2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the

appropriate dead-weight tester has been selected in terms of measuring

range, design and specic measuring conditions.

Non-observance can result in serious injury and/or damage to the

equipment.

Further important safety instructions can be found in the individual

chapters of these operating instructions.

2.1 Intended use

Pressure balances (dead-weight testers) are the most accurate instruments available

on the market for the calibration of electronic or mechanical pressure measuring

instruments. By direct measurement of the pressure as the quotient of force and area

(p = F/A), pressure balances (dead-weight testers) are approved as primary standards.

The core component of the CPB3800 is therefore a very precisely-manufactured piston-

cylinder system, onto which a mass load is applied in order to generate the individual

test points. The mass load applied are proportional to the target pressure and this is

achieved through graduated disc weight. A maximum pressure of 1,200 bar must not be

exceeded.

The pressure is set via an integrated, nely-adjustable, precision dual area spindle

pump. As soon as the measuring system reaches equilibrium, there is a balance of

forces between the pressure and the mass load applied.Then the test item can be

calibrated or adjustments can be carried out.

Due to its stand-alone operation (integrated pressure generation and the pure

mechanical measuring principle), the model CPB3800 is ideal for on-site use for

maintenance and service.

The instrument has been designed and built solely for the intended use described here,

and may only be used accordingly.

The technical specications contained in these operating instructions must be

observed. Improper handling or operation of the instrument outside of its technical

specications requires the instrument to be taken out of service immediately and

inspected by an authorised DH-Budenberg/WIKA service engineer.

2. Safety

Handle mechanical precision measuring instruments with the required care (protect

from humidity, impacts, strong magnetic elds, static electricity and extreme

temperatures, do not insert any objects into the instrument or its openings).

If the instrument is transported from a cold into a warm environment, the formation of

condensation may result in instrument malfunction. Before putting it back into operation,

wait for the instrument temperature and the room temperature to equalise.

The manufacturer shall not be liable for claims of any type based on operation contrary

to the intended use.

2.2 Personnel qualication

WARNING!

Risk of injury should qualication be insucient!

Improper handling can result in considerable injury and damage to

equipment.

■

The activities described in these operating instructions may only be

carried out by skilled personnel who have the qualications described

below.

■

Keep unqualied personnel away from hazardous areas.

Skilled personnel

Skilled personnel are understood to be personnel who, based on their technical training,

knowledge of measurement and control technology and on their experience and

knowledge of country-specic regulations, current standards and directives, are capable

of carrying out the work described and independently recognising potential hazards.

Special operating conditions require further appropriate knowledge, e.g. of aggressive

media.

DH-Budenebrg/WIKA can provide dedicated training courses on the correct use of our

products. Please contact your local oce for further details.

2.3 Personal protective equipment (P.P.E.)

The personal protective equipment is designed to protect the skilled personnel from

hazards that could impair their safety or health during work. When carrying out the

various tasks on and with the instrument, the skilled personnel must wear personal

protective equipment.

8

WIKA operating instructions model CPB3800

14062232.04 03/2015 EN/DE

EN

2. Safety

Follow the instructions, displayed in the work area, regarding personal

protective equipment!

The required personal protective equipment must be provided by the operating

company.

Wear safety goggles!

Protect eyes from ying particles and liquid splashes.

Wear protective gloves!

Protect hands from contact with aggressive media.

2.4 Special hazards

WARNING!

To ensure safe working on the instrument, the operating company must

ensure

■

that suitable rst-aid equipment is available and aid is provided

whenever required.

■

that the operating personnel are regularly instructed in all topics

regarding work safety, rst aid and environmental protection and

knows the operating instructions and, in particular, the safety

instructions contained therein.

WARNING!

Residual media at the dead-weight tester can result in a risk to persons,

the environment and the equipment. Take sucient precautionary

measures.

2.4.1 Mineral oils health and safety information

DH-Budenberg/WIKA provide hydraulic mineral oil in 500 ml containers labelled “ISO

VG 22” for use up to 4,000 bar in dead-weight testers. It is no more hazardous than other

common lubricating oils.

WIKA operating instructions model CPB3800

14062232.04 03/2015 EN/DE

2. Safety

It is the nature of the way in which this equipment is used, that there

could be frequent and/or prolonged skin contact; in a few individuals this

could give rise to skin irritation (Keratosis or Dermatitis). The use of an

eective barrier cream and/or protective gloves will greatly reduce this

possibility.

The main hazard following accidental ingestion is aspiration

of liquid into lungs.

Aspiration Send to hospital immediately

Inhalation Remove to fresh air, if nausea persists seek medical

attention.

Eye contact Wash with copious amounts of water for at least 10 minutes.

If irritation results or persists, obtain medical advice.

Skin contact Where skin rashes or other abnormalities occur as a result

of prolonged or repeated contact, medical advice should be

obtained as soon as possible.

Other liquids

The dead-weight tester model CPB3800 is manufactured for use on mineral oil only. If

an end user wishes to use it on another uid, it is the end user responsibility to ensure

that the uid is compatible with high tensile brass, stainless steel, mild steel, and nitrile

rubber, which are the materials that will come into contact with the uid.

Fluids, which attack ABS, should be used with caution. Continual

immersion of the cover in such uids will cause deterioration. Spillages

should be wiped o immediately.

Wear safety goggles!

Protect eyes from ying particles and liquid splashes.

Wear protective gloves!

Protect hands from contact with aggressive media.
