Page 40: Dataview Software
AEMC’s DataView software enables a computer to connect to and interact with a variety of AEMC instruments, including the Models 6526, 6532, and 6534. DataView includes a core set of features used by all instruments. These features are designed for viewing recorded data; and for opening, creating, and saving DataView reports. DataView also includes appli- cations called Control Panels for interacting with the instrument. -
Page 41: Megohmmeter Control Panel
You can access DataView through the Control Panel, and access the Control Panel via DataView. For users who interact with a single type of AEMC instrument, we recommend primarily using the Control Panel. For further information about DataView and its capabilities, or for information about using the Megohmmeter Control Panel, consult the Help system that comes with the product. -
