Page 3: Certificate Of Compliance
RoHS 3 compliant using exemption 6c. Further note that Apogee Instruments does not specifically run any analysis on our raw materials or end products for the presence of these substances, but rely on the information provided to us by our material suppliers. -
Page 4: Introduction
The curved inlet helps draw air into the shield during high cross winds. These unique properties make the TS-100 ideal for use in remote locations with limited power supply. -

*If the Rotronic HC2-S3 probe is used with the E3 Active Set module, it must be water-proofed before use with the Apogee TS-100 radiation shield. The E3 Active Set module is not water proof (water can infiltrate at the point where the cable enters the housing). -

, the mean of the model TS-100 shields has been within 0.05 C of the means of the other two models of shields. At higher wind speeds, the TS-100 and R. M. Young shields read slightly cooler (-0.05 C) than the mean of the Met One shields, but the difference is not... - Page 7 *IP55 The fan inside the TS-100 is extremely well sealed against water and dust, with an ingress protection (IP) rating of 55, called IP55. Higher numbers indicate better protection. Fans typically range from IP11 to IP55. The first digit in the IP rating indicates protection against particle entry.

Page 9: Deployment And Installation
DEPLOYMENT AND INSTALLATION TS-100 fan-aspirated radiation shields come partially pre-assembled and has few parts, facilitating easy transport, deployment, and maintenance. Avoid placing the shield near buildings, paved surfaces, or any other locations which may create a micro- environment significantly different than ambient environment. The World Meteorological Organization (WMO) recommends a mounting height of 1.25 to 2 meters above ground. -
Page 10: Cable Connectors
CABLE CONNECTORS Apogee started offering in-line cable connectors on some bare-lead sensors in March 2018 to simplify the process of removing sensors from weather stations for calibration (the entire cable does not have to be removed from the station and shipped with the sensor). The ruggedized M8 connectors are rated IP68, made of corrosion-resistant marine-grade stainless-steel, and designed for extended use in harsh environmental... -
Page 11: Operation And Measurement
OPERATION AND MEASUREMENT Connect the temperature sensor or RH probe sensor to a measurement device (meter, datalogger, controller). If you are using the ST-110, this device must be capable of inputting 2.5 V DC, and measuring and displaying or recording a millivolt (mV) signal (an input measurement range of 0-2500 mV is required to cover the entire temperature range of the ST-110 air temperature sensor). - Page 12 An excitation voltage of 2.5 V DC is recommended to minimize self-heating and current drain, while still maintaining adequate measurement sensitivity (mV output from thermistor per C). However, other excitation voltages can be used. Decreasing the excitation voltage will decrease self-heating and current drain, but will also decrease thermistor measurement sensitivity.
- Page 13 Conversion of Thermistor Resistance to Temperature The thermistor is a resistive element, where resistance changes with temperature. Thermistor resistance (R , in Ω) is measured with a half-bridge measurement, requiring a known excitation voltage input (V ) and a measurement of output voltage (V ...

Page 14: Maintenance And Recalibration
MAINTENANCE AND RECALIBRATION At full duty, the fan is designed to last 50,000 hours (5.7 years). Ultimately, this depends on operating conditions, and actual results may vary. If the fan runs less than approximately 4500 RPM at full power, then there may be a blockage or the fan may need to be replaced. -
Page 15: Troubleshooting And Customer Support
TROUBLESHOOTING AND CUSTOMER SUPPORT Independent Verification of Functionality Apogee ST-110 temperature sensors yield a resistance proportional to temperature. A quick and easy check of sensor functionality can be accomplished with an ohmmeter. Connect the lead wires of the ohmmeter to the red and white wires from the sensor. - Page 16 1 mega-ohm or higher then there is negligible effect on the sensors, even after adding up to 100 m of cable. TS-100 aspirated radiation shields use shielded, twisted pair cable, which minimizes electromagnetic interference. This is particularly important for long lead lengths in electromagnetically noisy environments.

Page 17: Return And Warranty Policy
RETURN AND WARRANTY POLICY RETURN POLICY Apogee Instruments will accept returns within 30 days of purchase as long as the product is in new condition (to be determined by Apogee). Returns are subject to a 10 % restocking fee. WARRANTY POLICY... - Page 18 84321, USA 5. Upon receipt, Apogee Instruments will determine the cause of failure. If the product is found to be defective in terms of operation to the published specifications due to a failure of product materials or craftsmanship, Apogee Instruments will repair or replace the items free of charge.
