3.4.3 Pen Life
Note taking life (Pen Life) : 100,000 words minimum
Input life (Finger Life) : 2,000,000 times minimum
Note:
Words are written in the notes area and the size of the word is
7.5mm x 6.75mm. A word is any combination of alphabet characters,
numbers, or marks.
The pen is as shown below and applies a force of 350g.
A failure is judged to happen when the current consumption or
insulation resistance or dielectric strength are not met as shown
in 5.3. The location accuracy with 9 point calibration must be
±4.4mm max.
3.4.4 Finger Life
A finger is simulated by a silicon rubber plunger R8 (round type 8mm size), with a hardness of 70
℃
at 200g and
at a frequency of 5Hz.
A failure is judged to happen when the current consumption or insulation resistance or dielectric strength are
not met. The location accuracy with 9 point calibration must be +4.4mm max. Operating force is 150g max.
