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 specic 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 specications contained in these operating instructions must be
observed. Improper handling or operation of the instrument outside of its technical
specications 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 qualication
WARNING!
Risk of injury should qualication be insucient!
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 qualications described
below.
■
Keep unqualied 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-specic 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 oce 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.

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 sucient 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.

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
eective barrier cream and/or protective gloves will greatly reduce this
possibility.
