moisture or liquids, but care should be
taken to prevent this from happening.
If, for example, milk were allowed to
enter the transducer and dry, the
performance of the transducer could be
affected. A filter is provided to keep liquids
from coming into contact with the
transducer. IMPORTANT: THE FILTER
MUST BE USED AT ALL TIMES.
If milk accidentally enters the transducer
area, the transducer should be rinsed with
water. Please refer to the section
Cleaning for further instructions. If milk is
allowed to dry inside the transducer, the
transducer will need to be replaced.
The Acrodisc filter will not allow milk to
pass through it. As long as milk is not
allowed to sit in the filter, milk will not
adhere to the filter membrane. Keeping the
filter clean will allow for repeated use.
Check the filter periodically to determine
whether it has become plugged or
restricted. To do this, check Digimet 3000
readings on one of the pulsation (vacuum)
Functions with and without the filter in
place. If similar readings are obtained then
the filter is not plugged.
The tube that comes out of the Digimet
3000 at the port labeled VACUUM is
connected to a quick-disconnect male
fitting (DM3-16-03). When the Digimet is
not in use, a white plug (DM3-16-06) plugs
the opening of the male fitting. When in
use, attach the Acrodisc filter (DM3-15) to
the male fitting and TIGHTEN. Attach to
the Acrodisc filter a 4’ length of 5/32”
plastic tubing which is used to connect the
Digimet 3000 to the vacuum system. Note:
the 5/32” tubing has a small tube clamp on
the end that connects to the Acrodisc. This
provides for a tighter fit to the smaller 1/8”
slip-fit end of the Acrodisc.
Three methods can be used to connect the
Electronic Pulsator Input
The DIGIMET 3000 has two banana jack
receptacles located on the front panel.
These jacks are located side-by-side with
a distance between them that
accommodates a standard 3/4" double
banana plug or single plugs as provided
with the unit. THE UNIT WILL FUNCTION
PROPERLY WITH EITHER POLARITY
OF INPUT.
RS-232 Serial Port (9-Pin)
This 9-pin serial connector is used to
connect the Digimet 3000 to either the
Digimet Printer or a computer. Cables are
provided. The serial port has a small
plastic dust cover for protection. This port
is labeled Serial.
Carrying Case – Standard
The DIGIMET 3000 padded canvas
carrying case is approximately 9" long x 5"
wide x 3 1/2" deep. Case includes a
compartment for the DIGIMET 3000 with
two inside straps to keep the unit in place,
and an additional compartment for storing
items such as vacuum tubing, banana
plugs, extra batteries, etc. A shoulder strap
is also provided.
Large Carrying Case
The Large Hard Carrying Case is
approximately 15-3/4” x 9-7/8” x 6-7/8”. It
is divided into compartments which
tubing to the vacuum system: 1) A needle
connector and stainless steel needle. Be
sure needle does not become plugged
during use. (See the section Use of
stainless needle.) 2. A “T” fitting is
supplied to accommodate plugging into
the short pulsation air tube without use of
a needle. 3) A 1/4” plastic pipe fitting with
a 5/32” nipple is also provided to tap into
plastic pipe systems, as well as a plastic
pipe plug to be used when the fitting is
