The measurement Functions are fully
independent from one another. Information
(unless it is “stored”) is not retained when
switching from one Function mode to
another.
Auto Shutoff
The Digimet 3000 provides for automatic
shutoff of the unit after a user selectable
period of time from 0 to 30 minutes of non-
use. This is set in the Utility Menu, item
number eight. See section on Utility
Menu. This feature is designed to
maximize battery life. “Use” of the unit is
defined as presses on the front panel
keys. Each depression of a key will cause
an internal timer to reset to zero. This
timer is continually counting, and when it
reaches the specified time, the Digimet
3000 will shut off. When the Digimet 3000
is auto-shutoff, all currently displayed
information will be lost, the same as if a
user had switched the unit off. (Stored
data is not lost.) When the unit is auto-
shutoff and subsequently turned back on,
it will perform the normal start-up
sequence defined in the section entitled
Start-up Display.
Battery Low Indication
The Digimet 3000 detects when the
battery power is low and displays a
message. The Low Battery indicator is a
blinking “B” in upper right corner of the
screen. See more about the Battery Low
Indication under heading MENU &
DISPLAY SYSTEM.
Reset
The Vacuum Level Measurement function
has the ability to “reset” the Max. and Min.
Vacuum readings. Vacuum Level Min/Max
Reset is further discussed in the section
entitled Vacuum Level Function.
Data Display Hold
The Digimet 3000 has the capability to
“freeze” the data currently displayed, with
the use of the Hold mode. The entire set of
measurements for a Function that is held
will be frozen, including items not visible
within the display window. This allows the
user to scroll through all measurements.
When placed in Hold mode, the Digimet
3000 will continue to sample input and
calculate the measurements for the current
function; however, the display will not be
updated with the current information, but
will display the measurements at the time
the unit was placed in Hold mode. When
accessing the Option Menu to utilize Hold,
within a particular Function, the MENU key
must be pressed. The data that is on the
screen the instant the Menu key is pressed
will be the data held.
When the Digimet 3000 is then placed in
the Continue mode, the display will be
updated with current measurements. This
operation is analogous to a split-time
feature of a stopwatch. The Hold mode is
automatically released when the
measurement Function is exited. For
example, if the unit is in Hold mode within
