4. Hand-painted waveform simulation
This option offers great convenience for users to simulate special
waveform or fault wave. Users only draw the shape of waveform which
needs to be simulated in central drawing area, and then configure
some parameters on the top, namely high level, low level, and cycle of
waveform, then tap
, X-431 PADII will output a waveform as desired.
Warning: Just draw a complete periodic waveform (when it is
outputted, the system will regard the waveform in the drawing area as
a periodic one). Users should draw as large as wave in drawing zone
so that the system can sample more points to reduce tolerance. While
drawing, just pay attention to the shape of waveform, high level, low
level and period can be ignored, which can be set in the Configure
option.
In Fig. 6-2, tap “Hand-painted waveform simulation”, a screen similar
to Fig. 6-8 will appear.

6.3.3 Precautions on checking vehicle sensor
Hold the connector when plugging or unplugging it. Do not pull the •
cable for unplugging.
At rst check the fuse, fusible line and terminals. Then check others •
after eliminating these faults.
When measuring voltage, the ignition switch should be on and the •
battery voltage should not be less than 11V.
When measuring voltage, please shake the lead lightly in the •
vertical and horizontal direction for more precision.
When checking whether there is open in the line, disconnect the •
CEU and the relevant sensor at rst, then measure the resistance
