Displaying The Measurements; Stop Recording - WIKA CPT2500 Instruction Manual

Pressure sensor CPT2500 with USB adapter CPA2500 and USBsoft
To start a new recording please select "start new recording" or click at the corresponding toolbar
symbol.
Now you can choose from an assortment of start and stop conditions and define the output data.
Choice of the recording mode:
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.
Start: You have to select the desired condition under the different possibilities. If „immediately" is se-
lected the measuring will start directly after starting it. At the other conditions you have to define one or
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
than 5ms. You can make this entry on the left side under „Start Signal".
The preTrigger makes it possible for you to detect values before the normal values measured (after the
start condition).
After the completion measurement the additional measured values will be shown in the register „Data",
too.
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.
You can make this entry on the left side under „Stop Signal".
The Stop Delay effects a continuous measurement until the defined time is up. After this the measuring
will be stopped automatically.

5.3.4 Displaying the Measurements

To read the measuring values the cyclic recording has to be stopped first.
After loading the data, the values will be shown in the register „Data" automatically.
The white fields for the table heading can be edited.
In the register „Comment" you can write arbitrary texts.
If you want to view the data later again, you have to save them now by choosing „Save" or „Save as" in
the menu „File".

5.3.5 Stop Recording

If a recording is stopped, data are preserved which have been received until that moment.
