The Trigger Setup display shows the trigger settings in an
interpretive way. Only applicable settings are displayed.
The interpretation of the Trigger Setup display is as follows:
• The 824 will arm when the 1 kHz filter is greater than
80.0 dB for a period of 1 second.
• When the level of the 1 kHz filter drops below 80.0 dB
for 0 seconds (immediately), the 824 is triggered and
begins taking a measurement.
Pressing the
c
Check key provides
quick access to the trigger settings.
• The measurement continues until the End condition is
met which means that the level must drop below 50 dB
for 2 seconds.
