Term: volts
SI unit for electrical potential.
Term: VSPECT
trademark for Campbell Scientific's proprietary spectral-analysis, frequency
domain, vibrating wire measurement technique
Term: watchdog timer
An error-checking system that examines the processor state, software timers,
and program-related counters when the CRBasic program is running. See
section Watchdog Errors
(p. 514).
The following will cause watchdog timer
resets, which reset the processor and CRBasic program execution.
o
Processor bombed
o
Processor neglecting standard system updates
o
Counters are outside the limits
o
Voltage surges
o
Voltage transients
When a reset occurs, a counter is incremented in the WatchdogTimer entry
of the Status table
(p. 573).
A low number (1 to 10) of watchdog timer resets
is of concern, but normally indicates that the situation should just be
monitored.
A large number of errors (>10) accumulating over a short period indicates a
hardware or software problem. Consult with a Campbell Scientific support
engineer.
Term: weather-tight
Describes an instrumentation enclosure impenetrable by common
environmental conditions. During extraordinary weather events, however,
seals on the enclosure may be breached.
Term: web API
Application Programming Interface.
