8 Oscilloscope(Optional)
Oscilloscope  is  an  optional  function  of  X-431  PADII,  including 
automotive oscilloscope and automotive ignition waveform.
Automotive oscilloscope can make the auto  repair technician quickly 
judged the faults on automotive electronic equipment and wiring, and 
the oscilloscope sweep speed is far greater than the signal frequency 
of  such  vehicles,  usually  5-10  times  of  the  measured  signal. The 
automotive oscilloscope not only can quickly capture the circuit signal, 
but also can slowly display the waveform  to  observe  and analyze. It 
can  also record and store the tested  signal waveform which  can be 
played back to observe for the fast signal, having great convenience 
to  failure analysis. Either high-speed  signal  (e.g.:  Injection  nozzle, 
intermittent  fault  signal) or  the  slow-speed  signal  (e.g.  the  throttle 
position  change  and  the  oxygen  sensor  signal)  can  be  observed 
through automotive oscilloscope in an appropriate waveform.
The electronic signal can be compared and judged via measuring ve 
parameters indexes. The ve parameters indexes  are the  amplitude 
(the  maximum voltage  of  signal),  the frequency  (the  cycle  time  of 
signal),  the  shape  (the appearance of signal), the  pulse  width  (the 
duty cycle or  the time range  of signal), and  the array  (the repetition 
characteristic of signal), which can be tested, displayed, saved by the 
automotive oscilloscope. Via the waveform analysis can further detect 
the circuit fault  on  sensors,  actuators, circuits, and electronic control 
units, etc.
Refer to the Android-based Scopebox User’s Manual included with the 
Scopebox for detailed operations.
9 Borescope (Optional)
9.1 Introduction
Automotive  borescope  is  mainly applied  to  those  unseen  parts  of 
engine, fuel tank, braking system.
While testing  a  vehicle  system,  engine  is one  of  the  main  parts  to 
be checked. To  check if the internal of  a engine is qualied or not  or 
whether internal carbon deposit and  damage exists in the  engine  or 
not, we can make full use of a borescope to solve these quesitons.
X-431 PADII provides an optional function of borescope.
The borescope is  mainly composed of an inspection camera, exible 
tube and USB cable. The water-resistant camera lens with adjustable 
LED lights  enables you to observe the parts that can  not  be  seen in 
wet, dark, uid soaked places. The included exible tube is convenient 
for easy inspection and allows for access to hard-to-reach areas.
In addition, the captured pictures and videos also provide you intuitive 
data for easy analysis.
