Details
When this attribute is set to true, the power line frequency is detected automatically the next time
the Model 2651A powers up. After the power line frequency is automatically detected at power-up,
the localnode.linefreq attribute is set automatically to 50 or 60.
If the localnode.linefreq attribute is explicitly set, localnode.autolinefreq is automatically
set to false.
When using this command from a remote node, replace localnode with the node reference, for
example node[5].autolinefreq.
