Channels to Log : This option only appears if the device has more than one channel. You can elect to disable
unused logger channels. When a channel is disabled, its memory is allocated to the other channels, increasing
the total logging time. The total logging time will be reflected in the
Sample Interval window. Depending on
the logger, some channels are required and cannot be disabled. Channels that can not be disabled are grayed out
and can not be unchecked. For instance, in the picture above, the Temperature channel is required to record
Relative Humidity, so the Temperature channel cannot be disabled. At least one channel must be enabled for
logging.

Custom Interval Setup
Commonly used intervals are predefined in the Sample Interval box in the Logger Setup screen . A custom interval
can also be defined by the user. To do this, click on the Custom Interval button in the Logger Setup screen. The
custom interval window is shown below. You can select a custom logging interval using this window.
In the window above, the sampling interval was set to 1 minute, 20 seconds, to allow about 20 days of recording.
Alarm Setup
Alarms are used to indicate if the data inside the logger exceeded a user specified threshold. This can be an
indication that an important event has occurred. The logger will indicate that an alarm condition has occurred by
displaying the
Alarm icon . Once an alarm condition has occurred, the alarm icon will remain turned On for the
duration of the logging session to indicated that data stored in the device memory has alarms in it.
To get to the Alarm Setup window, click the Alarm Setup button in the Logger Setup screen . The Alarm Setup
windows allows you to set high and/or low alarm thresholds for each data channel, or disable these alarms. Alarms
are set by entering the thresholds as shown in the window below.
