prompting and control (hide/show) error messages on the display.
localnode.linefreq
Attribute Power line frequency.
Usage
frequency = localnode.linefreq
localnode.linefreq = frequency

• To achieve optimum noise rejection when performing measurements at integer
Remarks
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),
the Remote Master node only. Use

TSP-Link.
• When this attribute is set, the localnode.linefreqauto attribute will be
automatically set to false.
Also see localnode.linefreqauto
Example Sets the line frequency to 60Hz:
localnode.linefreq = 60
Set to 50 or 60.
