in all situations, perhaps because the solution has no distinct colour, or the solution is of a complex nature and the absorbing species of interest is not the predominant colour. In these circumstances it will be necessary to scan across the spectrum to determine points of maximum absorbance.
- Page 11 Concentration Mode This mode is selected by moving the cursor to the CONC menu option using the LEFT or RIGHT arrow keys. The primary display will show the concentration, with ppm, mgl , gl , M, % or blank units. The wavelength can be adjusted using the UP and DOWN arrow keys.

SECTION 4 4.1 GENERAL The 6300 has been designed to give optimum performance with minimum maintenance. It is only necessary to keep the external surfaces clean and free from dust. The sample area should always be kept clean and any accidental spillage should be wiped away immediately. To give added protection when not in use, the unit should be disconnected from the mains supply and covered with the optional dust cover (630 028). - Page 14 Fig. 4.2.1 Lamp Fitting Close the lamp access panel and re-tighten the thumbscrew. NOTE: It is essential that only the specified replacement lamp should be used. Accuracy of optical alignment and performance cannot be guaranteed using alternative manufactured lamps. SECTION 5 5.1 OPTIONAL ACCESSORIES The following list of items are available as optional accessories for use with the Model 6300: 630 005...
