1.2 Main Characteristics
Applying the principles of acoustic emission technology, it is simplified
operation process and easy to be operated. Multiple shortcut keys are set to
complete leak detection with one key;
Choosing AE time indicators(RMS，ASL,P) as leakage testing parameters,
thus can calibrate the valve leakage rate. Once leakage rate is calibrated, the
detector can display the referential values while testing;
Obtaining FFT frequency spectrum analysis function, can check FFT
frequency spectrum signals of current testing data at any time；
Up to 200 kinds of different valves are available, each kind of valve can store
up to 8 calibration curves；
16 digital sampling precision, sampling frequency can be adjusted based on
the frequency range of leakage signal；
6 kinds of analog filters can be selected , and can filter the noise signal
according to test condition
Two pieces of AA dry batteries to supply power, normal endurance time can
achieve 100 hours, it is easy to replace the battery, and is applicable for
long-time working outside, small volume，low weight, easy to carry；
Two kinds of alarming modes： beeping and flashing alarm, can set up two
kinds of alarm limits: first level and second level, alarming data can be saved
automatically；
Datum storage：Storage shortcuts are set up, can finish datum storage by
one button, can track and record time、date simultaneously，datum storage
volume can achieve 50,000 groups；
Communication interface： high speed of USB interface which can export
the datum, also can processes datum on the master computer.
Working way: can offer testing of valve AE parameters and valve AE leakage
rate( which are under demarcated condition)；
Daily AE valve leakage detecting can be done through operating the
functional button, easy to see and to learn, no need to operate it by entering
menu.
