PATH LENGTH SELECTION
3.2.1 Known Path Length Measurements
The auto path length measurement setting will firstly measure a sample using the 0.5mm path
length setting. If the measured photometric value is within range, the value will be displayed on
screen and no more measurements are taken. If however the measured value is over-range, the
sample will be re-measured using the 0.2mm path length setting.

If the required measurement path length is
known it can be selected by pressing the
button adjacent to the 0.2mm or 0.5mm
Path Length Setting icons. The selected
setting is indicated by an icon with a black
background. Once the required path length
setting has been selected press the button
adjacent to the Tick icon to confirm.
If the required measurement path length is not
known in selected modes the auto path length
setting can be selected by pressing the button
adjacent to the Auto Path Length Setting
icon. Once the auto path length setting has
been selected press the button adjacent to
the Tick icon to confirm.
