localnode
attributes
The attributes in this group are used to set the power line frequency, control (on/off)
prompting and control (hide/show) error messages on the display.
localnode.linefreq
Attribute
Power line frequency.
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 num-
ber) to send the command to any node in the system. See
for details on
TSP-Link.
• When this attribute is set, the
localnode.linefreqauto
attribute will be
automatically set to false.

Example
Sets the line frequency to 60Hz:
localnode.linefreq = 60
