2.2 Description
The CPH6200 hand-held pressure indicator can be used as a calibration instrument and
also for any application which requires accurate pressure measurement.
For the hand-held pressure indicator, model CPT6200 reference pressure sensors with
measuring ranges of up to 1,000 bar (14,500 psi) are available. This hand-held pressure
indicator automatically recognises the measuring range of the connected pressure
sensor and guarantees accurate pressure measurement.
In addition to pressure sensors for gauge and absolute pressure, differential pressure can
also be measured with the CPH6200-S2 and two connected model CPT6200 pressure
sensors.
Selectable pressure units here are bar, mbar, psi, Pa, kPa, MPa, mmHg or inHg. An
integrated data logger and various other functions (such as Min, Max, Hold, Tare, zero
point correction, alarm, power-off, variable measuring rate, sea level etc.) ensure that the
hand-held pressure indicator can be used for many different applications.

4.5 Pressure sensors
CAUTION!
Damage to the instrument
If third-party reference pressure sensors are used, they can damage the
hand-held pressure indicator and the reference pressure sensor.
▶
Only use model CPT6200 reference pressure sensors!
▶
Only ever use the original connection cable from WIKA for the operation of
CPT6200 reference pressure sensors.
4.5.1 Available pressure sensors
The hand-held has been designed so that all model CPT6200 pressure sensors can
be connected without the need for any readjustment. A wide range of interchangeable
sensors is therefore available, with ranges of up to 1,000 bar (14,500 psi), see chapter
10 “Specifications”.
4.5.2 Connecting/changing pressure sensors
CAUTION!
Damage to the instrument
For overpressure or gauge sensors, the pressure compensation vent hole is
found at the top of the sensor housing.
▶
This vent (with integrated diaphragm) must always remain clear!
Before switching the instrument on, connect the reference pressure sensor,
otherwise it may not be correctly identified by the instrument.

1. To connect or change the reference pressure sensor, switch off the instrument.
2. Connect the hand-held pressure indicator and the pressure sensor to each other
electrically using a separate sensor connection cable. Use the 7-pin plug contact on
the pressure sensor for this.
3. Connect the 7-pin connector to the reference pressure sensor in accordance with the
orientation guide and secure it through the connection sleeve.
Turn the connection sleeve clockwise without much force.
4. Connect the 6-pin M-DIN connector to the hand-held on CH1 or CH2 in accordance
with the orientation guide.
When connecting the sensor connection cable to the hand-held, the pressure sensor's
connector might not locate properly in the socket. In this event you should try holding the
connector by the bend protection, rather than by the connector sleeve.
▶
Connect the connector without tilting the threads.
⇒
If the connector is positioned correctly, it can be plugged in without any significant
effort.
▶
When removing the pressure sensor, do not pull on the sensor connection cable, but
only on the connector sleeve.
4.6 Serial interface
For the data transfer to a computer, only use the interface cable from WIKA. These are
suitable for connection to a USB interface (USB driver needed) or an RS-232 interface.
The USB interface cable consists of a USB connector (model A) at one end of the cable
and a 3.5 mm stereo jack connector at the other end of the cable.
The cable is approx. 2 m (6.6 ft) long.
The RS-232 interface cable consists of a 9-pin Sub-D female connector at one end of the
cable and a 3.5 mm stereo jack connector at the other end of the cable.

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 5.2 “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.
5.2 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
use, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +70 °C (-4 ... +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
Store the instrument in its original packaging in a location that fulfils the conditions
listed above. If the original packaging is not available, pack and store the instrument as
described below:
1. Wrap the instrument in an antistatic plastic film.
2. Place the instrument, along with the shock-absorbent material, in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.

WARNING!
Physical injuries and damage to property and the environment caused
by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature
and under high pressure or vacuum may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
6.1 Commissioning
Before switching the instrument on, connect the reference pressure sensor,
otherwise it may not be correctly identified by the instrument, see chapter
4.5.2 “Connecting/changing pressure sensors”.
Before switching on, connect the reference pressure sensor(s) to the intended female
connector of the hand-held and make sure that a fully charged 9 V battery or a fully
charged rechargeable 9 V battery is inserted.
The connection sockets are marked on the instrument case with 1 or 2 correspondingly
(only with CPH6200-S2). Next to these are located the serial or analogue interfaces.
6.2 Operation
On turning the instrument on, if the logger function is selected, the integrated clock‘s
time will be displayed briefly. If a zero point correction has been carried out, the display
will indicate this by showing “nuLL-Corr”.
After changing the battery the menu for setting the clock is displayed automatically
(‘CLOC’). Check the clock and adjust if necessary (see chapter 6.4.11 “Real-time clock
(CLOC)”).

6.4.1 Pressure units (unit)
Depending on the measuring range of the current pressure sensor, the pressure value
can be displayed in any one of the following units: mbar, bar, Pa, kPa, MPa, mmHg, inHg
or psi.
6.4.2 Sea-level (SL) and altitude (Alti) correction for absolute pressure sensor
With a connected absolute pressure sensor, the instrument measures absolute pressure.
This is not to be confused with the “atmospheric 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 atmospheric
pressure altitude correction.
Setting of “SL” and “Alti”
1. Press the [SET/MENU] button for 2 seconds.
⇒
The main menu “SEt” is accessed.
2. With the [TARA] button, select the “SL” parameters.
3. With the [MIN] or [MAX] buttons, activate the “SL” parameter.
4. With the [STORE/QUIT] button, confirm the entry.
5. With the [TARA] button, select the “ALti” parameters.
6. With the [MIN] or [MAX] buttons, enter the altitude.
7. With the [STORE/QUIT] button, confirm the entry.
8. Press the [SET/MENU] button.
⇒
Return to main menu.
The setting is only possible, if an absolute pressure sensor is connected to
sensor connection 1.
When the “Sea Level” function is activated, the arrow for 'SL' is indicated below in the
display. Once the altitude of the fixed location above sea level has been entered, the
instrument displays the absolute pressure at sea level.

6. Commissioning, operation
When two absolute pressure sensors are connected, the “Sea Level” function
for both pressure sensors corresponds to the setting of pressure sensor 1.
6.4.3 Measurement types (rAtE)
The instrument supports three different measurement types for various purposes. Two of
these operate with an increased measuring rate of > 1,000 measurements/s.
6.4.3.1 Standard measurement (rAtE-SLo)
The measuring rate is 4 Hz. The averaging and filter functions are active.
Application range
■
Measurement of slowly changing or static pressures, e.g. calibration, leak testing,
atmospheric pressure measurement,
■
Highest measurement accuracy, insensitive to disturbances, low current consumption.
6.4.3.2 Peak value detection (rAtE-P.dEt)
The measuring rate is > 1,000 Hz and the measuring signal is displayed unfiltered.
Field of application in combination with logger function
■
Measurement of pressure spikes or fluctuating pressures with a resolution of < 1 ms.
■
The cyclic logger function records the arithmetic mean value, the highest and the
lowest pressure during the chosen time interval.
In this setting, there is an increased current consumption and the
measurement is susceptible to interference (also electromagnetic
interference).
6.4.3.3 Fast measurement = Fast (rAtE-FASt)
The measuring rate is > 1,000 Hz and the measuring signal is displayed filtered. As a
result, it is less sensitive to interference and the short-term spikes are filtered out. Other
than that, this function is identical to “rAtE-P.dEt”.

WIKA operating instructions, model CPH6200
EN
11221780.02 04/2019 EN/DE
6. Commissioning, operation
6.4.4 Averaging
The averaging function acts on the displayed values (display and interface). It is
completely independent of the averaging within the logger function (do not confuse
them!).
The averaging integrates the measured values during a chosen time interval and then
calculates the average display value.
The function is independent of the selected measuring rate (fast/slow measurement).
So long as a sufficiently long set time (in seconds) has not yet been measured in
order to calculate the mean value, “----” is shown in the display - in the lower display, a
'countdown' is displayed.
During the low-power logger operation, the averaging function is always deactivated.
Function of Min./Max. value memory in conjunction with the averaging function:
■
If averaging is activated and slow measurement, “rAtE-SLo”, is selected, the Min./
Max. memory value relates to the average display values.
■
If averaging is activated and fast measuring function is selected “rAtE-FASt” or
“rAtE-P.dEt”, the Min./Max. memory value relates to the internal measured values
(> 1,000 Hz measuring rate).
6.4.5 Zero point correction sensor 1 (OFS.1) or sensor 2 (OFS.2)
A zero point offset can be carried out for the respective measurement:
Displayed value = measured value – offset
Default setting
'off' = 0.0, i.e. no correction is made. The zero point correction, together with the scale
correction, is mainly used for the adjustment of sensor deviations. The entry is made in
the display unit.
6.4.6 Scale correction sensor 1 (SCL.1) and sensor 2 (SCL.2)
The scale of the corresponding measurement can be influenced by this factor (factor is in
%):
Displayed value = (measured value – offset) * (1+Scal/100)
Default setting
'off' = 0.000, i.e. no correction is made. The scale correction, together with the zero point
correction, is mainly used for the adjustment of sensor deviations.

6.4.7 Power-off delay (P.oFF)
If no button is pressed and no serial communication occurs during the power-off delay,
the instrument will automatically switch itself off. The power-off delay can be set between
1 and 120 min. If “P.oFF = oFF” then the power-off function is deactivated.
6.4.8 Instrument output (Ovt)
The output can be used as a USB or RS-232 interface or as an analogue output (0 ... 1 V).
6.4.9 Analogue output scaling with dAC.0 and dAC.1 (dAC.)
WARNING!
Damage to property through incorrect measuring instruments
By using incorrect measuring instruments, this damage could occur to the
hand-held.
▶
Only connect passive voltmeters to the analogue output.
Analogue output cannot be used during logger recordings.
With dAC.0 and dAC.1 the analogue output can be easily scaled.
▶
It must be ensured that the analogue output is not loaded too heavily, otherwise the
output value can be corrupted and the current supply of the instrument increases
correspondingly.
Loads up to approx. 10 kΩ are harmless.
⇒
If the display exceeds the value set with dAC.1, then 1 V will be output.
⇒
If the display drops below the value set with dAC.0, then 0 V will be output.
⇒
In the event of an error (Err.1, Err.2, ----, etc.) an analogue signal slightly over 1 V will
be output.
Jack connector wiring
WARNING!
Damage to property through incorrect jack connector
Using an incorrect jack connector or incorrect wiring can cause damage to
the hand-held.
▶
The 3rd connection must not be used.
▶
Only stereo jack connectors are permitted.
▶
Only use the original connection cable from WIKA.

⇒
The measuring results will automatically be recorded at the interval of the set
cycle time.
The logger records up to three measuring results:
■
Measured value or mean value (depending on selected function)
■
Min. value and max. value (Sensor 1, sensor 2, difference)
To evaluate the “Func-CYCL” data, WIKA’s GSoft (V 2.3 or higher) data logger evaluation
software must be used. The software also allows easy configuration and operation of the
logger.
When the logger function “Func-Stor” or “Func-CYCL” is activated (see menu navigation
for the main menu), the hold function is not available.
Min. and Max. value are, respectively, the minimum and the maximum measured
pressure value during the last save operation. Therefore both the current pressure value
and also any pressure fluctuations can be accurately analysed.
6.5.1 Storing individual values (Func-Stor)
Each time the [STORE/QUIT] button is pressed, a measuring result will be recorded. The
data recorded can be viewed either on the display (an additional menu item “REAd-Lo66“
is displayed when accessing the configuration menu) or through the serial interface in a
PC (GSoft).
Storable data sets: 99
A data set consists of (max.):
■
Sensor 1: measured value at that data point
■
Sensor 1: min. peak, max. peak since last data point
■
