Display
The Series 3700 display provides visual information on the present active
channel, including the channel selected (or range or pattern), channel state, last
DMM measurement reading (where applicable), DMM settings (where
applicable), and error indications. The display and the navigation wheel provide
a way to change the active channel or channel ranges, as well as access, view,
and edit the various menus and menu items.
The Series 3700 has three LEDs on the front panel; these LEDs represent 1588
status, LAN status, and power.
When you turn on the unit, the power LED is illuminated.
When the instrument is connected through the Ethernet with no errors, the
LAN status LED is illuminated. However, the LAN status LED is off when the
instrument is not connected through the Ethernet or there is a connection
problem.
When you press the identify option (ID button) on the home web page for
the Series 3700, the LAN status LED blinks.
The 1588 status LED indicates 1588 operation. When this LED is off, the
1588 feature is disabled or improperly configured.
The LED blinks at a one-second rate when the instrument is the 1588
master. If the instrument is a slave, the LED will not blink.
See the following figure (labeled "Active channel display example") for an active
channel example. The 4W and AUTO range annunciators are lit (1). Also, the
active channel is 1004 (Slot 1, Channel 004) (2). The present state of the
channel is open and it has two poles (3). The present state of the attributes for
this channel (4) are:
4W function set for AUTO range
Dry-circuit ohms disabled (DRY-)
Offset compensation off (OC-).
Other attributes, such as NPLC, are available for this specific active channel
(1004) as indicated by arrow (5) being lit. View them by turning the navigation
wheel (6) to scroll through the attribute list.
NOTE
Access attribute and menu lists that are larger than the display by
turning the navigation wheel (6). Displayed arrows (5) indicate
additional attributes or menu items (as applicable) that are available
by turning the navigation wheel (6) in the direction the arrow points. If
an arrow (5) is not displayed, there are no additional menu choices in
that direction. Switch-only systems have none of these features.
