2.1 Intended use
The Hand-Held pressure indicator CPH6300 gauge can be used as a calibration instrument and
also for any application which requires accuracy pressure measurement.
The Hand-Held pressure indicator CPH6300 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 Hand-Held pressure indicator CPH6300 outside of its
technical specifications requires the instrument to be shut down immediately and inspected by an
authorised WIKA service engineer.
Handle electronic precision measuring instruments with the required care (protect from 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.
If the Hand-Held pressure indicator CPH6300 is transported from a cold into a warm environment,
the formation of condensation may result in the instrument malfunctioning. 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.

2.3 Special hazards
WARNING!
■If it is obvious that safe operation of the instrument is no longer possible, the
instrument must be put out of operation and marked in order to secure it against
inadvertent use.
■The measurement signal of the reference (or test sample) can be influenced by
massive electromagnetic irradiation and/or the indication of the signal could be
completely absent.
■If the Hand-Held pressure indicator CPH6300 is used in applications with oil as
a pressure medium, make sure it will not be used with flammable material or
gases directly afterwards since it can lead to dangerous explosions and danger
to personnel and machinery.
■Pressure sensor CPT6200 should only be fitted or removed when the system is
free from pressure.
■Observe the working conditions in accordance with chapter “3. Specifications”.
■Always operate the pressure indicator within its overload limits.
■This device must not be used at potentially explosive areas! The usage of this
device at potentially explosive areas increases danger of deflagration, explosion
or fire due to sparking.
■When connecting the device to other devices the connection has to be designed
most thoroughly as internal connections in third-party devices (e.g. connection
GND with protective earth) may lead to undesired voltage potentials that can
lead to malfunctions or destroying of the CPH6300 and the connected devices.

6.4 Special Features
6.4.1 Different Pressure Units
Depending on the connected sensors different units can be selected via menu (Unit). The
measuring range of the sensors may restrict the choice!
User-Unit
For pressure units, which are not covered by the ones printed on the display, there can be done a
manual setting for a “user-defined” unit.
Example:
To enable a reference pressure sensor CPT6200 to display the unit kg/cm2, following settings
(bold) have to be entered:
kg/cm2

6.4.2 Different measuring rates
Three different kinds of pressure measuring are supported. Two of them (P.dEt and FASt) are
working with high measuring frequency of more than 1000 measurings per second.
6.4.2.1 Standard measuring (slow)
Measuring rate 4 Hz, averaging and filter functions are active.
Application: Measuring of slowly changing or static pressures, e.g. leak testing,
atmospheric pressure, etc.
Highest accuracy, high noise immunity, low power consumption.
6.4.2.2 Peak detection (Peak detection)
Measuring rate >1000 Hz, the value is displayed unfiltered.
Application with logger function: Measuring of short pressure peaks or fast changing
pressures with a resolution of <1 ms. The cyclic logger function records the arithmetic
mean value, the highest and the lowest peak of the referring time interval.
This measuring is sensitive to noise (EMI, ...) and power consumption is
enhanced.
6.4.2.3 Fast filtered measuring (fast)
Measuring rate >1000 Hz, but the value is filtered (higher noise immunity than P.dEt,
short peaks will be filtered out), apart from that identical behavior like rAtE-P.dEt.

14043054.01 07/2012 GB/D
6.4.3 Sea-level correction for absolute pressure sensors
The device displays the absolute pressure. This is not necessarily the same like the values given
by weather stations! The weather stations are displaying the pressure at sea level. Usually the
sensor is placed above sea level and therefore the pressure loss resulting from the actual level
above sea level has to be considered, if the value at sea level (zero) should be measured! To
correct the measuring display, activate the “Sea-Level-Function” (SL, see chapter 6.3, setting is
only possible, if an absolute pressure sensor is connected to sensor connection 1). Then enter the
altitude above sea level of the sensor’s location in meters (Alti, see chapter 6.3). When activated,
the display shows the SL-arrow and the device displays the pressure value at sea level.
When two absolute pressure sensors are connected, the sea level function for both
corresponds to the setting of sensor 1
(Only 2-channel version)
6.4.4 Averaging function
The averaging function concerns the display values (LCD and interface).
It is completely independent from the averaging of the logger function FASt and
P.dEt.
The averaging integrates the measuring values during a selectable period of time and then
calculates the average display value. It is independent from the selected kind of measuring (slow,
fast, peak detect).
As long as not enough values have been collected i. e. for the selected averaging time (seconds)
to calculate an average value, the upper display shows “----“, the lower display a ‘countdown‘.
During an active low-power-logging procedure the averring is always deactivated.
Function of min/max-value memory during averaging:
■If averaging is activated and slow measuring is selected (rAtE-Slo), the min-/max-value memory
refers to the average display value.
■If averaging is activated and fast measuring is selected (rAtE-FASt or P.dEt), the min-/max-
value memory refers to the internal measured values (fast peaks can be detected).

6.4.5 CALC: Pressure change per time dP/dt
(only for sensor 1)
The CALC function “dPdt” allows displaying pressure changes per time directly. The corresponding
measuring intervals (t.int) can be freely chosen. The device automatically saves pressure values
during this period and calculates the pressure change rate (pressure change / time) from the
current measuring value and historical data.
TARE-button: Historical data is deleted, calculation restarts.
Example: Tightness testing for sewage ducts with requirements less than -3 mbar/min in a
5 minutes test duration at a test pressure of 250 mbar.
Equipment/presetting:
■Sealing bladder and pressure pump
■Sensor: CPT6200 (measuring range 0 … 1 bar)
■bASE= Pet.n (minutes) time unit for pressure change rate
■t.int = 1:00 (1 minutes) test duration, for which the pressure change rate is calculated
■Logger: Cycl, 5 sek
Realising:
■Connect all parts, arrange all necessary sealings
■Start logger
■Charge with pressure, wait for sufficient time
■Restart calculation with button “TARE”
■Current pressure value is displayed, button “SET” changes to dP:dt display
■The display can give some preliminary information about the test result
(will it fail the test?)
■Release pressure after 5 minutes
■Stop logger
Evaluation:
Read out data logger with GSOFT, input at register “comment”:
Client, place of inspection, date, time, address / duct number, as-built data (duct type,
nominal size, etc), test instructions, pressures, tolerances, etc. as well as test result.
Therefore a comment sample can be prepared as file, company logo etc. can be added for
printing.
t.int- setting: If there are set high values the displayed values can be easily
misinterpreted, because the displayed value responds very slowly.
The displayed value is calculated: P(Tcurrent) – P(Tcurrent -t.int) / T.int
If there are no data for the whole t.int-period yet the values are extrapolated with the
already available data.
