4 How to use the device
Wearing instructions
The device is worn on the left or right wrist. If a wristwatch is worn, the
DTI-2 should be worn on the other wrist. The position should as close to
the hand as possible without discomfort or hindering any hand postures.
The strap closure is at the side of the thumb. The DTI-2 is fixed to the
wrist with a flexible strap. Please pay attention to the level of tightening.
The wrist band should be fixed to the wrist, i.e. not dangling loose. The
wrist band should however be comfortable to wear and not strapped too
tight. Optimal is the loosest strap position without dangling.
Place the rubber strap on the underside of the wrist, such that the skin
conductance electrodes contact a desired area of the skin:
recommended is to center the electrode furthest from the thumb and
wrap the strap towards the electronics module.
Recommended position of the wristband sensor skin conductance
electrode for best results.
