OSSD Response Times
The total response time of your application is dependent on:
• The basic response time of the SafeZone Mini device.
• The multiple sampling set.
• The OSSDs that are used.

Multiple Sampling
On the SafeZone Mini device at least double multiple sampling is always set.
For a multiple sampling of three or higher, you must add a supplement of 80 ms
to the basic response time.
