The monitor software can indicate maximum, minimum and average values, and have multiple
functions including dynamic display, real-time monitoring, alarming threshold setting, alarming
indication, data viewing/saving/printing, etc.
UT225B
has the same functions as High/Low Clamp Meter, Aerial Current Tester, and other
products.
