1. Overloaded circuit breaker Scan large electrical panels in seconds to find potential faults that generate heat, such as loose connections, imbalance or overloading. Notice how the visual IR thermometer not only shows an apparent hot spot on a breaker, but the digital image also shows the exact location where the potential problem lies. Heat map overlay Full digital 2. Overheated motor output This image reflects a motor that may be overheated based on the center point measurement of 54.8 °C.

4. Potentially faulty cold air damper Use your visual IR thermometer to see how well the VAV box is working by scanning vents. The warm area in this otherwise cold vent could indicate a faulty cold air damper. Heat map overlay Full digital 5. Uneven distribution in AC condenser In this typical AC condenser, the uneven distribution of heat in the center row may indicate a potential issue. Heat map overlay Full digital 6.

7. Non-operational AC compressor The compressors in these images are running on a 4-stage system. The second stage compressor appeared cold, while the other three compressors in the system all appeared hot. This compressor will need to be further investigated. Stage 2 Compressor One of the Operational Stages 8. Thermal inspection of combination starter Use a Fluke Visual IR Thermometer to look for connection or overload conditions in combination starters.

10. Unbalanced load in three phase supply Quickly identify apparent unbalanced loadings. In this image, the fuses are connected to a water heater, and the most likely scenario is that the two fuses on the left are being used more than the fuse on the right. This could indicate a problem with the heating element in the water heater. If this were single phasing, it could indicate that the fuse on the right may be blown. The next step is to check continuity of the fuse and current loads on the 3 phases.

13. Environmental monitoring of fan for high-powered equipment If a fan starts to seize up, workers in the area may not notice until there is a burning smell. However, a quick scan with the blended thermal heat map reveals the hot and cold areas to help determine if the fans are functioning as expected. Heat map overlay Full digital 14. Troubleshoot issues with radiant flooring This radiant flooring was scanned to check for the expected heat pattern.

Set yourself up for success Follow a few simple steps that will help you troubleshoot issues in facilities applications: • Wear proper PPE for your environment, according to your local, national, and company protocols. Always remain the proper distance away from potentially hazardous equipment. • Have direct access to the target you are scanning. Disassembly may be required around your target.
