1. Introduction
The BetaLOG TI application is used to configure data logging parameters
in the BetaProbe TI and TI+ temperature probes, and to retrieve logged
data from the probe for storage and analysis on a personal computer.
2. Description
The probe can log multiple sets of data, each of which is identified by a
sequential run number. Data logging runs are started and stopped using
items on the probe’s SETUP menu sequence. Logging parameters can
be changed from one data logging run to the next, and data logging runs
may be as short as a single sample or as long as the maximum storage
capacity of the probe.
The probe has a capacity of 10752 data records for storing run
identification data and log sample data. Each new data logging run
requires 1 record for run identification overhead, and one record is
required to log each sample.
The interval time setting determines the frequency of sample calculation
and storage. Six discrete interval times are available, ranging from 1 to 60
seconds. The following four values are calculated and saved at the end of
each interval based on all of the temperature measurements made during
that interval:
• Last value in the interval
• Minimum value over the interval
• Maximum value over the interval
• Average of all values over the interval
The data logging function is disabled by default in all new probes. The
BetaLOG TI application is used to enable and disable the data log function
in a probe.
3. Probe Operation
3.1 Data Logging Disabled
Until data logging functionality is enabled using the BetaLOG TI
application, the probe operates as described in the user manual received
with the probe.
3.2 Data Logging Enabled
Once data logging functionality is enabled, a new item is inserted at the
start of the SETUP menu tree to direct the user to a completely separate
branch which contains all data logging functions. This new menu item
shows ‘LOG’ in the main display and ‘DATA’ in the secondary display.
Press the SETUP key to proceed to the existing configuration functions, or
press the ENTER key to proceed to the new data logging branch. The
data logging configuration menu sequence (new branch) is as follows:
