PRODUCT DESCRIPTION The Rosemount Model P330 Pressure Validator is a rugged and
portable precision validator available either in a pneumatic or a
hydraulic version. It is used primarily for validating transmitters and
systems over the range of –15 to 300 psi (–1 to 20 bar), HAV version to
6,000 psi (400 bar). Used in conjunction with external transducers, the
range of the standard validator can be extended up to 10,300 psi (700
bar).
The validator can power an external current loop to a maximum output
current of 25 mA, and measure dc voltages of ±50 V and dc currents of
±55 mA. It can also measure ambient temperature.
The validator is powered by a rechargeable NiCad battery pack. It can
also be powered by six alkaline C cell batteries.
The validator also has an RS232 interface to download datalog files to a
computer.
SAFETY MESSAGES Procedures and instructions in this manual may require special
precautions to avoid damage to equipment and to ensure the safety of
the personnel performing the operations. Refer to the safety messages
listed at the beginning of each section before performing any
operations.

2Hardware Controls and
Connections
OVERVIEW This section describes the power, pressure, and electrical controls of the
Model P330 Pressure Validator. Power sources and powering
procedures, pressure controls and the pressure-generation procedure,
and electrical controls, including a section on test leads, are described
in this section.
SAFETY MESSAGES Procedures and instructions in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated
by a warning symbol ( ). Refer to the following safety messages before
performing an operation preceded by this symbol.
Warnings ( )
POWERING THE
VALIDATOR The validator can be powered by three sources:
• A rechargeable NiCad battery pack
• An ac power adapter/charger unit
• Six alkaline C cell batteries
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and the terminals.
Validator housing could explode causing death or serious injury.
• This Validator is not to be connected to a process.
• External pressure source’s pressures should not exceed the Validator’s Burst
Pressure.
Exposure to pressure leaks can cause death or serious injury.
• Ensure that all pipes and fittings are correctly rated for the operating pressure
and temperature.
• Remove pressure and vent the transmitter, validator, and all lines before
disconnecting any pressure lines.
• Remove pressure and open the vent valve before switching the pressure/vacuum
output, if the validator is equipped with one.

NOTE
Old batteries can leak and cause corrosion. Never leave discharged
batteries in the validator.
NOTE
If a rechargeable battery pack is installed and the display reads
BATTERY LOW,you must charge the batteries before use.
NOTE
Zinc-carbon and zinc-chloride cells are not recommended for this
validator. These types of batteries may cause unsatisfactory
performance. Use alkaline batteries.
NOTE
Press the SETUP key to see the battery level.
Installing Batteries To install batteries, refer to Figure 2-1 and follow the steps below.

Hardware Functions
To install either the rechargeable NiCad pack or six C cell batteries,
proceed as follows:
1. Ensure that the validator is turned off.
2. Unscrew the battery compartment cover and remove it.
3. If there are batteries in the compartment, carefully lift them out.
4. Fit new batteries or a battery pack into the compartment aligned
as shown in Figure 2-1.
5. Replace the cover and tighten the screws.
Charging theNiCad Battery
Pack To charge the NiCad battery pack, proceed as follows:
1. Plug the ac power adapter/charger unit into the dc power input on
the external interface panel (see Figure 2-4 on page 2-7).
2. Plug the ac power adapter/charger unit into an ac power supply.
3. Turn the validator on, and let it charge for 14 hours for a fully
recharged battery.
See Safety Messages on page 2-1 for complete warning information.

NOTE
The validator must be powered on in order to charge. The validator may
be operated while in charging mode.
PRESSURE CONTROLS The pressure controls are used to generate and control pressure during
pressure validations. Pressure controls are shown in Figure 2-2 and
described in Table 2-1.
The validator is not equipped with a connector for the pressure port. A
1/8–27 NPT coupling and a lead tube with the correct coupling for the
transmitter are required to properly generate a pressure.

PRESSURE-GENERATION
PROCEDURE The pressure-generation procedure is provided in all validation testing
procedures. It allows you to become acquainted with the features,
processes, and safety considerations involved with validation testing.
Before performing any validation procedures, read the following
pressure safety notes carefully.
NOTE
The pressure test port has a 1/8–27 NPT female coupling. The coupling
hose to the transmitter being tested must fit this specification.
Pressure-Generation Procedure
1. Ensure that the validator is turned off.
2. Open the release valve on the validator.
3. While the vent is open, set the pressure/vacuum knob to + or – as
required.
4. Connect the transmitter to the reference pressure port on the
validator using a 1/8–27 NPT coupling device and a pneumatic
hose. Use proper materials.
5. Close the release valve.
6. Perform the validation test per individual validation instructions.
7. Open the release valve to release pressure before disconnecting.

CONNECTIONS Before performing any validation procedures, read these electrical
safety messages carefully.
NOTE
Do not exceed these maximum input limits:
Voltage: 50 V dc
Current: 55 mA dc
NOTE
Use the test leads provided or correctly terminated wires to make
connections to the 4 mm input/output sockets. Do not push bare wires
into the sockets. For EMC compliance, use the provided test leads only.
Electrical connections consist of validation connections and external
interface connections.
•Validation connections sockets: used for hookups to
transmitters being tested. Located on the validator control panel.
•External interface connections: used for connecting with
external devices. The external interface panel is located on the
front end of the validator and contains the ac power adapter port,
the RS232 port, and the external transducer (also called the
remote sensor) port.
See Safety Messages on page 2-1 for complete warning information.

Validation Connections The validation connections are located on the validator control panel.
Use these sockets to make electrical connections to the transmitter
being tested. Figure 2-3 shows the validation connections.
External Power vs. Validator
Power If the transmitter is in an existing power loop, it is said to be
“externally powered.” If the transmitter needs to be powered by the
validator’s 24 V power supply, it is said to “validator powered.”
Connection diagrams are provided for both procedures where
applicable. Ensure that the correct settings are selected on the
validator for each test procedure.
Electrical Test Leads The validator is equipped with four test leads for validation testing. Use
the test leads as follows:
• The red test lead connects to the positive (+) connection on the
validator and transmitter.
• The black test lead connects to the negative (–) connection on the
validator and transmitter.
• The blue and the green test leads are not polarity sensitive and
can be used for either positive or negative connections.

Hardware Functions
Interface Connections The interface connections are on the back or top of the validator. They
are the external transducer port, the RS232 port, and the dc input port.
See Figure 2-4 for a diagram and Table 2-2 for a description of the
external interface connections.
TABLE 2-2. Interface Connections.
CHANGING FUSES The Model P330 Pressure Validator is equipped with internal fuses that
can only be changed by your distributor.
ADDING AN EXTERNAL
SENSOR (TRANSDUCER) NOTE
Before using an external sensor for any measurements, a two-point
calibration must be carried out.
To add an external sensor (transducer), proceed as follows:
1. Make sure the validator is off.
2. Connect the external sensor to the EXT TRANS port at the back of
the validator.
3. Connect the pneumatic end of the sensor to the pressure source,
e.g., hand pump.
4. Turn on the validator.
5. Select your test from the basic or advanced mode.
6. Perform a two-point calibration of the sensor if it is a new sensor.
See Appendix A Calibration for instructions on accessing menu
options for this procedure.
