DVR-3000 Operation Manual
DVR Overview
This manual provides the necessary information for proper installation, operation, and maintenance of
the CANNON DVR-3000 Digital Vacuum Regulator.
DVR Function
The CANNON DVR-3000 instrument is designed to regulate vacuum at 300 mm Hg below atmospheric
pressure, at flow rates of up to 3 LPM. Vacuum may be adjusted to other settings, from 95–450 mm Hg.
The DVR is suitable for use with all CANNON temperature baths, including the CT and TE Series high and
low temperature baths.
Figure 1: DVR-3000
DVR Application
The DVR is ideal for use with Cannon-Manning calibrated CMVC series viscometers, Modified Koppers
Calibrated MKVC Series viscometers, Asphalt Institute Vacuum Calibrated AIVC series C Series
viscometers, and Asphalt Institute Vacuum Calibrated AIVC series viscometers for measurement of
highly viscous materials such as asphalt cement at 60 °C (140 °F) per ASTM D2171 specifications. Both
Cannon-Manning and Modified Koppers permit viscosity measurement from 42 to 200,000 poise.
Asphalt Institute AIVC Series 400R and 800R viscometers, also available from CANNON, extend that
range to 1,400,000 poise and 5,800,000 poise, respectively.
The DVR is also useful in other laboratory systems where accurate measurement and control of vacuum
from 95–450 mm Hg below atmospheric pressure is required.

If any part in this manual is not clear to understand or is missing articles, contact your local dealer or
sales representative.
The manufacturer is not liable for any loss or damage directly or indirectly caused by use of the
instrument or its consequences.
This manual pertains directly to the DVR-3000 Digital Vacuum Regulator. For details relating to other
accessories or equipment, please refer to the appropriate manufacturer-supplied documentation.
Safety Precautions
Always observe the following general safety precautions for proper and safe operation of the DVR-3000.
•Only qualified personnel should operate the DVR.
•Read and understand all operating instructions and safety precautions listed in this manual before
installing or operating the instrument. Contact Cannon Instrument Company with questions
regarding instrument operation or documentation.
•Do not deviate from the installation, operation, or maintenance procedures described in this
manual. Improper use of the DVR may result in a hazardous situation and may void the
manufacturer’s warranty.
•Handle and transport the unit with care. Sudden jolts or impacts may cause damage to
components.
•Position the instrument on a sturdy table or workbench.
•Provide at least 15 cm (6”) of ventilation space for the rear of the unit.
•Do not turn the power switch on and off rapidly and repeatedly.
•Observe all warning labels. Never remove warning labels.
•Never operate damaged or leaking equipment.
•Unless procedures specify otherwise, always turn off the unit and disconnect the MAINS cable
from the power source before performing service or maintenance procedures, accessing the
electronics drawer, or before moving the unit.
•Never operate the equipment with damaged MAINS power cables.
•Refer all service and repairs to qualified personnel.
Warning: Always ensure the protective ground (earth) terminals of the
instrument connect to a protective conductor of the MAINS
power cord. Use only the manufacturer-supplied power cord,
and do not use an extension cord without protective grounding.

Tubing Connections
Tubing connections for the DVR-3000 may be arranged in a variety of ways to suit application and
environment. Make sure that there is adequate slack in the tubing to avoid kinks in the line (kinks
prevent optimal control).
Connect to Your Application
DVR-3000 features an international standard G1/8 parallel port on the front of the unit. A simple push fit
can be made with a rubber hose; alternatives may be fitted by simply unscrewing the fitting.
1. Connect the DVR-3000 to your vacuum manifold or application using the 4' (122 cm) length
rubber vacuum tubing provided by CANNON. Secure the tubing to the Vacuum Manifold Inlet on
the front panel of the DVR. Refer to Figure 2.
2. Push the tubing firmly into place over the barbed nipple fitting.
3. Attach the other end of the tube to your manifold/application, clamping the connection if
necessary.
4. Check all vacuum connections to make sure they are secure.

Vacuum Trap
An integral vacuum trap is provided on the front of the DVR-3000 and is designed to prevent liquids
from being pulled into the system and damaging the internal components.
The trap can only “catch” about 20 mL of fluid; it is not suitable for use as a reservoir or waste
receptacle. In the event a small amount of fluid enters the vacuum system, perform the following:
1. Immediately power OFF the unit.
2. Unscrew the hand-tight ring on the front to empty the chamber.
3. Clean the connecting rubber tubing with appropriate solvent(s).
4. Thoroughly dry the tubing before reconnecting it to the DVR.
Electrical Connections
After vacuum tubing is successfully connected, use the MAINS power cord provided with the DVR to
supply electricity to the unit.
Caution: Avoid pulling liquid solvent past the vacuum trap as this may cause
internal damage to DVR components and create a safety hazard.
Caution: The main plug for the power cord should only be inserted in a socket
outlet or receptacle provided with a protective ground (earth) contact.
Do NOT use an extension cord/power cable without a protective
conductor (grounding).

The ~MAINS symbol indicates instructions or connections for the AC power supply. The AC Power input
must match the electrical specifications listed on the label on the rear panel of the instrument. The
supplied AC MAINS power cord must attach to the connector labelled ~MAINS. This connection serves as
a means of disconnect and should be readily accessible.
The (O) symbol indicates the OFF position for the electrical switches for the unit (AC Mains or
accessories).
Connecting Power Cable
1. Plug the power cord into the DVR rear panel IEC Power Inlet connector. See Figure 3.
2. Plug the other end of the cord into an appropriate electrical outlet.
