6.2.3 Routine Instrument Care Instructions
All equipment requiring routine maintenance should be identified and maintenance
instructions provided in the manual. Routine maintenance tasks can be divided into
two categories: those related to the tower structure, supports, and grounding, and those
related to the instruments and data acquisition system. The following sections lists the
tasks typically performed in each category.
Tower Structure, Supports, and Grounding
1.
Anchor Condition
•
Check for signs of rust or damage.
•
Assess movement of the anchors over time.
•
Verify the integrity of the anchor connections; for example, the anchor resis-
tance may have changed if an animal has burrowed near the connection point.
2.
Guy Wire Condition
•
Check that the guy wires are properly tensioned in accordance with the man-
ufacturer's guidelines. Tension the guy wires if necessary.
•
Inspect the wires and connection points for signs of rust or corrosion.
•
Ensure that the appropriate number of wire clips were used to secure the wires
and that the clips are in good condition.
3.
Tower Condition
•
Check for signs of rust or damage.
•
Confirm that the tower is plumb and straight.
•
For tubular towers, examine the tower for signs of flaring at the connection
points between tower sections.
Inspect the baseplate or foundation to ensure that it is not sinking or distorted
and is otherwise free from damage.
•
4.
Grounding System
•
Verify that the grounding system is connected properly and the electrical
contacts are in good condition.
Instruments and Data Acquisition System
1.
Sensors
•
Inspect the sensor booms and instrument pillars to make sure they are level
or plumb and in good condition.
•
Booms are known to slip or rotate; confirm that all booms are at the correct
heights and point in the correct directions.
•
Replace any sensors that data analysis shows may be deteriorating or may
have failed (Chapter 9).
