a. Sensor Check:
Use the Sensor Check feature to determine if the attached sensors are connected,
oriented, and working properly, or to ensure that the sensors match the current settings
within the
View/Edit Setup File menu if it has been set to Before or After an Event.
The results of the Sensor Check and the associated information for each sensor,
including Serial Number , Calibration Date , and Calibration Location , appear on the
Event Report .
A
Sensor Check may be setup to occur automatically, or by manual key-press:
(1) Repeatedly press the Right Arrow key to set when a Sensor Check will occur,
After Event or Before Event . You can also select Disable . If you select
Disable , a Sensor Check can still be performed manually by pressing the
Sensor Check key on the monitor. The manual Sensor Check is only allowed
when the unit is not in monitor mode.
If
Sensor Check is set Before Event , the check is performed once and added to
all subsequent Event data. If the Sensor Check is set to After Event , then the
Sensor Check is performed after each Event and added to each Events data.
(2) Press Enter key to Save any changes, or the Cancel key to return to the
Preferences menu, or
(3) Press the Sensor Check key to perform a manual check while at the main menu.
NOTE: The Sensor Check is not a calibration check and cannot replace the annual
calibration process. Sensor Check does not compare the measured result against an
external traceable reference sensor, nor does it test the entire electronic circuit that
is integral to the sensors response.
NOTE: The sensors selected within the Edit Current Setup menu should match what is
attached to the unit.
Example: If the Pressure Sensor Channel is Off and a Linear Microphone is
attached, or if it is On , and a Linear Microphone is not attached, the Sensor
Check will return the message, “ Sensor Detection Error – Attached Sensors do
not match setup
”.
When a Sensor Check error occurs, check the following for possible causes:
o
Was the sensor moved during the Sensor Check ? This will result in a
failed reading.
o
Ensure that the orientation of the Geophone is correct, as per the given
application, such as a ceiling installation. Refer to the section in this manual,
Geophone Direct Hard Surface Mount Installation Instruction.
