Description
Overview
GAOTek logger quality recorder electrical delay network analyzer is a dedicated portable product for detecting and analyzing power quality parameters. Power quality parameters include frequency, voltage or current amplitude, harmonics, inter-harmonics, unbalance, voltage flicker, power factor, etc. In addition, it can carry out long-term data collection and monitoring on the operation of the power grid. At the same time, it is equipped with power quality data analysis software to perform various analyzes on the measurement data uploaded to the computer.
Features
- Use ARM and DSP and 16 M bytes of memory
- A touch screen to make the operation easier and more convenient
- Can measure, save the data and upload it to PC for analysis
- Chinese or English menu operation, simple and easy to operate
- Software can be updated using a USB disk
