The HT PQA824 model permits an easy and wide fast analysis of a huge quantity of data any other system. Thanks to an innovative design and a graphic colour TFT "touch screen" wide display these models finally meet all requests from any exigent electrical verifier. The interface it's incredible "user-friendly" due to the intuitive icon selection of any kind of feature and a contextual help it's available for each screen. Each internal parameter it's easy to reach for effect of  typical Windows tree structure.

The model permits the visualization of all parameters both in numeric and graphical mode with large use of waveforms and histograms (for harmonic analysis) screens. The vectorial diagram feature permit also to evaluate the mutual phase angle between voltages and current in order to understand the nature inductive or capacitive of the loads on an installation.
