the actual percent full. As the memory fills, warning messages will be displayed at the
bottom of the screen. When the memory is above 70% full, the message will show
“Filling Up”, and at 90% the message will be “Dump Soon”. If the memory becomes full,
the sensor will continue to log data but the oldest data will be overwritten and lost. This
window may be moved and resized.
Status Window:
The status window lists several items pertaining to the operation of the sensor when one
is “Attached” and other information when a sensor is not attached.
Line 1, Status:
This indicates what mode the software and sensor are in.
Stand-Alone Mode:
This mode indicates that the software is running independently of the sensor.
A logger may be physically connected but not “Attached” by software.
Reset Mode:
The sensor is attached and has been reset. All data memory has been cleared
and ready to log new data.
Run Mode:
The sensor is attached and is logging data to memory.
Off Mode:
The sensor is attached and logging is suspended. Data is still in memory, and
if logging is restarted, the new data will be appended to the old data.
Line 2, Logging Mode:
This line shows the logging mode. If a sensor is attached, it is the logging mode of
the sensor. If no sensor is attached, it is the mode defined by the software options.
The logging modes are Linear, Delta, Hyper, Hyper/Delta, and Variable. (See
section 4.4.3 for definitions of each logging mode)
Line 3, Time:
If a sensor is attached, this is the time in the sensor. If a sensor is not attached, this
is the PC time. This will update every second with no sensor attached and every 5
seconds with a sensor attached.
Line 4, Date:
If a sensor is attached, this is the date in the sensor. If a sensor is not attached, this
is the PC date. This will be updated about every 5 seconds.
