No field calibration is necessary or recommended. TROUBLESHOOTING SymptomSolution No output Check wiring. Ensure power supply meets requirements. Temp or RH reading error Verify control panel software is configured for correct output scaling. Verify accuracy of test instrument. Observe installation guidelines Verify unit is located away from sources of hot/ cold. Install insulation foam gasket provided to prevent thermal conduction from inside wall. COMPUTER ROOM OUTSIDE WALL OR WINDOW TOO HOT/COLD INSIDE WALL TOO HOT/COLD COPIER TOO NEAR EQUIPMENT OR DOORWAY GOOD LOCATION GOOD LOCATION GOOD LOCATION 3. If installing in a junction box, check that provided insulation covers entire junction box opening to ensure reading accuracy. 4. Snap on screw covers to complete installation. PRODUCT APPLICATION LIMITATION: Senva products are not designed for life or safety applications. Senva products are not intended for use in critical applications such as nuclear facilities, human implantable device or life support. Senva is not liable, in whole or in part, for any claims or damages arising from such uses. INSTALLATION 1. IMPORTANT! Locate sensor in an area away from ventilation sources and heat generating equipment and appliances. Sensor should be mounted at light switch height in a vertical orientation. NOTE: Do not install sensor in multi-gang electrical boxes with line voltage or other electrical devices. 2.
