Digital LCR Meter (AT3818)

AT3818 adopts TFT true color LCD display and English operation interface. AT3818 (has been upgraded into continuous frequency with the resolution of 0.001Hz. Four parameters can be measured simultaneously by AT3818. Any parameters can be set arbitrarily. Both main & sub parameters can be displayed in 6 dgt after the improvement. AT3818 can not only scan 10 kinds of frequency or voltage level, but also correct three groups of user frequency so as to improve the accuracy. The upgrade version adopts big font. With DCR and DC bias function.
