Safety Information
Explosive Gases and Solvents
WARNING!
Do not use the Model 960 Dual-Hybrid Gauge Controller to measure the pressure of combustible
gas or solvent mixtures. The Convection gauge normally operates at low temperatures, but it is
possible that momentary transients or controller malfunction may cause ignition of combustible
mixtures, which then might explode and cause damage to equipment and injury to personnel.
Limitation on use of Compression Mounts
WARNING!
Do not use a compression mount (quick-connect) for attaching the gauge tube to the vacuum sys-
tem in applications that may develop positive pressures. Positive pressures may cause the tube to
be blown out of a compression fitting and damage equipment and injure personnel.
Caution - High Voltage
The Terranova Model 960 and the 525 Cold Cathode Gauge (CCG) operate at
High Voltage. The High Voltage of -2,000 volts can be dangerous to equipment
and personnel if exposed and contacted. Connectors and cables protected and
normally safe, but care must be exercised. Always turn power OFF prior to con-
necting and disconnecting cables.
Please let us Know...
Terranova products are the most advanced instruments of their type available from any
manufacturer. We have made this Instruction Manual as complete and clear as possible.
Let us know if you have any comments that can make this manual or our products more
useful.

B. General Description
The Terranova Model 960 CVT-CCG Vacuum Controller displays vacuum pressure as measured
from both a Cold Cathode gauge (CCG) and a Convection Enhanced Pirani (CVT) gauge. The
960 is housed in a 1/8 DIN enclosure and is simple to operate.
For the CCG, the 960 supplies -2000 VDC and senses/displays the ion current, which is propor-
tional to the pressure.
For the CVT/Convection gauge, the 960 displays vacuum pressure as measured from a CVT-275
Convection Enhanced Pirani gauge tube. It displays vacuum measurements based on thermal con-
ductivity of a gas. The 960 controller covers the range from 0.1 mTorr to 995 Torr, 0.1 µBar to
995 mBar or 0.01 Pascal to 130 kPascal, user selectable.
C. Specifications

higher than 995 Torr (mBar) or no tube attached to cable, display HI; if cable is not connected to
the unit, display shows OFF
3. Input to the 960 Controller
CCG:
Ion current is measured in the HV supply
CVT
Pressure is calculated from the gauge output according to gauge supplier’s algorithm, confor-
mance to published data is typically within +/- 1%.
4. Units of Display
For both CCG and CVT:
Torr, mBar, Pascal, user selectable

14. Mounting
The 960 may be used as a bench-top instrument or it may be mounted in an instrument panel.
Clips are provided for panel mounting.
15. RS-232 Input/Output
allows user to read pressure, set points and other parameters; 9600 baud, 8-N-1; available through
the accessory connector
16. Operating Voltage
The Model 960 has a universal power supply, which operates on input voltages from 90 VAC to
240 VAC 47 to 65 Hz; input is through a power input receptacle on the rear panel.
17. Fuses
Input power is protected by internal, self-resetting, fuses in both lines of the input power. When
the input current exceeds 2 amps for 25 seconds, the fuses open. After 30 seconds open, the fuses
re-set to closed.
18. Weight, Model 960 only; does not include cable or CVT and CCG tubes

II Installation
A. Unpack the Controller
Carefully unpack the Model 960 Dual - Hybrid Vacuum Gauge Controller. The shipment includes
these components:
• controller unit
• power cord
• mounting clips
• D-sub 15 accessory connector
• this instruction manual
If your controller does not have all of these items, call Duniway Stockroom. If anything appears
to have been damaged in shipment, contact the shipper.
B. Mount the Controller
You can rest the controller unit on a bench, table top, or shelf, or you can mount it in a rack or
cabinet. The controller unit is housed in a standard 1/8 DIN box. If you are mounting the unit in
a panel, the cutout dimensions are 1.78 inch by 3.60 inch (45.2 mm by 91.4 mm), see fig. 3, page
9. One mounting clip attaches to each of the sides of the controller unit. To attach the clip, slide
the beveled surfaces of the clip under the cutout on the side of the box and push the clip toward
the back of the unit.
Be sure to leave enough clearance at the back of the controller unit for easy access to cable con-
nections and enough space around the vents of the unit to allow heated air to escape.
C. Select the CCG
The Model 960 controller is designed to work with the Duniway CCG-525 and Varian Model 525
Cold Cathode gauges.
D. Select the CVT Tube
The Model 960 controller is designed to work with the CVT-275 or the
Brooks/Helix/Granville-Phillips type 275 Convectron®sensor tubes, both of which are supplied
by Duniway Stockroom Corp.
