2 Installation
2.1 Receiving Inspection
Inspect all material received for shipping damage. Confirm that your shipment includes all material
and options ordered. If materials are missing or damaged, the carrier that made the delivery must be
notified within 15 days of delivery in accordance with Interstate Commerce regulations in order to
file a valid claim with the carrier.
2.1.1 Damaged Material
Any damaged material, including all containers and packaging, should be held for carrier
inspection. If your shipment is not correct for reasons other than shipping damage, contact our
Customer Service Department, 6450 Dry Creek Parkway, Longmont, Colorado 80503, phone
303-652-4400, email csr-co@brooks.com.
2.2 The Series 330 Vacuum Gauge Controller
The 330 Vacuum Gauge Controller (VGC) is provided with a single ionization gauge control. It can
be used to measure pressures from less than 1 x 10
-10
Torr (1.3 x 10
-10
mbar or 1.3 x 10
-8
pascal) to
1 x 10
-1
Torr using an ionization gauge; or from 1.0 x 10
-3
Torr (1.0 x 10
-3
mbar or 1.0 x 10
-1
pascal)
to 999 Torr using Convectron gauges, or from 1 x 10
-3
Torr to 1 Torr using thermocouple gauges.
Pressure ranges are air equivalent.
Pressure readout is via a front panel digital display for the ion gauge, and analog outputs for either
the Convectron gauges or thermocouple gauges.
The 330 VGC is a modular instrument with infrequently used controls housed behind a hinged front
panel, thus reducing front panel clutter and allowing the VGC to reside in a half-rack space.
2.2.1 Degas Function
The 330 VGC has a factory installed resistance heating degas option. An interlock is provided to
only allow degas when the ion gauge tube is ON and displayed pressure is below 5 x 10
-5
Torr.
Pressure reading during degas is not possible due to the I
2
R degas function.
2.2.2 Remote Input/Outputs
The VGC comes with a factory installed remote I/O option which provides an ionization gauge
relay status output, remote gauge on/off and remote degas on/off functions.
2.2.3 Analog Output Signals
Analog outputs for the ion gauge are provided for all controllers. Analog outputs for Convectron
gauge or thermocouple gauge options are covered in the respective chapters of this instruction
manual.
