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.
