• A “1” will appear in the tens place (third digit
from the right), which will immediately begin to
increment by a count of “1.” It will do this until it
cycles from “9” back to “0,” at which point…
• A “1” will appear in the hundreds place (fourth
digit from the right), which will immediately
begin to increment by a count of “1.” The first
time it cycles from “9” back to “0,”…
• A “1” will appear in the thousands place (fifth
digit from the right).
The fifth digit from the right would behave simi-
larly, if you needed to increase the displayed
number to the order of
ten thousand. Note,
however, that the only nonzero value the
sixth
digit from the right can ever have is “1” (see
Section 1.D).
Because the digits change rapidly,
it’s easy to
overshoot a target digit value
. Therefore, when
you’re getting near that value, it’s best to release
the button momentarily—
not longer than 2
seconds
—and then repeat pressing the button
rapidly without holding it down
until you get to the
target digit value. If you hold the “re-pressed” but-
ton down longer than two seconds, the increment-
ing (or decrementing) process
will go back to the
least significant digit (LSD)
.
Of course, you can correct an
upward overshoot
for a given digit by pressing the
DOWN button, but
you must do so within 2 seconds of releasing the
UP button.
If you release the
UP button and wait more than 2
seconds
before pressing it again (or pressing the
DOWN button), the incrementing (or decrementing)
process
will go back to the least significant digit
(LSD)
—as we want it to do in Steps 2-4.
In the above example of a target number of
“1230.8,” you could prevent upward overshoot by
momentarily releasing the
UP button as soon as
“7” appears in the
hundreds place. You would then
immediately press it rapidly three more times to get
the desired “1” in the
thousands place.
2. When you have a “1” in the thousands place,
release the
UP button, wait at least 2 seconds, and
press and hold it again. The LSD will again begin to
increment by the present “count” value. This time
you will press and hold down the
UP button until a
“2” appears in the
hundreds place (fourth digit from
the right).
3. Wait at least 2 seconds, and then press and hold
down the
UP button until a “3” appears in the tens
place (third digit from the right).
4. Wait at least 2 seconds, and then press and hold
down the
UP button until the LSD reaches “8.” The
ones digit (second from the right) need not be
changed from its present value of “0.”
NOTE: As the number being increased or decreased
crosses zero, its sign will immediately change. It
doesn’t matter which particular digit you are in the
process of incrementing or decrementing; as soon as
the value of the displayed number (as a whole) passes
through zero, the sign change will occur. The digit that
was active before the sign change will still be active
(and will continue to increase or decrease) after the
sign change. For example, you might see the following
sequence of displays, as the fourth digit from the right
is being decremented by holding down the
DOWN but-
ton:
3000
2000
1000
0
-1000
-2000
-3000
VIEW ONLY MODE
In “VIEW ONLY” mode, the front-panel SCROLL and
UP/DOWN buttons are disabled, so that the operator
can sequentially
display all values within the
3000PLUS’s current setup configuration
without being
able to change any of them
(the only exception is the
instrument’s
SECURITY CODE, which will not be dis-
played in VIEW ONLY mode).
For entering VIEW ONLY mode, see Section 3.B, Steps
1.a through 1.d.
STEPPING THROUGH THE SETUP STAGES
By repeatedly pressing
you can quickly advance through the successive
“stages” of the setup sequence (
SETUP, RANGE, FIL-
TER
, etc., as announced by the front-panel indicator
lights—see Fig. 2 and Section 1.D). Within each stage,
is used (as explained above) to step through the para-
meters of that stage. Remember that
