PQA820 is the innovative proposal by HT to easily analyze all involved components on a three-phase or single-phase electric system. When designing them, HT has taken particular care of three aspects:
Further to the Wi-Fi connection, PQA devices are provided with USB connection for transferring data via cable to the PC through the provided Top View software. They do not need any batteries since they are auto power-supplied from the mains they are analyzing. The internal battery is automatically recharged by the input voltage. It will provide the necessary energy to go on recording in case power supply is interrupted. To make the most of the technology used by PQA820 and PQA819 we recommend using the HTanalysis App (available for free download on AppStore and Google Play) on a tablet or smart phone.
