Line frequency configuration
The factory configures the Series 2600B to automatically detect the power line frequency (either
50 Hz or 60 Hz) at each power-up. This detected line frequency is used for aperture (NPLC)
calculations.
In noisy environments, you can manually configure the instrument to match the actual line frequency.
To configure the line frequency from the front panel:
1. Press the
MENU
key, then turn the navigation wheel
to select
LINE-FREQ
,
and then press the
ENTER
key.
2. Turn the navigation wheel
to select the appropriate frequency and then press the
ENTER
key.
To configure the instrument to automatically detect line frequency at each power-up, select
AUTO
.
3. Press the
EXIT (LOCAL)
key to back out of the menu structure.
To configure the line frequency from a remote interface:
Set the
localnode.linefreq
or the
localnode.autolinefreq
attribute. The following
programming example illustrates how to set the line frequency to 60 Hz:
localnode.linefreq = 60
The following programming example illustrates how to remotely configure the instrument to
automatically detect line frequency at each power-up:
localnode.autolinefreq = true
Fuse replacement
A rear panel fuse drawer is located below the AC receptacle (refer to
Rear panel
(on page 2-6)). This
fuse protects the power line input of the instrument. If the line fuse needs to be replaced, refer to
Line
fuse replacement
(on page A-1).
