Serial Number
Unique eight-character product serial number of the currently-connected data
logger. This number should match the serial number label on the back of the
data logger.
Logger Status
Indicates the sampling status of the currently-connected data logger. The pos-
sible modes are:
• Sampling: The logger is currently taking samples and the memory is not
full.
• Sampling (wrapped): The logger is currently taking samples with the
memory full. The oldest reading is discarded and replaced with the newest.
• Stopped at specified time: The logger is not sampling and has stopped
because the user-set stop time has been reached.
• Stopped when full: The logger is not sampling and has stopped because it
is configured to stop when the memory is full.
• Start at specified time: The logger is not sampling, but is set to begin sam-
pling as soon as the Start time is reached.
• No enabled channels: The logger is not sampling because no channels are
enabled.
The Setup button to the right of the Logger Status enables you to clear the log-
ger’s memory and change the Sample Interval, Start Mode, and Stop Mode
settings.
Start Time
Indicates either the time that the currently-connected data logger began taking
samples, or the time (in the future) that it is set to begin taking readings
Future Start times are indicated by a (
) symbol.
For information on changing the Start Time, see
Sample Interval
Indicates the current sample interval setting (how frequently the data logger is
programmed to take readings). For information on setting sample intervals,
see
Setting the Sample Interval on page 34
Note:
The most frequent sampling rate possible with VL-1000-VLT, VL-1016,
SP-1016, VL-1416 and SP-1416 loggers is once per minute. For other
loggers, the most frequent sampling possible is once every 10 seconds;
however, sampling of this frequency will have a negative effect on bat-
tery life.
Stop Mode
Indicates how the currently-connected data logger is set to stop while record-
ing samples in its memory. There are three choices: Wrap when full, Stop
when full, and Stop at specified time. For more information on setting Stop
modes, see
Setting the Stop Mode on page 33
.
Stop Time
Indicates the programmed Stop Time, if set.
If a Stop Time has not been set, it reads None.
For information on setting the Stop Time, see
Samples per channel
Identifies how many samples have been stored for each enabled channel on
the currently connected logger, the capacity available (in samples) for each
channel, and the percentage of memory used
Click the Refresh button to update values.
Log Time
Identifies the length of time the data logger has been recording.
The value is based on the number of samples in the memory multiplied by the
sampling interval.
