4.3 DATA
LOGGING
Data Logging Options
Log Type - Manual or Automatic
Log Storage - Memory, RS232
Log Output - RS232
Log Type: There are two options: Manual or Automatic
Manual: The manual data log provides an instantaneous log of data at that precise time. This can be
undertaken by pressing the 'LOG' key in the Gas Readings Display.
Automatic: The automatic data log enables data to be logged at specific time intervals for a specified
time period of logging i.e. Log Period 2 mins, Log Interval 10 secs.
— The 'Log Period' has a range 2 - 60 mins.
— The 'Log Interval' has a range 10 -1800 secs
NOTE: Although the sample interval may be set as low as 10 seconds, the system response to
changes in gas concentrations is not less than 1 minute.
Log Storage: There are three options available to enable data logging storage/output - Memory,
Printer or RS232.
Log to Memory: The Firetron 1000 can log up to 963 log records of data in non-volatile system
memory.
NOTE: When the log memory is full no subsequent logs are recorded.
Log to Printer: Log records may be output as ascii text to a serial printer.
NOTE: Due to the limitations of a specific printer type, the number of continuous printouts is limited
by the buffer size - e.g. by dumping the data log memory.
If the serial printer has only a small internal buffer, it may overflow and the number of printouts may
be limited.
If the requirement is for multiple printouts and the buffer is insufficient in size, then two options are
available.
1.
Send the print/serial output to a file using something similar to a Windows Hyperterminal. The
information can then be printed using standard Windows print facilities.
2.
Use the Fireye CAPTURE Program to CAPTURE the data in the spreadsheet format and use a
standard spreadsheet program to manipulate and print the data.
Log to RS232: Each log record may be output to the RS232 channel. The data is output as ascii data
which may be received by the Fireye CAPTURE PROGRAM for use with a spreadsheet.
See Fireye CAPTURE PROGRAM Section 10.
Log Output
RS232 OUTPUT: When the 'LOG TO' parameter is selected as RS232 this parameter determines the
output format of the data.
ASCII Text: Data is output as ascii text.
A serial printer with XON / XOFF protocol may be connected to the serial channel for a hard copy
report of the samples. Alternately a PC with a suitable communications package could CAPTURE
the data for output to a disk-based data file.
NOTE: Data in this format may not be directly incorporated into a spreadsheet package.
ASCII Data: Data is output as ascii data in a format which may be received by the Fireye CAP-
TURE SOFTWARE for use with a suitable spreadsheet package.
