localnode.gettimezone
Function Retrieves the local time zone.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage timezone = localnode.gettimezone()
timezone Returns the timezone.
Remarks • See localnode.settimezone for additional details on the time zone format and a description
of the fields.
• timezone can be in either of the following formats:
• GMThh:mm:ss
• GMThh:mm:ssGMThh:mm:ss,Mmm.w.dw/hh:mm:ss,Mmm.w.dw/hh:mm:ss
• The first format is returned if one argument was used with localnode.settimezone.
• The second format is returned if four arguments were used with localnode.settimezone.
localnode.linefreq
Attribute Power line frequency.
Default 60
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage frequency = localnode.linefreq --Reads line frequency.
localnode.linefreq = frequency --Writes line frequency.
frequency Set to 50 or 60.
Remarks • To achieve optimum noise rejection when performing measurements at integer NPLC apertures,
the line frequency setting must match the frequency (50Hz or 60Hz) of the AC power line.
• When used in an expanded system (TSP-Link), localnode.linefreq is sent to the remote
master node only. Use node[n].linefreq (where n is the node number) to send the command
to any node in the system. See
Section 14 for details on TSP-Link.
• When this attribute is set, the localnode.autolinefreq attribute is
automatically set to false.

localnode.autolinefreq
Example Sets the line frequency to 60Hz:
localnode.linefreq = 60
localnode.model
Attribute The instrument model.
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage model = localnode.model -- Reads the node model.
model The model number of the instrument.
Remarks • This is the model number of the instrument.
