Page 7: Section 1 - Introduction
SECTION 1 - INTRODUCTION Instrument Description The Model 6051 is a general purpose laboratory colorimeter housed in a custom designed case. The visible spectrum is covered by eight gelatin filters incorporated within the unit. Optional interference filters are available to enable other visible wavelengths to be obtained, results are displayed in either %Transmittance, Absorbance or Concentration units via a 17mm L.C.D. readout. Samples may be presented to the 6051 in 10mm square cuvettes of standard or semi-micro volumes, test-tubes or Pour-in/Suck-out cells. An analogue output of 1mV per digit is available on the rear panel. -
Page 8: Section 2 - Installation
SECTION 2 - INSTALLATION Unpacking Remove the Model 6051 from the packaging and ensure the following items are present: 1. 6051 Colorimeter 2. Mains Cable 3. Pack 100 Disposable Plastic Cuvettes 4. Test Cuvette Installation Mains Supply The 6051 is designed to operate on 230 or 115V a.c. supplies (± 15%) 50/60Hz. The power consumption is 20W. The standard 2 metre mains lead supplied with the unit is fitted with an IEC type connector which can be plugged directly into the Power In socket on the rear panel. Fuse ratings: 230V = 250mA (Anti-surge) 115V = 500mA (Anti-surge) NOTE: The unit should be positioned within 1.5 metres of an earthed mains supply. -
Page 9: Displays/Controls
Displays/Controls Fig. 2.3.1 Front Panel Displays and Controls 1. Wavelength Select - Thumbwheel used to select the correct wavelength for the specific tests being performed. 2. Main display - 2½ Digit LCD. 3. Blank Control - This control is used when standardising the unit. Normal practice is to set the Abs or %T value with a cuvette of deionised water. The Blank control is then set to give the correct reading. 4. Concentration - This control is used when the mode switch is in the Conc 1 and 2 positions. These ranges are extensions of the Absorbance mode, allowing the reading obtained to be set to a value convenient to the standard concentration. 5. -
Page 10: Inputs/Outputs
Conc - (Concentration Ranges) - These ranges are extensions of the absorbance mode, allowing the reading to be set to a value convenient to the reference solution concentration. The reading may be increased or decreased by up to a factor of ten. 6. Sample Area - Samples may be presented in 10 x 10mm cuvettes of standard or semi-micro volumes or test tubes. 7. Sample Area Lid - The lid should be kept closed, when necessary to eliminate the possibility of erroneous results caused by the ingress of stray light. For many determinations, the lid may be left open. Inputs/Outputs Fig. 2.4.1 Rear Panel Layout 1. Zero - A preset control which should rarely require adjustment and is provided to offset photocell dark current. 2. Jack Socket - Connection socket for the external 12V d.c. supply. 3. 4mm Pin Sockets - An analogue voltage of 10mV per digit is available on these sockets. 4. -
Page 11: Section 3 - Operation
Initial Set-Up 1. Connect the unit to the mains supply and switch on. Select %T by use of the Function Switch. Allow 15 minutes warm-up period at this point to ensure the optical and electronic systems have sufficient time to stabilise. 2. Insert the test cuvette (black cuvette supplied with the unit) into the sample chamber. The wavelength reading is not critical at this point. The display should read zero. Adjustment to this reading can be made by use of the Dark Current Offset control located on the rear panel. If adjustment is required the blank and zero settings should be re-checked until they are both correct. 3. Remove the test cuvette from the sample chamber. 4. Fill a cuvette to within 1cm of the top with distilled or deionised water and place in the sample chamber. Close the sample chamber lid. Select the required wavelength or interference filter. Set the display to read 100 using the Blank Control. The reading should be stable. 5. Remove the cuvette from the unit. The 6051 is now ready for use. NOTE: During sample measurement the sample area lid should ideally be kept in the closed position to eliminate the possibility of erroneous results caused by the ingress of stray light. For many determinations, however, the lid may be left open without causing significant errors. Sample Measurement 1. Allow 15-minute Warm-Up prior to use refer to 3.1 Initial Set-Up. 2. Select the required filter position for maximum absorbance. If this is not known, the colour complimentary to that of the standard solution can be selected from the list given below. The chart may be read from left to right or right to left, i.e. a blue sample requires a yellow filter / a yellow sample requires a blue filter. Blue - Yellow Bluish/Green... -

6. The unit is now ready for operation in the Absorbance mode. 7. Operation in the %Transmittance mode can be performed by selecting %T using the Function switch. The unit will now read directly in %T and the blank sample should read 100 %T. 8. Operation in the Concentration mode can be performed by selecting either Conc 1 or 2 using the Function Switch. The standard value should be set to a convenient reading using the Concentration Control. The unit will now read directly in sample concentration. NOTE: To ensure optimum performance refer to Section 3.3 Good Practice Guidelines. 9. When using separate interference filters set the filter wheel to one of the “F” positions. Remove the blanking filter from the filter compartment and insert the interference filter to be used. The “F” positions have varying degrees of light attenuation to cater for the wide spread of transmission characteristics encountered with interference filters. The degree of attenuation varies from zero on position F1 through to a maximum on F4. In most normal circumstances position F1 will be most appropriate. If, however, lower than expected absorbance values are obtained, it is probable that the detector circuit is saturating and a range with more attenuation should be selected. The unit is now ready for use. -
Page 13: Section 4 - Maintenance, Servicing And Repair
SECTION 4 - MAINTENANCE, SERVICING AND REPAIR WARNING: Ensure the unit is disconnected from the mains electricity supply before attempting maintenance or servicing. Maintenance The 6051 has been designed to give optimum performance with minimum maintenance. The only maintenance required is to clean the external surfaces with a damp cloth and mild detergent and keep free from dust. To give added protection when not in use the unit should be disconnected from the mains supply and covered with the optional dust cover. For longer term storage or re-shipment, it is recommended that the unit be returned to the original packing case. Light Source Replacement The only routine maintenance which may be required is the replacement of the light source due to failure. Failure should be suspected if the reading remains at zero in %T mode or reads overrange in Abs or Conc modes. This can be confirmed by considering the cuvette chamber. -
