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 sys­tem in applications that may develop positive pressures. Positive pressures may cause the tube to

blown out of a compression fitting and damage equipment and injure personnel.

be

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 con­necting and disconnecting cables

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 propor­tional to the pressure.

For the CVT/Convection gauge, the 960 displays vacuum pre

ssure as meas

ured from a CVT-275
Convection Enhanced Pirani gauge tube. It displays vacuum measurements based on thermal con­ductivity of a gas. The 960 controller covers the range from 0.1 mTorr to 995 Torr,
995 mBar or 0.01 Pascal to 130 kPascal, 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

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.
