accommodate the Digimet 3000, the
Digimet Printer, AC wall transformer (for
the printer) and accessories. A shoulder
strap is also provided.
Fittings Supplied with DIGIMET 3000
The Digimet can accommodate two types
of input: 1) vacuum; 2) electrical
pulsation. Fittings are supplied to facilitate
both forms of input.
Vacuum Port – The vacuum port is labeled
VACUUM and consists of a quick-
disconnect male luer fitting (DM3-16-03)
with a white plug (DM3-16-06) attached.
The white plug serves as prevention
against debris entering the vacuum port
when the unit is not in use. A quick
counter-clockwise turn will remove the
white plug from the male luer fitting.
During operation, the vacuum port with its
male luer fitting is attached to an Acrodisc
filter (DM3-15) which is connected to
approximately 4' of 5/32" tubing. A small
hose clamp is provided to secure the hose
to the Acrodisc filter, tightly. Note: the
Acrodisc filters should be used at all
times. To connect the free end of the
tubing to the vacuum system, the user has
several choices: 1) A needle connector
(DM3-Connector) is provided for use with
the stainless needle (DM3-17), which is
inserted into rubber components of the
milking system. (See section
Miscellaneous-Use of stainless needle.)
2) 5/32" nipples may be fitted into the
vacuum system for connecting the 5/32"
tubing. A sample of such a fitting is
provided with your Digimet 3000 (pipe
fitting DM3-PIPE and plug DM3-17-02).
The pipe fitting is a 5/32-27 NPT fitting.
See the section, Tapping holes, for
instructions on tapping holes for this fitting.
3) A pulsator tube adapter “T” fitting
(provided) can be used to check pulsation
line vacuum instead of using the stainless
needle. Connect opposing sides of the “T”
fitting to the short pulsation air tube at the
milk claw and the middle of the “T” to the
Digimet 3000 plastic tubing.
SPECIFICATIONS
This section defines the operating
conditions and performance specifications
which apply to the Digimet 3000.
Power
The Digimet 3000 operates on four AA
alkaline batteries. The Digimet 3000 will
operate for approximately 40 hours before
batteries need to be changed. When the
batteries are low, in the upper right-hand
corner, a “B” will blink, indicating low
battery level. The unit will still function but
the batteries should be replaced. If the
batteries are not supplying sufficient power
for the unit to function properly then the
screen will go blank and the unit will turn
itself off. The battery compartment is
located just behind the LCD display with
the opening on the back side of the unit.
Care should be taken to install batteries
in the proper direction. Data stored in
the Digimet is not affected by turning the
unit off. If the batteries are replaced,
however, they should be replaced within
an hour of removal or storage data will
be lost.
Vacuum Input
In this manual, VACUUM refers to a
differential pressure, with atmospheric
pressure as the reference. Zero vacuum
equates to a zero difference from
atmospheric pressure. Positively
increasing vacuum equates to a
decreasing of pressure relative to
atmospheric pressure (i.e. less than
atmospheric pressure).
