7.5 How to start data logging
7.5.1 Data logging start
There are 2 ways to start data logging. One is with the
key, and the other is
using the external operation input.
Data logging start with the
key
Press the
key.
Data logging starts under conditions which have been set during Data logging
condition setting mode.
The LOG indicator is lit during data logging, and flashes while writing to the CF card.
Data logging start using the external operation input
Connect External operation input LOG terminals 19 and 20 (Contact from Open to Closed).
Data logging starts under conditions which have been set during Data logging condition
setting mode.
The LOG indicator is lit during data logging, and flashes while writing to the CF card.
7.5.2 Logging auto-start function
If “Effective” is selected during “Logging auto-start selection” in Data logging condition
setting mode (p.23), Logging auto-start function will initiate after power-on.
Logging automatically starts between Auto-start start and end time.
If Logging auto-start start and end time are the same, logging continues until power-off or
until CF card capacity is exceeded.
After power is restored, Auto-start function is enabled if logging is within the selected time
between Auto-start start and end time, and logging is performed.
During logging, usual Logging start/stop can be performed.
During logging, if external operation input LOG terminals 19 and 20 are connected
(Contact from Open to Closed), logging will continue even if the logging end time has
expired.
Even within the data logging time, logging stops by disconnecting LOG terminals 19 and
20 (Contact from Closed to Open).
7.5.3 CF card file
Every time the LMD-100 starts data logging, LMD-100 writes the data in a new file.
When logging data reaches 65,000 lines, the file is closed and a new file is opened for
data writing, considering editing on spreadsheet applications.
The file is named as shown below.
yymmdd_hhmmss.CSV
yy : Lower 2 digits of the year (2006: 06)
mm : Month (January: 01)
dd : Day (the 1st : 01)
hh : Hour (8 a.m.: 08, 8 p.m.: 20)
mm : Minute
ss : Second
For example, if data logging is started at 8:30 a.m. on January 1st, 2006,
the file will be named as “060101_083000.CSV”.
