Page 7: Safety Precautions
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. -

Page 10: Dvr Overview
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. -
Page 11: Dvr-1000 Vs. Dvr-1500
The DVR is available from CANNON in both horizontal and vertical configurations. With its sturdy steel construction, the horizontal DVR unit is able to support any CANNON CT or TE Series temperature bath. The vertical or horizontal configuration offers convenience in locations where workspace is at a premium. -

The (O) symbol indicates the OFF position for the electrical switches for the unit (AC Mains or accessories). Connecting Power Cable Make sure that the 3-position switch on the front panel is set to the center STANDBY position. Plug the power cord into the DVR rear panel IEC Power Inlet connector. Plug the other end of the cord into an appropriate electrical outlet. -
Page 16: Dvr Operation
Points. Accessories TheThe DVR is designed for use in conjunction with the CANNON 3VM and 4VM vacuum manifolds. The 3VM manifold (part number 9726-V10) has three valves and pairs with the CANNON CT-500 Series Constant Temperature Bath. The 4VM manifold (part number 9726-V05) has four valves and pairs with the CANNON CT-1000 Series and CT-2000 Series Constant Temperature Baths. -
Page 17: Meter Display/Key Control Options
The DVR’s vacuum is regulated by two solenoid valves mounted inside the unit. The valves operate in tandem to maintain consistent vacuum at the desired setting. CANNON creates preset control set points for the solenoid valves to regulate vacuum at 300 mm Hg below atmospheric pressure. If it is necessary to adjust these settings, see section Altering Factory Settings. -
Page 18: Bleeding Vacuum
This action disengages solenoid operation for both models and turns off the DVR-1500 vacuum pump. CANNON advises users bleed off residual DVR system vacuum to 250 mm or lower when the instrument is in the center STANDBY position. This prevents the unit from overshooting the target vacuum (default 300 mm Hg) when the toggle switch is returned to the RUN position. -

Page 20: Selecting Set Point Values
Once your control point (desired vacuum setting) is known, you must select and test new set points. Normal factory set points may provide a useful reference. The unit is shipped from CANNON with a value of 292.5 mm Hg for LO and a value of 299.6 mm Hg for HI. These settings allow the DVR to control at 300 mm Hg ±... -
