Table 5.4 Setups Block Summary
Typical values: For most touch applicatio ns, use the values shown in the outlined cells. Bold text items indicate default settings. The number to send to the QT is the number in
the leftmost column (0..15), not numbers from the table. The QT uses a lookup table internally to translate 0..15 to the parameters for each function.
NRD is an exception: It can range from 0..254 which is translated from 1= 0.5s to 254= 127s with zero = infinity.
