5.3 ELECTRICAL
Rated Voltage:
DC 7V max.
Resistance X axis:
Resistance Y axis:
300 to 850 Ω (at the connector)
100 to 600 Ω (at the connector)
Switch Bounce (Chattering): 20ms min when using the silicon rubber measurement rod
Insulation resistance:
Dielectric Strength:
Linearity:
10MΩ minimum at 25KV DC
No problems when at 25KV DC for 1 minute
2% max.
Note 1:
Measurement condition of linearity is corrected within the
control IC. In general the location accuracy is specified
as follows:
Actual co-ordinate point - theoretical co-ordinate point
= location accuracy.
In general a 9 point co-ordinate calibration system is used
to adjust the micro controller accuracy. (20 point can be
used in combination with an EEPROM design).

Notes
Words are written in the notes area and the size of the word is
7.5mm x 6.75mm. A word is any Alphabet / Number / Mark.
The pen is as shown below and applies a force of 250g.
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 ±4.4 mm max.
