8.3 Freezing the Display and Navigating
Data in TOP View
While operating in TIMED TOP View mode, the Knob
Emulator / TOP View Control Menu can be turned on or
off by pressing
. As shown in Figure 8-7, this menu
pauses, clears, and restarts the TOP View data acquisi-
tion process. Pressing
below STOP (this is the only
menu selection that’s also active in ENCODED mode) has
the same effect as pressing
: the display is frozen and
available for analysis or storage in a data set. To navigate
and evaluate a frozen TOP View display, follow the steps
below and refer to
Figure 8-7:
NOTE: While scanning in ENCODED mode, TOP View
data is first added to the display screen, then scrolled
into the instrument’s data buffer. When the buffer is full
the scanning process automatically stops, activating the
Frozen TOP View Menu (
Figure 8-7) and requiring the
operator to take action before the data is overwritten.
Saving this data to a data set file, generating a report,
or otherwise carrying out an ACTION indicated in the
FILES Menu clears the buffer.
NOTE: The TOP View Control Menu is activated and
deactivated by pressing
. When the Control Menu is
active, the function keys and both knobs are disabled,
but pressing
or
(in TIMED MODE) provides im-
mediate access to various HOME-Menu functions. Sim-
ilarly, when acquiring data in ENCODED mode (during
which no function adjustments are allowed), pressing
below STOP and pressing
or
provides ac-
cess to several functions that require recalculation of
instrument parameters. As this recalculation will result
in a clearing of unsaved TOP View data, the operator
is asked to confirm this action before proceeding.
NOTE: STOPping the data acquisition process and
saving this data to a data set file, generating a report,
or otherwise carrying out an ACTION indicated in the
FILES Menu clears the buffer.
NOTE: Pressing
below CLEAR (TIMED mode
only), while the TOP View is acquiring data, immedi-
ately eliminates all unsaved TOP View data and restarts
the display acquisition process. When the TOP View
display is STOPped (or frozen), pressing
below
START also eliminates all unsaved TOP View data and
restarts the display acquisition process while RESUME
(not displayed when the ENCODED mode buffer is full)
allows the acquisition to continue from its position when
STOP was selected.
Step 1: With TOP View operating and the TOP
View Control Menu displayed (
Figure 8-7), press
below STOP to freeze the TOP View display (pressing
has the same effect).
Step 2: The Frozen TOP View Menu appears
(Figure 8-7). Choose from the following menu
selections:
CURSOR 1 – Switch on the VERTICAL cursor, allowing
left- and right-knob control of the cursor lines. All mea-
surement of displayed TOP View data is made at the
intersection of the two cursors.
MEAS 1 – Sets the position at which these four measured
values (the only ones available for a TOP View display)
are reported.
VIEW – Chose for display one of the four TOP View DATA
SOURCEs. Shows all acquired TOP View data on one
screen or reverts to the scale used during data acquisi-
tion. Scrolling is only enabled when the VIEW WINDOW
is set to AS AQUIRED.
FILENAME – Sets the data set- and report-saving param-
eters, then stores data sets or generates reports. Note that
pressing and holding
for approximately three seconds
will cause a REPORT to generate or a DATA SET to be
stored based on the ACTION setting.
Step 3: Press
at any time to access the TOP View
Control Menu. Press
below START to eliminate all
unsaved TOP View data and restart the display acquisi-
tion process. Alternatively, press
below RESUME (if
displayed) to continue the acquisition process from the
point at which it was STOPped.
NOTE: When the TOP View display is frozen, switch-
ing the acquisition mode from TIMED to ENCODED
(or vice versa) will result in a loss of data. Data to be
retained must be stored in a data set prior to changing
the CLOCK setting. Similarly, selecting and altering
functions that require a recalculation of instrument
parameters will result in loss of unsaved TOP View
data.
NOTE: Pressing
below CLEAR, while the TOP
View is acquiring data in TIMED mode, immediately
eliminates all unsaved TOP View data and restarts
the display acquisition process. When the TOP View
display is STOPped (or frozen), pressing
below
START also eliminates all unsaved TOP View data and
restarts the display acquisition process. Pressing
below RESUME (if displayed) continues the acquisition
process from the point at which it was STOPped.
