Instructions
6. SENSOR MAINTENANCE
The CS800-L should be visually inspected every
1 - 3 months, depending on site conditions and
the desired accuracy. Damaged cupsets and
vanes should be replaced. Bearings in the
anemometer and vane should be replaced on a
periodic basis, or when measured starting
torque exceeds predetermined thresholds.
A suggested maintenance schedule is as
follows:
1 month:
• Visually inspect the cupwheel and vane
assemblies for damage.
• Do a visual/audio inspection of the
anemometer at low speeds. Make sure the
cupwheel assembly rotates freely, without
any wobble. Worn bearings will often
produce an audible noise.
