Placing an All-weather
Case on location
Logging in the Field
Unattended measurements require protection against weather
and unauthorised access, and the All-weather Case Type 3535-A
fills the bill. Lightweight and robust, it will house a Type 2250-H
Hand-held Analyzer and supply it with battery power for up to
90 hours of operation. A wide range of optional accessories are
available to tailor the system capability to the logging task.
Outdoor Microphone Type 4952 is shown in Fig. 12. When the
system is left unattended, measurements and status can be
monitored remotely with a wide range of options (see the
Connectivity section).

Charge Injection Calibration (CIC)
Measurement integrity is vital in any measurement application,
particularly if the system is operating unattended. CIC provides a means
of regularly auto-checking the measurement system for 10 s to ensure
the continued and accurate operation of the system.
With the Logging software, CIC can be set to run at the beginning and
end of measurement.
With the Enhanced Logging Software BZ-7225, CIC can be programmed
to run at up to four user-specified times in each 24 hour period. It may
also be activated manually.

Metadata the Easy Way
Metadata are supplementary information about your measurement to
help in archiving, retrieval and post-processing. Examples of metadata
are the file name, date and time, setup and annotations made by
the operator.
The names and types of up to 10 text strings can be further defined. The
type may be text you enter, text from a pick list you define, a number you
enter or an index number that is automatically incremented or
decremented when the measurement is saved.
Metadata are available in all applications and may be used for sorting
measurements in Measurement Partner Suite BZ-5503.
