Page 7: Floor Sensor Testing
Floor Sensor Testing A good-quality test meter capable of measuring up to 5,000 kΩ (1 kΩ = 1000Ω) is required to measure the sensor resistance. In addition, measure the actual temperature with either a good-quality digital thermometer, or if a thermometer is not available, place a second sensor alongside the one to be tested and compare the readings. - Page 8 Temperature vs. Resistance Table - Continued Temperature Resistance Temperature Resistance °F °C °F °C 5,828 1,538 5,210 1,403 4,665 1,281 4,184 1,172 3,760 1,073 3,383 3,050 2,754 2,490 2,255 2,045 1,857 1,689 www.uponorpro.com...
