If you configured the SCC-A10 using Measurement & Automation
Explorer (MAX) and you are using NI-DAQ, the voltage reading you get
from the E Series DAQ device accounts for the voltage scaling effect of the
SCC-A10. Otherwise, because the voltage measurement from the E Series
DAQ device is one-tenth of the voltage applied at the SCC-A10 input, you
must multiply the voltage reading from the E Series DAQ device by 10 to
get the correct SCC-A10 input voltage.
These ratings are typical at 25 °C unless otherwise stated.
