5.2.2 Supply Port
The pressure supplied to the pressure connection labeled “Supply” should be approximately the greater of 30 ... 50 bar (435 ... 725
psi) or 7-10% higher than the full scale of the highest pressure transducer installed in the controller.
5.2.3 VENT PROP Port
The pressure connection labeled “VENT PROP” is the port where the system pressure is vented to the atmosphere under certain
conditions. Leave this port as is.
5.2.4 VENT NO Port
The pressure connection labeled “Vent NO” is the port where the system pressure is vented to the atmosphere under emergent
conditions. Leave this port as is.
5.2.5 Measure / Control Port
The Measure / Control port (when in the Control mode) supplies pressure that is precisely controlled by the controller. In the
Measure mode, a pressure applied to the Measure / Control port is measured by the internal transducers.
5.2.6 Vent Ref Port
The pressure connection labeled “Vent Ref” is the port where the not in use reference transducer pressure is vented to the
atmosphere under certain conditions. Leave this port as is.
5.2.7 Barometric Reference Port
The barometric references port is available on gauge units that have transducers that are not sealed gauge units. For these units
this port is available to connect to the reference side of the transducer. This port is normally left open to atmosphere but may be
connected to a stable reference pressure. In an absolute pressure transducer this port is not used
5.2.8 Optional: Barometric Sensor Port
The Barometric Sensor port is connected to the optional internal barometer and should be left open to atmospheric pressure.
5.2.9 Remote Communication Connections
See Section 8, Remote Operation for connections and commands for operation over IEEE-488, Ethernet, USB or RS-232 ports.
5.2.10 Power Up
Apply power to the power connector on the rear of the instrument using the power adaptor included, and switch the power switch
on the front of the unit ON. The instrument will go through an initialization process and system check. As soon as the system check
is completed the system will default to a screen similar to the one shown in Section 6.1.2, Display Screen Features. The main
measurement screen may be configured in many different ways but initially it will be in a default configuration. Subsequently, the
unit will power up in the configuration that it was in when last powered off. Allow at least 15 minutes of warm up before performing
critical pressure measurements
.
Do not position the equipment so that it is difficult to remove the power cord. The instrument is not intended for
connection of long-distance lines, i.e. lines within a building that are longer than 30 m, or that leave the building
(including lines of outdoor installations).
