8.2 Accessing Trillium Compact Web pages
Proceed as follows to access the Trillium Compact Web pages through the Centaur digitizer:
You can connect two sensors to the 6-channel Centaur. Each sensor is accessed from
one of the Serial radio buttons.
1. Login to the Centaur.
2. Navigate to the
Sensors
page.
3. For each seismometer,
a. If the Discovery section of the Sensors page indicates “No sensor found”, click on
the
Discover
button.
b. Click on the
Serial
radio button (
A
or
B
). A link to the sensor Web home page will
display.
c. Click on the link located above the
Discover
button to access the Trillium
Compact Web pages.
8.3 Viewing the Current State-of-Health
The
SOH
page provides detailed information that indicates the health and status of the
seismometer, including the following:
l
Temperature.
Displays the approximate temperature of the Trillium Compact
seismometer in Celsius and Fahrenheit.
l
Case tilt angle.
Displays the tilt of the case from vertical in degrees.
The case tilt feature applies to all Trillium Compact models with serial numbers 2500
and above.
l
Mass Positions (Range ±4)
The mass position values for the U, V, and W axes for the
seismometer module. These values range from 0 V (perfectly centered) to
approximately ±4 V (when decentered and not able to respond to ground motion). The
mass position output on pin R of the connector is an analog voltage that corresponds
to the axis that is decentered the most. For example, if the U, V, and W mass positions
are +0.230 V, -2.200 V, and +1.024 V respectively, then the analog mass position
