Model 18802 Anemometer Drive provides a convenient and accurate way to rotate an anemometer shaft at
a known rate. The motor may be set to rotate clockwise or counter-clockwise at any rate between 200 and
15,000 RPM in 100 RPM increments. The LCD display is referenced to an accurate and stable quartz timebase.
For completely portable operation, the unit can be operated on internal batteries. For extended operation, an
AC wall adapter is included.

Model 18811 Anemometer Drive is identical to Model 18802 except the drive motor incorporates a
gear reducer for operation in the range of 20 to 990 RPM in 10 RPM increments. The lower range
is recommended for cup anemometer calibration.

Model 18112 Vane Angle Bench Stand is used for benchtop wind direction calibration of the Wind Monitor
family of sensors. The mounting post engages the direction orientation notch on the Wind Monitor. An easy to
read pointer indicates 0 to 360 degrees with 1/2 degree resolution.

Model 18212 Vane Angle Fixture - Tower Mount similar to the Model 18112, the tower mount feature allows use
on the tower as well as the bench top. The fixture is temporarily placed on the tower between the Wind Monitor
and its tower mounting. Index keys and notches are engaged to preserve direction reference.

Model 18310 Propeller Torque Disc checks anemometer bearing torque with 0.1 gm/cm resolu-
tion. The disc temporarily replaces the propeller for torque measurement or simple yet accurate pass/fail
checks. Charts included with the unit relate torque to propeller threshold with limits for acceptable
bearing performance.

Model 18312 Cup-Wheel Torque Disc checks cup anemometer bearing torque.

Model 18331 Vane Torque Gauge checks vane bearing torque of the Wind Monitor family sensors. Slip the
fixture over the main housing and make simple yet accurate vane torque measurements. Charts relating vane
torque to vane threshold provide limits for acceptable bearing performance.

Model 18301 Vane Alignment Rod helps align the vane of a wind sensor to a known direction reference during
installation. The base of the device has an index key that engages the direction orientation notch in the sensor
allowing the sensor to be removed without losing wind direction reference.
