information on setting and using alarms.
GDL-T Difference Screen
When four channels are selected to log, or when the GDL-T is idle, the unit will display an additional temperature
difference screen. The temperature difference is always displayed between the Internal Channel (Temp Int) and
Channel 1 (Temp 1), and between Channel 2 (Temp 2) and Channel 3 (Temp 3).
When less than four channels are selected to log, the temperature difference will be displayed on the sample screen.
GDL-T Summary Screen
The Summary screen is shown below.
The icons in the summary screen are identical to the icons in the Sample screen. The Summary screen shows:
• The User Information: This 30 character text field is entered through the DwyerLog setup software, and
can be any text that describes the logger
• Logging Rate: Is the rate at which the data in memory was logged at.
• Samples: Shows the number of samples stored in memory. If a rollover has occurred this number will
show the maximum number of samples that can be stored in the logger, and will not change, even though
the logger may be logging.
• Mem Used: Shows the length (in days, hours, minutes or seconds) of data currently stored in memory. If a
rollover has occurred, this number will show the maximum length of data that can be stored in memory, for
a given sample rate. If a rollover has occurred, this number will not change even though the logger may be
logging.
• Mem Left: Shows the length (in days, hours, minutes or seconds) of data the logger can record without
overwriting currently recorded data (record without a rollover). If a rollover has occurred, this number will
show 0 Sec, even though the logger may still be logging.
