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).

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

2.6 Advice for calibration service
Factory calibration certificate DKD-certificate ministerial certifications:
If the measuring device shall have a calibration certificate you have to send it inclusive the sensor to the
manufacturer. Just the manufacturer can check the factory settings and correct them if necessary.

that 2 devices are set on the same COM-port, but then you have to take care, that not both devices are
connected at the same time, because this would lead to a conflict.
4.3 Is there an automatic update function that updates the installed driver to the lat-
est version?
The driver is not updated automatically.
If there is already a suitable (for the operating system) driver during the installation, this driver will be used
automatically.
If the usage of the adapter cause problems, please make sure that the latest version of the driver for the
adapter is used and install the latest version manually (see 6.5) if necessary.

Output: Cycle time: here you can decide in which intervals measuring points should be recorded. At
the same time you can select which value will be displayed (measured value, min/max peak).
Please note: at a cycle time of more or equal than 5ms all measured values will be selected automati-
cally. A direct selection is no longer possible.

more thresholds (if these are under- or overrun the condition depending on the selected case is fulfilled
or not). The thresholds` entry is carried out in the mask on the right side. You even can select which
signal shall cause the measuring start. But this is only available when the cycle time is higher or equal

At a cycle time of less than 5ms, 200 measured values are possible.
At a cycle time more or equal than 5ms 50 data sets are possible, which are made up of four different
series of measurements (50 data sets x 4 series of measurements = 200 measuring values).
Example: a cycle time of 10ms is selected. There will be 10ms long 50 data sets (=500ms) recorded
before the normal measuring will be started.
Stop: Here it is possible, in analogy to the start conditions, to set the stop conditions. Besides the man-
ual stop and the measuring stop after a certain time, the stop by specified thresholds is available, too (if
these are under- or overrun the condition depending on the selected case is fulfilled or not). The
thresholds` entry is carried out in the mask on the right side. You even can select which signal shall
cause the measuring stop. But this is only available when the cycle time is higher or equal than 5ms.
