Example 3 (Plaster):
Suppose that selected trigger level is 0.50 in/s, which is equal to the
nominal level for Plaster. A transient will be triggered if a signal (peak) is
larger than:
• 0.38 in/s, if its frequency is 2 Hz
• 0.5 in/s, if its frequency is in the range 2.6 - 1 Hz
• 2.0 in/s, if its frequency is larger than 40 Hz
Example 4 (Plaster):
Suppose now that selected trigger level is increased to 1.0 in/s compared
to Example 3. A transient will be triggered if a signal (peak) is larger than:
• 0.76 in/s, if its frequency is 2 Hz
• 1.0 in/s, if its frequency is in the range 2.6 - 10 Hz
• 4.0 in/s, if its frequency is larger than 40 Hz
As can be seen, all three figures above are doubled compared to the
values in Example 3. [
