1 General
The CPA2500-adaptor makes it possible to connect a pressure sensor model CPT2500 directly to the
USB-port of a personal computer. The associated Software USBsoft2500 allows to conduct the moni-
toring settings and to display the measuring data automatically in the adjusted cycle time. This mode is
especially adapted for the analysis of pressure curves and the survey of pressure peaks (with pre-
trigger).

1.3 Safety regulations
This device was designed and tested considering the safety regulations for electronic measuring devic-
es. Faultless operation and reliability in operation of the measuring device can only be assured if the
General Safety Measures and the devices specific safety regulation mentioned in this operating instruc-
tion are considered.
1. Warning: Open pressure connections only after the system is without pressure!
2. Warning: Please make sure that the pressure sensor is only used within the overpressure safety
limit!
3. EMC advice: Do not connect a cable that exceeds a length of 3 m.
4. Safety advice: Have repairs performed by the manufacturer only.
5. Faultless operation and reliability in operation of the measuring device can only be assured if the

6. By faulty handling of the interface adapter a damage of the device cannot be excluded. Likewise a
damage of your attached device is possible. In such case we cannot assume any warranty.
The manufacturer will not assume any warranty for damages to other devices resulting by use of the
interface adapter.
7. Standard regulations for operation and safety for electrical, light and heavy current equipment have
to be observed, with particular attention paid to the national safety regulations (e.g. VDE 0100).
8. When connecting the device to other devices (e.g. the PC) the interconnection has to be designed
most thoroughly, as internal connections in third-party devices (e.g. connection of ground with pro-
tective earth) may lead to undesired voltage potentials.
9. The device must be switched off and must be marked against using again, in case of obvious mal-
functions of the device which are e.g.:
- visible damage
- no prescribed working of the device
- storing the device under inappropriate conditions for longer time
When not sure, the device should be sent to the manufacturer for repairing or servicing.
10. Warning: Do NOT use this product as safety or emergency stopping device or in any other applica-
tions, where failure of the product could result in personal injury or material damage.
Failure to comply with these instructions could result in serious injury and material dam-
age

2 General handling instructions
2.1 Operation mode
The measurement is started by a trigger condition. Then the device automatically gives back the meas-
ured values in the adjusted cycle time without any request, until the stop condition is fulfilled. For the
communication and configuration of the device, the software USBSoft2500 is necessary.
Adjustable parameters are among other ones:
Cycle time: 1ms ... 10sec., programmable in steps of ms
Measured values:
cycle time < 5 ms it is possible to choose the values to be recorded
(measurand, min. peak, max. peak)
cycle time > 5 ms a complete data set is always recorded, containing the following values:
- actual pressure at the moment of the data transfer
- minimum pressure (min. peak) in the period of the last cycle time
- maximum pressure (max. peak) in the period of the last cycle time
- average value of the pressure in the period of the last cycle time
Trigger conditions: 5 for the measuring start / 6 for the measuring stop
Pre-trigger: 50 data sets (at a cycle time of 5ms) respectively 200 measurands (cycle
time < 5 ms)
2.2 To connect / change sensors
Only pressure sensor model CPT2500 are allowed to be used! If other sensors are used the adapter and
the sensor may be destroyed.
To change the sensor you have to disconnect the adapter. Sensors have to be connected before acti-
vating the adapter. Otherwise they are not found by the adapter correctly.
During the connecting it is possible that the connector does not snap in the jack correctly. In this case you
have to hold the connector at the bend relief not at the casing. Don`t plug the connector wedged. An accu-
rate attached jack can be easily plugged in without great effort. To disconnect the sensors it is not allowed
to pull at the cable. In this case you have to hold the connector at its casing.
2.3 Zero correction of the pressure sensor ('OFFS')
For the measurement a zero offset can be conducted:
shown vale = measured value - offset
The zero correction in combination with the slope correction (see below) is mainly used to adjust the devi-
ation of sensors. The entry has to be made in the configuration software. The offset information will be
stored in the sensor. So you can set it individually for each sensor.
2.4 Slope correction of the pressure sensor ('SCAL')
The measurement`s slope can be affected by this factor (factor in %):
shown value = measured value * (1 + scale / 100)
The slope correction in combination with the zero correction (see above), are mainly used to adjust the
deviation of sensors. The entry has to be made in the configuration software. The scale information will be
stored in the sensor. So you can set it individually for each sensor.
2.5 Pressure connection to the pressure sensor
The measuring adapter is conceived that way, that all sensors of the CPT2500-series can be connected
without new calibration. Therefore a multiplicity of fully exchangeable sensors for metering ranges of
-1 ... 0 bar relative to 0 ... 1000 bar absolute are available.
For overpressure, low-pressure or absolute pressure measurements: screw the sensor in the threat
