HT Italia PQA823 is three-phase power analyzers that allows for the analysis of all electric parameters which can be measured nowadays, elaborating them easily and quickly. The HT Italia PQA823 can be easily programmed thanks to the new colour touchscreen display with icon menu, which guarantees the selection of internal parameters in a simple and intuitive way. The Help online function available on each screen is a valid and concrete help for the operator in understanding how the devices are used. Each internal parameter is easily reached through the typical tree structure, widely known to Windows system users. The HT Italia PQA823 allows displaying the parameters in numerical and graphic mode, both for periodical analysis and for harmonic analysis. The graphic function “vector diagram” allows, among other things, to immediately evaluate the phase angle between input voltage and current signals, thus defining the loads’ nature. The 15MB internal memory allows saving recorded data for a remarkable number of consecutive days.
The HT Italia PQA823 power quality analyzer and energy logger has a large internal memory in order to save recording results of parameters (e.g: >3 weeks for 251 parameters and integrated period of 15 minutes), but this memory can be expanded by using of external compact flash cards fitted on meters. USB flash drives cal also be used to transfer recordings from meter. PQA823 meter is powered by a internal rechargeable Li-Ion battery which permits complete operation for more than 3 hours and long term using the supplied 100/240V AC adaptor. USB interface permits the connection with PC for download and analysis of recordings with dedicated TOPVIEW software.
