Note: You can only change sample intervals if you set the Clear Mode to the
Clear logger setting (see Setting the Clear Mode on page 22).
To change the sample interval on the currently-connected logger:
1. Select Logger>Sample Timing....
2. Under Sample Interval, use the drop-down lists to set the Days, Hours,
Minutes, and Seconds to the desired sample interval.
If you want to use a sample interval of once per minute, click the Default
button.
You can choose intervals ranging from a minimum of ten seconds to once
every 24 hours.
The total period covered by a logger before the memory is full depends on
how many channels are enabled and the sample interval. This information
is automatically calculated in the Log Time section of the Logger Sample
Timing window.
Note: Running the logger with a sample interval shorter than one minute for a
prolonged time shortens the battery life.
Enabling and Disabling Logger Channels
The Logger Channels option enables you to enable or disable the channels on
the currently-connected data logger.
Note: During this process the data logger’s memory is cleared. If the informa-
tion on the data logger is still of value, transfer the data to a PC before
enabling or disabling channels.
