Operation
Ready for measuring
The P1:p leak detectors are
ready when the “Search Mode” bar is visible on the screen or in “Measuring
Mode” the large digits of leak rate display are visible. This situation comes about only, if:
1. the SmartSensor functions within its operating limits,
2. the suction airflow is within the nominal range, and
3. as long as the continuous self tests run successfully.
At the same time, the “READY” lamp lights up on the handset. In the Search Mode, this lamp flashes when
the instrument is ready for measuring.
Saving of measurement data
The leak detectors are capable of separately saving the measurement data for several test specimens and
outputting such data through the serial interface to a printer or a computer. Saved data is also retained when
switching the instrument off. The memory capacity permits 100 measured data for a maximum of 96 different
test specimens. Saving of a measured value is only possible in the Measuring Mode, since in the Search
Mode no quantitative measurements are run. Briefly pressing the red TRIANGLE button on the handset will
save the highest measured value which has occurred. This highest value is displayed on the screen at the
bottom on the right under “PEAK:”. Each time a value is saved or after zeroing, the peak memory is erased
and will be ready to accept the next measured value.
Using the measured value memory
As to the internal processing of the peak memory, the following applies:
- Upon pressing the red TRIANGLE button, the value of the peak memory indicated on the screen is
carried over by way of a new entry to the dataset for the test specimen.
- The peak memory as indicated on the screen is simultaneously erased and ready to accept the next
measurement.
- By operating the yellow Zero button, the peak memory is also erased.
-
A dataset for a test specimen can be “open” or “closed”. Only one test specimen dataset can be open at
a time. New data is always written to the opened test specimen dataset. A closed test specimen dataset
cannot be opened again.
- An opened test specimen dataset is closed when:
-
the programme section “User Setup” is activated
- a new worker test specimen identifier is entered (simultaneously opening a new test specimen
dataset)
- the measurement data memory is erased
- a new test specimen dataset is opened manually
- or the instrument is switched off.
- A new test specimen dataset is automatically opened, when
- the TRIANGLE button is operated and when currently no test specimen dataset is open. This will
always be the case after having switched the instrument on
- a new worker or test specimen identifier is entered.
