Adjustment Of The Arms; Operation - Observator Instruments Diff-Automatic User Manual

2.3.2 Adjustment of the arms

It is possible to adjust the arms of the Diff by pushing both grey buttons at the same time. The arms will
"click" every 30˚. This makes it possible to set a comfortable position for every situation. The display unit
can be rotated to ensure an optimal reading during the measurement.
Make sure that the display of the DIFF is not placed in front of the round opening! Putting the
display in the air flow will cause faulty measurements. All measured values will be out of
specifications.
These pictures show the right position of the arms and the display.

2.3.3 Operation

The DIFF can be operated with only one button. The readings are shown on the display.
The DIFF can be switched on by pushing in the middle of the scroll button. The recess in the scroll button
is intended for scrolling through the menu.
