Single VOAC7523/7520 unit, equipped with a 2-channel DC measuring
input and dual display, can perform DC voltage measuring that
normally requires two units and thus saves installation space
and improves measurement speed. The VOAC7522/7521A, equipped
with one input channel and dual display, can perform current
or frequency measuring simultaneously with voltage measuring.
The VOAC7522/7523 realizes the high resolution of direct-current
voltage measuring at 0.1μV and broad bandwidth of alternating
voltage at up to 300kHz.
