Sample Continuously: Clicking this check box causes the Global Logger software
to take and display a real-time reading once per second until stopped by clicking it
again, as well as update the rest of the fields on the screen. These data readings
are not stored in the historical record and do not affect the normal recording of the
logger. The initial reading has a sensor warm-up time of 50mS and the sensor is left
powered up until this feature is turned off.
Get Sample: Clicking this button causes the Global Logger software to take and
display a single reading as well as update the rest of the fields on the screen. This
data reading is not stored in the historical record and does not affect the normal
recording of the logger.
Get History: This button starts the download of all the historical data stored in the
logger memory. Oldest data is collected first and Clicking “Stop” halts the process.
This function is described in detail later.
Clear History: This resets the number of recordings in memory to zero. The user is
warned first and must confirm the action before the memory is cleared.
Sync Time: This button causes the data logger’s internal clock to be set to the
system time of the computer it is connected to. The user is warned first and must
confirm the action before the time is set.
Setup: Clicking this button enters the setup screen where the user can change and
program all parameters into the data logger. This function is described in detail later.
Bar Graphs: The bar graphs show a visual representation of the most recent data
reading taken by using the Sample Continuously or Get Sample functions. The
upper and lower limits of the display are defined by the user as discussed in detail
later.
