Safety Precautions
Always observe these signs and instructions. Observe cautionary messages and warnings in order to
protect yourself and prevent others from physical injury or property damage.
CANNON advises turning OFF the vacuum source when changing DVR meter settings. For the DVR-1000,
it is necessary to disconnect the connection to the in-house vacuum source or turn the vacuum off. For
the DVR-1500 unit, which includes a built-in vacuum pump, the vacuum can be shut off by switching the
DVR front panel switch to the METER position. Turning off the vacuum prevents vacuum from building
up while altering the meter gauge settings.
•Only qualified personnel should operate 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.

DVR Function
The CANNON DVR 1000 Series instrument is designed to regulate vacuum at 300 mm Hg below
atmospheric pressure. Vacuum may be adjusted to other settings, from 28 mm Hg to 411 mm Hg. The
DVR is suitable for use with all CANNON temperature baths, including the CT and TE Series high and low
temperature baths.

DVR Application
The DVR is ideal for use with the Cannon-Manning calibrated CMVC series viscometers, the Modified
Koppers Calibrated MKVC Series viscometers, and the Asphalt Institute Vacuum Calibrated AIVC series C
Series viscometers, and the 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 the Cannon-Manning and the Modified Koppers permit viscosity measurement from
