OS35
Infrared Temperature Sensor
Installation Instructions
1. Install OS35 as close as practical to view target material to be measured
2. Wire OS35 with Red to Positive Power, Black to Ground, White to Positive
Output Signal, and Green to Reference Output Signal
3. Measure actual temperature of target material with OS950 Thermometer or
any reliable reference
4. Adjust “offset”, “zero”, or “low cal” on input device to match reading to ac-
tual thermometer reading
5. Installation calibration complete
