4.3 Overview of Options
The screen of the computer is updated every 5 seconds with the logger time, date and sensor data.
When the
W
ATER
WARE
TM
program is running, it issues a command to the “
W
ATER
LOG”
telling it to provide the information displayed on the next screen update. When connected to the
“
W
ATER
LOG” and running the
W
ATER
WARE
TM
program, the “
W
ATER
LOG” will change to a
continuous operating-power mode from the low-power mode to be able to respond to commands
from the computer. This continuous operation shortens battery life and should not be used for
long periods in the field unless you are willing to replace the battery more frequently. However,
an external 12 volt power source can be connected via the RS-232 communications connector to
elevate power drain on internal lithium battery pack.
