selectable in 12 or 24 hour format. The user can also select European or American
formats and auto daylight savings adjustment. See
Clock setup .
G
Zoom Scale Indicator
– shows the zoom scale for the channel indicated if > x1.
Separate scale for each channel. See zooming .
H
The right hand edge of the graphics area in which the traces are displayed. This is the
vertical scale area designated by the scale values at the top, center and bottom of the
scale. The most recent data that is displayed in digital form at the top of the display (J)
is against the right edge of this scale and moves left with time - the most recent data is
to the right and the oldest data is to the extreme left. New data appears against this
margin and the oldest data disappears off the screen at the extreme left. The graphic
cursor (K) will start against this right edge.
I
Vertical Scale Identifier – this display alternates between Channel A and Channel B. It
displays the Channel Tag and the Engineering units. See Channel setup .
J
Digital Window
– the top of the screen displays the values for each Channel including
the Channel identifier, the current value and the engineering units. Channel A is
displayed on the left and Channel B on the right. This window displays the absolute
digital value of the instantaneous (last) reading for the channel, and is the right most
sample value on the trend display (G), unless the cursor is active. In that case it
shows the value at the point the cursor intersects the trend line.
K
Cursor – is displayed when activated in the cursor ID mode. This cursor can be moved
using the left ◄ and right ► arrow buttons. The values in the digital window (J) are the
values at the point the cursor intersect the trend line.
L
Date/Time Axis Delimiter
– the dotted vertical lines placed at equal increments along
the Horizontal axes (Time). The Date/Time stamp beside the line indicates the exact
position of the line. Both date and time may be shut off or relocated vertically. These
lines move with the trace at a speed dependent on the sampling speed. This is
configurable in
Display Setup .
M
Channel B Trace
– the trend line is the graphic representation of Time (horizontal)
versus Amplitude (vertical) and is shown solid to distinguish it from the Channel A
trace, which is shown as a dotted trend line. This is configurable in
Display Setup .
N
Graphic TREND Window
– shows the channel traces, which may be compressed,
expanded, zoomed, scrolled and halted.
P
Status Icons
– these icons appear at various times to indicate the status of the unit
and the display. From left to right they are:

The numbers 1,2,3 and 4 are the ALARM indicators - one for each alarm. The
numbers are present when the alarm is enabled and will blink if the alarm is in an
alarm condition.

The X indicates the status of the EXTERNAL INPUT and is present when the
external input is present.

The

icon indicates the display is compressed. The horizontal time stamps
indicate the current compressed values. The display can function normally in
compressed mode, may be paused or the user can scroll back and forth using
the left ◄ and right ► arrow buttons.

The H indicates the display is in the HOLD condition. While in HOLD, the trends
do not update. The display enters the HOLD condition when the ID Cursor (K) is
present or the user scrolls in the horizontal dir
ection using the left ◄ and right ►
arrow buttons. Exit the HOLD mode by pressing the MENU button.
