METEOROLOGICAL INSTRUMENTS INSTRUCTIONS WIND MONITOR WITH 4-20 mA OUTPUTS MODEL 05103L R.M. YOUNG COMPANY 2801 AERO PARK DRIVE, TRAVERSE CITY, MICHIGAN 49686, USA TEL: (231) 946-3980 FAX: (231) 946-4772 WEB: www.youngusa.
INTRODUCTION MODEL 05103L The 05103L Wind Monitor measures wind speed and direction and provides calibrated wind speed and direction signals via independent loop-powered 4-20 mA analog transmitters. Sensor housing, nose cone, propeller, and other components use molded UV-stabilized plastic for strength, corrosion resistance, light weight, and fast response. Both the propeller and vertical shafts use stainless steel precision grade ball bearings.
e) Tighten mounting post band clamp. f) Engage orientation ring indexing pin in notch at instrument base. g) Tighten orientation ring band clamp. CALIBRATION The 05103L Wind Monitor is fully calibrated before shipment and requires no additional adjustment. Check sensor calibration once per year or as needed. Please see the wiring diagram for output scaling information. Calibration checks can be easily performed in the field using the calibration accessories available from YOUNG.
FLANGE BEARING REPLACEMENT WARRANTY If anemometer bearings become noisy or wind speed threshold increases above an acceptable level, bearings may need replacement. Check anemometer bearing condition using a Model 18310 Propeller Torque Disc. If necessary, bearings are replaced as follows. This product is warranted to be free of defects in materials and construction for a period of 12 months from date of initial purchase. Liability is limited to repair or replacement of defective item.

YOUNG Calibration Accessories 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.
