PQA824
The PQA823 model uses Windows CE technology, permitting an easy and fast analysis of large quantities of data. Its innovative design and graphical colour TFT touchscreen display makes it flexible enough to meet your requirements, with an intuitive icon-based interface and context-sensitive help available for each screen. Each measurement parameter is listed in an Windows-style tree structure to make it easy to select what you want.
This Logger permits detection of fast voltage transients (spikes) with a minimum resolution of 5µs (200kHz). The ability to set different trigger thresholds is very useful for troubleshooting problems with industrial installations (monitoring atmospheric discharging, analysis of switching problems, frequency noise, etc..).
Parameters can be visualized in numerical and graphical form, with many options for waveforms and histograms display (for harmonic analysis). The vector diagram feature also allows evaluation of the mutual phase angle between voltages and current, allowing understanding of the inductive or capacitive loads in an installation.
Its internal memory (15Mbytes) allows for recording periods of e.g: >3 weeks for 251 parameters and measurement interval of 15 minutes. This memory can also be expanded using Compact Flash cards. USB Pen Drives can also be used to transfer recordings from the Logger for PC analysis. The USB interface permits connection to the PC for download and analysis of recordings, using the dedicated TOPVIEW Windows software.
The Logger is powered by a internal rechargeable Li-Ion battery with a >3 hour battery life, or an external 100/240V AC adaptor can be used.
