example, the seismograph may be set to trigger and record an event at the standard level.
A second level could be used to activate a strobe and a third level could be used to activate
a horn.

Sensor
Different levels can be applied to channels 1-4 and channels 5-8. Sensor 1 represents
channels 1-4. Sensor 2 represents channels 5-8.
Units and Levels
Lv 1 (level 1) is the first optional level. In the above example it will fire at 0.25 ips or 130 dB.
Lv 2 (level 2) is the second optional level. It is set to fire at 0.50 ips or 140 dB.
Main Screen Trigger
If the operating mode is set to waveform or histogram/waveform, the trigger can be set to
Armed or Disarmed. If the field is set to Disarmed, the instrument will not trigger.
At power on, the trigger will be set to Disarmed. However, if the display is allowed to
power down, the trigger will arm. This feature means that, when in Waveform Mode, the
instrument can be powered on and will automatically arm itself after approximately one
minute. Also, if for some reason a remote unit would reset, it would automatically rearm.
Please note that the instrument cannot be powered off while the trigger is armed or while a
histogram is active, unless a forced power off is used.
Main Screen Data Port
The Data Port specifies what will be used for communication. The choices are RS232 and
USB. The RS232 selection means that serial communication will be used which is the female
