bold
The SCC-A10 voltage attenuator module accepts up to two voltage sources
of 60 V maximum amplitude and attenuates each voltage by a factor of 10.
A differential instrumentation amplifier buffers each input signal. The
SCC-A10 contains circuitry capable of protecting E/M Series DAQ
devices for input signals up to 60 VDC.
The following conventions are used in this guide:
Angle brackets that contain numbers separated by an ellipsis represent
a range of values associated with a bit or signal name—for example,
AO <3..0>.
The » symbol leads you through nested menu items and dialog box options
to a final action. The sequence File»Page Setup»Options directs you to
pull down the File menu, select the Page Setup item, and select Options
from the last dialog box.
This icon denotes a note, which alerts you to important information.
This icon denotes a caution, which advises you of precautions to take to
avoid injury, data loss, or a system crash. When this symbol is marked on
the product, refer to the Read Me First: Safety and Radio-Frequency
Interference document, shipped with the product, for precautions to take.
When symbol is marked on a product, it denotes a warning advising you to
take precautions to avoid electrical shock.
When symbol is marked on a product, it denotes a component that may be
hot. Touching this component may result in bodily injury.
Bold text denotes items that you must select in software, such as menu
items and dialog box options. Bold text also denotes parameter names.
