3. Safety
3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury
or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries
or damage to property or the environment, if not avoided.
EN
Information
... points out useful tips, recommendations and information for efficient and
trouble-free operation.
3.2 Intended use
This CPH6300 hand-held pressure indicator can be used as a calibration instrument and
also for any application which requires high-accuracy pressure measurement.
This instrument is not permitted to be used in hazardous areas!
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
Improper handling or operation of the instrument outside of its technical specifications
requires the instrument to be taken out of service immediately and inspected by an
authorised WIKA service engineer.

3. Safety
Handle electronic precision measuring instruments with the required care (protect from
humidity, impacts, strong magnetic fields, static electricity and extreme temperatures,
do not insert any objects into the instrument or its openings). Plugs and sockets must be
protected from contamination.
EN
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.
3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
▶
Refrain from unauthorised modifications to the instrument.
▶
Do not use the instrument within hazardous areas.
▶
Do not use the instrument with abrasive or viscous media.
▶
Observe the working conditions in accordance with chapter
9 “Specifications”.
▶
Always operate the instrument within its overload limits.
Any use beyond or different to the intended use is considered as improper use.
3.4 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient
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 qualifications described
below.
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who,

3. Safety / 4. Transport, packaging and storage
This marking on the instruments indicates that they must not be disposed of
in domestic waste. The disposal is carried out by return to the manufacturer
or by the corresponding municipal authorities.
EN
4. Transport, packaging and storage
4.1 Transport
Check the model CPH6300 hand-held pressure indicator and the model CPT6200
reference pressure sensor for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during internal
transport, proceed carefully and observe the symbols on the packaging.
▶
With internal transport, observe the instructions in chapter 4.2 “Packaging
and storage”.
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.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: -25 ... +70 °C (-13 ... +158 °F)
■
Humidity: 0 ... 95 % relative humidity (non-condensing)
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Hazardous environments, flammable atmospheres

consumption.
Measuring rate > 1,000 Hz; the value is displayed unfiltered.
Field of application in combination with logger function:
Measurement of pressure spikes or fluctuating pressures with a

mean value, the highest and the lowest peak during the chosen time
interval.

5.4.3 Sea level correction for absolute pressure sensors
The CPH6300 measures the absolute pressure of the ambient air. This is not to be
confused with the “air pressure at sea level” given by the weather station! With this
pressure indication, the altitude-dependent atmospheric pressure drop is calculated.
The instrument is capable of making this air pressure altitude correction.
1. For this, activate the “Sea level function” (see chapter 5.3 “Configuration of the
instrument”).
The setting is only possible, if an abs. pressure sensor is connected to sensor

displays the absolute pressure at sea level.

Function of Min/Max value memory in conjunction with the averaging function:
■
If averaging is activated and slow measuring, rAtE SLo, is selected, the min/max
memory value relates to the average display value.
■
If averaging is activated and fast measuring function is selected (rAtE FASt
or
P.dEt), the min/max memory value relates to the internal measured values
(> 1,000 Hz measuring frequency).

Manual recording of the measured value by pressing the [STORE/

Fvnc CYCL
Automatic recording at the interval of the set cycle time.
1-channel version:
The data logger displays 3 measuring results for each data set:
■
CALC off: Measured or mean value (depending on function), Min.-Peak and
Max.-Peak
■
CALC “active”: Measured or mean value (depending on function)

Min.- and Max.-Peak are, respectively, the minimum and the maximum measured value
during the last save operation. Therefore both the current pressure value and also any
pressure spikes occurring can be accurately analysed.

recording, a measurement only occurs at the respective logger time. This
