® Turb 750 IR/T Operation Operation Inserting a cell Before using a cell for the first time, determine and mark the suitable measuring 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 disturbed. For the following measurements, the cell marking can just be aligned with the meter marking.
