Timekeeping
The S10 logger has an internal battery to maintain the time and date when the power to the unit is
switched off. The clock has been factory set to UTC time. When it is necessary to reset the time and
date (or switch to a local time zone), please follow the steps below.
To set the time and date for correct stamping of the data records, a file named SETUP.TXT must be
created on the SD card. This file is read by the logger when the card is inserted into the logger and the
purge button is pressed.
Create the Setup File
File contents:
WAIT
TIME=hh:mm:ss
DATE=DD/MM/YYYY
1)
Install the memory card in the memory card reader.
2)
Plug the memory card reader into a USB port on your Windows computer.
3)
Use File Explorer to find and open the SETUPOLD.TXT file that is on the card.
4)
Change the TIME to some value a few minutes in the future, when you will synchronize the clock.
5)
Change the DATE parameter to the current date in this format: DD/MM/YYYY
6)
Choose File / Save As and enter the file name SETUP.TXT then click Save.
7)
In File Explorer, locate the USB Drive representing the memory card, right-click and select "Eject".
When Windows indicates it is safe, remove the memory card reader from the computer.
Synchronize the Clock
1)
Connect power to the logger.
2)
Insert the memory card into the logger (fits easily one way only – do not force). Both LEDs will
turn on and stay on (the logger is executing the "WAIT" function).
3)
At the time saved in the SETUP.TXT file, press the button to the left of the card slot. The logger
will "Beep" once and both LEDs will turn off. Release the button.
4)
The red LED may flicker on and off. Once the card has completed its initialization the green LED
will come back on and remain on. The logger will begin storing any data received.
5)
After updating the time and date, the logger renames the file SETUP.TXT to SETUPOLD.TXT to
avoid unintentionally repeating the commands next time the unit is switched on or the card re-
inserted.
