Operating The Capacitive Single-Touch Screen - Siemens SIMATIC TP700 Comfort INOX PCT Operating Instructions Manual

2.7

Operating the capacitive single-touch screen

The capacitive touch screen of the HMI device differs fundamentally in its behavior from a
resistive touch screen, for example:
• The touch screen reacts to contact on its surface, not to pressure.
• The touch screen is operated with the fingertips.
• The finger can be surrounded by thin material, for example, protected by a sterile glove.
• The touch screen is optimized for robust operability, even with a light film of moisture.
• Operation with a touch pen is not recommended.
NOTICE
Damage to the touch screen
Improper operation can damage the touch screen.
• Never touch the touch screen with pointed or sharp objects.
• Do not operate the touch screen with tools, for example a screwdriver.
• Do not operate the touch screen with chain gloves.
• Avoid impact with hard objects on the touch screen.
This can substantially reduce the useful life of the touch screen and even lead to total
failure.
