Page 9: Operation
® Turb 750 IR/T Operation Operation Inserting a cell Before using a cell for the first time, determine and mark the suitable measur- ing position for the cell (see P , page 9). REPARING THE CELL Push the dust cover (1) upward. The cell shaft for 28 mm cells is open. - Page 10 ® Operation Turb 750 IR/T Prior to using a cell for the first time, the suitable position of the cell in the cell shaft is determined and marked to make sure the optical path is not dis- turbed. For the following measurements, the cell marking can just be aligned with the meter marking.
