First observation was the use of a third-party Calibration Lab. It appears the Cal Lab is performing improper calibration methods since the ‘Cal. Date’ on all units still read 2016. Proper calibration is an integral part of having reliable test results. Operator safety was another main topic. During the testing process, it was observed that operators’ hands were resting on the water heater. Also, operators’ legs were, at times, contacting DUTs while sitting in the chairs used during testing. Additionally, with no ‘Lo-limit’ set and the use of probes for quick contact in a conveyor setting, it was very easy for operators to attempt to tap the mains cable, miss, yet still pass. On that basis, understanding test results and parameters were a focus of the training. An assembly line was found using a frayed cable which was passing every product. The duration of this situation was unknown; therefore, a large inventory may have been shipped without getting tested. A lack of a verification method was also discovered. This is required for those who test with UL, thus, recommendations were made to integrate a TVB-2 within their testing processes.
