FUNCTION
Range: Disabled, Continuous, Triggered
Default: Continuous
This setting configures the mode in which the data logger operates. When set to
"Continuous", the data logger actively records any configured channels at the rate as
defined in Data Logger Rate setting. The data logger is idle in this mode if no channels
are configured. When set to "Triggered", the data logger begins to record any configured
channels at the instance of the rising edge of the trigger (FlexLogic operand). The data
logger ignores all subsequent triggers and continues to record data until the active
record is full. Once the data logger is full, a Clear Data Logger command is required to
clear the data logger record, before a new record can be started. Performing the Clear
Data Logger command also stops the current record and resets the data logger to be
ready for the next trigger. The Clear Data Logger command is located under Records/
Clear Records menu. The table below shows an example on the dependency of the data
logger storage capacity with respect to the selected number of channels, and the
selected rate (time interval) at which the logged values are taken. The Data Logger
