The non-contact voltage tester has its own opinion and the temperature sensor has a deviation of about 20 degrees compared to the other two gauges and the field thermometer. The thermocouple will also go OL if you touch it during operation, indicating a wiring problem. Everything else seems to work, but other issues have me arguing about the accuracy of the whole thing. I bought extech based on Flir's reputation as I have used Flir devices in the past. I now think I should have bought a leech or a field piece.
