Turb 430 IR/T Operation Venting the sample Avoiding or removing air bubbles 4.5 Turbidity 4.5.1 General information Air bubbles in the sample affect the measuring result to a massive extent because they have a large scattering effect on the incident light. Larger air bubbles cause sudden changes in the measured values whereas smaller air bubbles are recorded by the instrument as turbidity.
Operation Turb 430 IR/T 4 Marking a cell Release the key. Measurement starts. The measured value is displayed. To be able to quickly bring a cell into the optimum position, it is helpful to mark the optimum position of the cell once it is determined.

Turb 430 IR/T Appendix: Firmware update General information With the "Firmware Update Turb430" program you can update the firmware of the Turb 430 IR/T to the latest version with the aid of a Personal Computer. A free serial interface (COM port) on your PC and an interface cable is required for this (see chapter 8 ACCESSORIES, OPTIONS). Program installation Program start Install the firmware update program on your PC with the "Turb430_Vx_yy_English.exe" installation program.
Turb 430 IR/T Appendix: Turbidity values under 1 FNU/NTU With turbidity values (under 1 FNU/NTU), the measured value is strongly influenced by the cell and its alignment. In order to increase measuring accuracy with turbidity values under 1 FNU/NTU, calibration in the 0.02 FNU/NTU standard and later measurement should be carried out in the same cell. For calibration in the standards 10.0 and 1000 FNU/NTU follow the instructions on the display.
