The Mini-KLA makes it possible to measure the electrical characteristics of photovoltaic modules without the need for expensive and complicated laboratory equipment. The Mini-KLA photovoltaic electrical-characteristic analyser is operated with just two keys and is as convenient and fully automated as a multimeter. Settings for measurement areas, sampling rate, data storage and data transfer to a PC are performed and optimised within the device. The latest technology and optimisation in data collection have made this convenient operation possible at an affordable price.
