Glossary
These terms are in common use throughout the manual:
A/D Value:
the digital representation of the analog voltages in an analog- to- digital (A/D)
conversion. The accuracy of the conversion is dependent on the resolution of the system
electronics; higher resolution produces a more accurate conversion. Also referred to as "bits".
ASTM:
The Association of Standards and Testing is a nationally-accepted organization for the
testing and calibration of technological devices.
Base Station:
The base station is the transceiver that attaches to the host computer and
provides communication between the software and the node(s). It is also referred to as a
“gateway”.
Bits:
the digital equivalent of voltage on the node. See 'A/D Value'.
Burst Sampling:
a mode of operation in synchronized sampling that takes momentary high
sample rate readings with configurable time durations and intervals
Calibration:
to standardize a measurement by determining the deviation standard and
applying a correction (or calibration) factor
Configuration:
a general term applied to the node indicating how it is set up for data
acquisition. It includes settings such as sampling mode and rate, number of active channels,
channel measurement settings, offsets, hardware gain, and calibration values.
Coordinated Universal Time (UTC):
the primary time standard for world clocks and time. It
is similar to Greenwich Mean Time (GMT).
Cycle Power:
a command transmitted to the node to reboot it, either through a hardware or
software switch
Data Acquisition:
the process of collecting data from sensors and other devices
Data Logging:
the process of saving acquired data to the system memory, either locally on
the node or remotely on the host computer
DHCP (network):
Dynamic Host Configuration Protocol is the standardized networking
protocol used on Internet Protocol (IP) networks, which automatically configures devices that
are attached to it by assigning and configuring the device IP address.
