1.1 General safety instructions
This device has been designed and tested in accordance with the relevant safety regulations for electronic devices. However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety advise given in this manual is followed when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed so long as the device is not subjected to any climatic conditions other than those stated under “8. Specification“.
2. The device and sensors must be handled with care (don‘t throw, hit, etc.). Protect plugs and sockets from contamination.
3. If the device is moved from a cold to a warm environment, condensa tion may cause the equipment to fail. You should therefore ensure the device temperature has adjusted to the ambient temperature before trying to switch it on.
4. If the instrument is to be connected to other devices (e.g. via serial interface) care must be taken when designing the equipment connec­tions. It is possible that internal wiring within the external device (e.g. connection of GND to Earth) may cause excessive voltages which could harm or destroy the instrument or other connected devices.
If the device is operated with a faulty mains power supply (e.g. short circuit from mains voltage to output voltage) this could result in dangerous voltages at the device (e.g. at the sensor socket or serial interface).
5. If there is any risk whatsoever involved in using it, the device must be switched off immediately and marked accordingly to prevent re-use.

1.2 Operation and maintenance advice
Battery operation
If ´bAt´ is shown in the lower display the battery is low and needs to be replaced or recharged (using the appropriate battery charger as shown in the current CPH6200 price list ). The device will, however, work normally for a limited period. If ´bAt´ is shown in the upper display the voltage is too low to operate the device; the battery will be completely flat.
A) If the device is not going to be used for some time, we advise that
the battery is removed.
B) The real time clock has to be set again after reconnect to the battery
Mains operation with power supply
When using a power supply please note that the operating voltage must be 10.5 to 12 V DC. Do not use with higher voltages! Cheap 12 V-power supplies often have excessive no-load voltage, and we therefore recommend using regulated-voltage power supplies. Trouble-free operation can be ensured by using our own power supply unit (see current CPH6200 price list). Before connecting the power supply to the mains make sure that its operating voltage matches the local mains voltage.
Connecting/Changing sensors
Only use sensors model CPT6200. Using other sensors can damage the instrument! Switch off device before changing the sensor and connect the sensor before turning the device back on, otherwise the sensor may not be identified correctly.
The CPH6200 and the pressure transmitter are connected using a discrete connecting cable. When changing the pressure transmitter, always connect and disconnect at the transmitter end of the cable. To connect the transmitter, rotate the plug till it locates in the guide slot, allowing it to plug in. Then tighten the safety collar (by screwing it lightly in a clockwise direction).
When connecting the cable to the CPH6200, the connector might not locate properly in the socket. In this instance you should try holding the plug by the cable strain relief, rather than by the connector housing. If the plug is correctly located, it will slide in smoothly. To disconnect the sensor hold it by the plug to release the connector lock. Do not pull the cable to release it.
For gauge sensors, the pressure compensation vent hole is found at the top of the sensor housing. This vent (with integral membrane seal) must be kept clear without fail.
Maintenance advice
Both the CPH6200 and sensors are manufactured using solidstate technology, and contain no moving parts which could wear. If the instrument housing has been opened, the warranty becomes invalid.
If cleaning is necessary, use a cloth wetted with mild detergent. Avoid any solvents, caustic or abrasive substances.
As is normal for all measuring instruments, the accuracy of the device should be tested at regular intervals (approx. once per year - see Section 7).
1.3 Electrical connections
On the upper edge of the device:
The connector sockets for attaching the CPH series pressure sensors, CH1 and CH2 (CH2 only with the 2-channel version), are located on the top edge of the CPH6200 (see Section 5), as is the socket for the WIKA interface cable (see Section 4).
Connection for WIKA interface cable or optional analogue output
GB
CH1 CH2 (only for 2-channel version: CPH6200-S2)
Operation as analogue output: connection via suitable cable.
The output mode has to be configured via menu and influences battery life!
On the left side of the device:
The mains adapter socket for connecting the power supply unit (see current CPH6200 price list) is located on the left side of the handheld unit.

** This menu can oly be invoked if a refering sensor is connected to
connection 1. When using a second sensor at connection 2 then changes are taken over.
2. Configuration
To change device settings, press the ´Set/Menu´ key for 2 seconds. This will access the configuration menu (main display: “SEt“). Pressing the ´Set/Menu´ key again scrolls down the menus, pressing the ´Tare´ key scrolls across to the associated parameters, which can then be selected with the ´Tare´ key. The parameters can be altered using the ´Min´ or ´Max´ keys. Pressing the ´Set/Menu´ key again saves the settings and returns you to the main configuration menu. The ´Store/Quit´ key exits the configuration and returns you to standard measuring mode.
2.1 (Unit) Choice of pressure units
Depending on the pressure range, the pressure value can be displayed in any one of the following units: mbar, bar, Pa, kPa, MPa, mmHg, inHg or psi.
2.2 (SL) Sea-level correction for absolute pressure sensors
If an absolute pressure sensor is connected to the instrument, then the device displays the true absolute pressure measured by the sensor. This does not necessarily equate to the values given by weather stations, which give the pressure at sea-level. Usually the sensor is situated above sea-level and therefore, if the value at sea-level (zero) is to be measured, the pressure loss resulting from the elevation above sea­level must be considered! To correct the displayed value activate the “Sea-Level-Function“ (SL). (Setting is only possible, if the abs. Pressure sensor is connected to sensor socket 1.) Then enter the sensor‘s height above sea-level in metres (Alti). When activated, the display shows the SL-arrow and the device displays the absolute pressure value relative to sea-level.
When two absolute pressure sensors are connected, the sea level function for both is corresponding to the setting of sensor 1.
2.3 (rAtE) Choice of measuring rates: “rAtE-Slo, -P.dEt, -FASt“
GB
Three options of measuring rate are supported. Two of them work with high measuring frequencies of over 1000 measurements per second. Whichever one of them was selected during configuration (see above), this will be displayed in the lower display: “P.dEt“ or “FASt“.
2.3.1 rAtE-Slo: standard measuring
Measuring rate 4 Hz, averaging and filter functions are active. Application: Measurement of slowly changing or static pressures, e.g. leak testing, atmospheric pressure... Highest accuracy, high noise immunity (EMI and unstable measuring signals), low power consumption.
11221780.1.3 01/2009 GB/D/F/E
WIKA Operating Instructions Hand-Held Pressure Indicator 13
GB
11221780.1.3 01/2009 GB/D/F/E
WIKA Operating Instructions Hand-Held Pressure Indicator14
2.3.2 rAtE-P.dEt: peak detection
Measuring rate > 1000 Hz, the value is displayed unfiltered. Application with logger function: Measuring of pressure spikes or fluctu­ating pressures with a resolution of < 1.5 ms. The cyclic logger function records the arithmetic mean value, the highest and the lowest peak during the chosen time interval.
Higher power consumption, measuring is sensitive to noise (EMI,..).
2.3.3 rAtE-FASt: fast filtered measuring
Measuring rate > 1000 Hz, but the value is filtered slightly (higher noise immunity than P.dEt, small peaks will be filtered out), apart from that, identical behaviour to P.dEt.
2.4 Averaging function
The averaging function acts on the displayed values (LCD and serial interface). It is completely independent of the averaging within the logger function, please don‘t mix them up! The averaging integrates the measured values during a chosen time interval and then calculates the average display value. It is independent of the selected measuring rate (slow, fast, peak detect). Until sufficient values to calculate an average value have been collected (dependant on selected averaging time), the upper display shows “----“, the lower display shows a ´countdown´. During an active low-power-logging procedure the average is always deactivated.
Operation of min/max-value memory in conjunction with the averaging function:
If averaging is activated and 'slow' measuring rate is selected (rAtE-
Slo), the min-/max-memory value relates to the average display value. If averaging is activated and 'fast' measuring rate is selected (rAtE-
FASt or P.dEt), the min-/max-memory value relates to the internal measured values (pressure spikes can be detected).
2.5 Zero correction sensor 1 (OFS.1) and sensor 2 (OFS.2)
A zero displacement can be carried out for the measured value:
value displayed = value measured - offset
Standard setting: ‘off‘ = 0.0°, i.e. no zero displacement will be carried out. Together with the scale correction (see below) this factor is mainly used to compensate for sensor deviations. Input is in the display unit.
2.6 Span correction sensor 1 (SCL.1) and sensor 2 (SCL.2)
The scale of the measuring can be influenced by this setting (factor is in %):
displayed value = measured value * (1+Scal/100)
Standard setting: ‘off‘ =0.000, i.e. value is not corrected. Together with the zero displacement (see above) this factor is mainly used to compen­sate for sensor deviations.
2.7 (P.oFF) Power off function
If no key is pressed, and no serial communication occurs during the interval set in configuration (P.off), the device will automatically switch itself off to save battery power. If P.oFF = oFF then the automatic power off is deactivated.
GB
2.8 (Out) Output
The output can be used as interface (RS-232 or USB) or as analogue output (0 ... 1 V).
2.8.1 (Adr.) Serial communications address
This parameter has been included in preparation for future operation with multi-point monitoring systems.

WIKA Operating Instructions Hand-Held Pressure Indicator 15
GB
11221780.1.3 01/2009 GB/D/F/E
WIKA Operating Instructions Hand-Held Pressure Indicator16
2.8.2 (dAC.) Analogue output – scaling with (dAC.0) and (dAC.1)
Analogue output can not be used during logger recordings
With the dAC.0 and dAC.1 values the output can be rapidly scaled to your efforts. Keep in mind not to connect low-resistive loads to the output, other­wise the output value will be wrong and battery life is decreased. Loads above ca 10 kΩ are uncritical. If the display exceeds the value set by dAC.1, then the device will apply 1 V to the output. If the display falls below the value set by dAC.0, then the device will apply 0 V to the output. In case of an error (Err.1, Err.2, no sensor, etc.) the device will apply slightly above 1 V to the output.
Plug wiring:
The 3rd contact has to be left floating! Only stereo plugs are allowed!
2.9 (AL.) Alarm
There are three possible settings: Alarm off (AL.oFF), on with audio alarm (AL.on), on without audio alarm (AL.no.So). The following conditions will prompt an alarm to be displayed, if the alarm function is activated (on or no.So):
Value is below lower alarm limit (AL.Lo) or above upper alarm limit
(AL.Hi). Sensor error (Sens-Erro)
Low battery (bAt)
Fe 7: System error (always with sound)
When an alarm occurs, the alarm arrow flashes, and, during serial communication, the 'PRIO'-flag is set within the transmitted message.
If the horn sound of one channel will be switched on/off (on or no.So), then this horn sound setting will automatically be copied to the other activated channels.
2.10 (CLOC) Real time clock
The real time clock is needed for time-stamping each data point record­ed within the logger function. As a result, the clock settings should be checked regularly. If the battery has been replaced the appropriate menu 'CLOC' will be accessed automatically.
3. Operation of logger
The device supports two different logger functions:
“Func-Stor“: each time the ´Store/Quit´ key is pressed a data point
will be recorded.
“Func-CYCL“: measurements will automatically be recorded at a
defined interval, set within the logger menu ‘CYCL‘ until the logger is stopped or the logger memory becomes full. Logging is started by pressing the ´Store/Quit´ key for 2 seconds.
The logger records up to 3 measurement values for each interval:
Current or mean value (depending on logger setting, see below), Min-
Peak and Max-Peak. (Sensor 1, Sensor 2, difference)
To evaluate the data, WIKA's Data logger evaluation software GSOFT (V
2.3 or higher) must be used. The software also allows easy configuration
and operation of the logger.
GB
If the logger is selected (Func-STOR or Func-CYCL) the hold function is deactivated; the ´Store/Quit´ key is then used solely for the operation of the logger functions.
Min- and Max-Peak are, respectively, the minimum and the maximum measured values during the last measurement interval. Therefore both the instantaneous pressure values and the measured fluctuations can be better analysed.
3.1 “Func-Stor“: Storing discrete measurements
In this mode, each time the ´Store/Quit´ key is pressed a measure­ment and its time stamp will be recorded. The data recorded can be viewed either on the display (an additional menu item “REAd-LoGG“ is displayed when scrolling through the Configuration menu) or through the
11221780.1.3 01/2009 GB/D/F/E

serial interface and a PC running the GSOFT-software.
GB
11221780.1.3 01/2009 GB/D/F/E
WIKA Operating Instructions Hand-Held Pressure Indicator18
Max. number of measurements: 99
The data recorded includes the following values:
Sensor 1 instantaneous value at that data point
Sensor 1 Min-Peak, Max-Peak since last data point
Sensor 2* instantaneous value at that data point
Sensor 2* Min-Peak, Max-Peak since last data point
Instantaneous difference (Sensor 1 - Sensor 2)* at that data point
Min-Peak, Max-Peak of the difference (Sensor 1 - Sensor 2)*, Min-
Peak, Max-Peak since last data point Time and date stamp of that data point
* Only for 2-channel version CPH6200-S2
After each recording “St. XX“ will be displayed for a short time. XX represents the number of the data point.
If the logger memory already contains data: When the ´Store/Quit´ key is pressed for 2 seconds, the option to clear the logger memory will be displayed:
clear clear nothing all data points (cancel menu)
clear the last data point
Use the ´Min´ or the ´Max´ key to display the required option. The ´Store/Quit´ key selects that choice.
If the logger memory is full, the display will show:
Viewing Recorded Measurements
Within the “LoGG-Stor“ function the measurements can be viewed directly on the instrument display as well as through a computer (“Func­CYCL“ only allows for the data to be viewed on computer). Press the ´Set/Menu´ key for 2 seconds: The first menu displayed is now “rEAd­LoGG“ (read logger data). By then pressing the ´Tare´ key, the last measurement recorded will be displayed; pressing the ´Tare´ key again scrolls between the different values related to this data point. Pressing the ´Min´ key or ´Max´ key selects different data points.
3.2 Func-CYCL“: Automatic datalogging with adjustable cycle-time
The Logger cycle-time is adjustable (see Configuration). For example, setting “CYCL“ = 60: A measurement is made every 60 seconds.
When the slow measurement “rAtE-Slo“ is chosen, additionally a low power function is available: “Lo.Po“. If “Lo.Po“ is on, the device only will take a measurement at the point of time of the recording. In between the recordings the measuring shut‘s down. This decreases the power consumption enormously and there­fore is recommended e.g. for long time recordings where no mains adapter is available.
Max. number of measurements: CPH6200-S1: 10000 CPH6200-S2: 4000 (at max. 64 recording sequences) Cycle-time: 1 ... 3600 seconds (=1 h), selectable
from the configuration menu
A measurement contains:
Slow measuring rate (rAtE-SLo):
- Sensor 1 current value at that data point
- Sensor 1 Min-Peak, Max-Peak since last data point
- Sensor 2* instantaneous value at that data point
- Sensor 2* Min-Peak, Max-Peak since last data point
- Instantaneous difference (Sensor 1 - Sensor 2)* at that data point
- Min-Peak, Max-Peak of difference (Sensor 1 - Sensor 2)*, Min­Peak, Max-Peak since last data point
GB
Fast measuring rate (rAtE-FASt, -P.dEt):
- Sensor 1 average since last data point
- Sensor 1 Min-Peak, Max-Peak since last data point
- Sensor 2* average since last data point
- Sensor 2* Min-Peak, Max-Peak since last data point
- Average difference (Sensor 1 - Sensor 2)* since last data point
- Min-Peak, Max-Peak of difference (Sensor 1 - Sensor 2)*, Min-Peak, Max-Peak since last data point
* Only for 2-channel version CPH6200-S2

4. The serial interface
For data transfer to a computer there are two electrically-isolated inter­face adapters available for the connection of the CPH6200 to a RS-232 or USB interface (USB-driver necessary). WIKA‘s Data logger evaluation software GSOFT (see current CPH6200 price list) is used to display the data. To avoid transmission errors, there are several security features implemented (e.g. CRC).
5. Available pressure sensors
The instrument has been designed so that all sensors model CPT6200 can be connected without the need for any configuration or recali­bration. There is therefore a wide range of interchangeable sensors
11221780.1.3 01/2009 GB/D/F/E

1.2 Betriebs- und Wartungshinweise
Batteriebetrieb
Wird in der unteren Anzeige "bAt" angezeigt, so ist die Batterie verbraucht und muss erneuert werden bzw. der Akku ist leer und muss mit dem dafür vorgesehen Akkuladegerät (siehe aktuelle Preisli­ste CPH6200) geladen werden. Jedoch ist noch für eine gewisse Zeit die Gerätefunktion gewährleistet. Wird in der oberen Anzeige "bAt" angezeigt, so ist die Batterie ganz verbraucht. Batterie und Akku sind nur sachgemäß zu benutzen und ordnungsgemäß den aktuellen, nationalen Vorschriften zu entsorgen. Bei Lagerung des Gerätes über 50 °C muss die Batterie entnommen werden.
Wird das Gerät längere Zeit nicht benutzt, sollte die Batterie / der Akku herausgenommen werden. Die Uhrzeit muss nachher jedoch wieder neu eingestellt werden.
Netzgerätebetrieb
Beim Anschluss eines Netzgerätes muss dessen Spannung zwischen 10,5 und 12 V DC liegen. Keine Überspannungen anlegen! Einfache Netzgeräte können eine zu hohe Leerlaufspannung haben, dies kann zu einer Fehlfunktion bzw. Zerstörung des Gerätes führen! Wir empfehlen daher unser Netzgerät (siehe aktuelle Preisli­ste CPH6200) zu verwenden. Vor dem Verbinden des Netzgerätes mit dem Stromversor-gungs­netz ist sicherzustellen, dass die am Netzgerät angegebene Betriebsspannung mit der Netzspannung übereinstimmt.
Sensoren anstecken/wechseln
Nur Sensoren des Types CPT6200 verwenden! Mit anderen Sensoren kann es zur Zerstörung des Messgerätes und des Sensors kommen. Zum Sensorwechsel Gerät ausschalten. Sensor vor dem Einschalten des Gerätes anstecken, sonst wird er vom Gerät evtl. nicht richtig erkannt.
Digitalgerät und Sensor werden mittels eines separaten Verbindungs­kabels elektrisch miteinander verbunden. Für den Sensorwechsel sollte bevorzugt der 7-polige Steckkontakt am Sensor benutzt werden. Zum Anschluss eines Sensors stecken Sie die 7-polige Steckverbindung am Sensor gemäß der Orientierungsführung zusammen und sichern Sie diese durch die Überwurfhülse (Überwurfhülse ohne größeren Kraftauf­wand in Uhrzeigersinn drehen). Beim Anstecken des Kabels am Digitalgerät kann es vorkommen, dass der Stecker nicht richtig in die Buchse einrastet. In diesem Fall den Stecker beim Anstecken nicht an Steckerhülse sondern am Knickschutz halten. Stecker nicht verkantet anstecken. Bei richtig angesetztem
