      16.  The frequency of the trigger signal of CH2. 
      17.  It indicates the current function menu. 
18/19.     It shows the selected trigger type:   
      Rising edge triggering 
      Falling edge triggering 
  Video line synchronous triggering 
  Video field synchronous triggering 
    The reading shows the trigger level value of the corresponding channel. 
      20.  The reading shows the window time base value.   
      21.  The reading shows the setting of main time base.   
      22.  The readings show current sample rate and the record length.   
      23.  It indicates the measured type and value of the corresponding channel. “F” means frequency, “T” 
means cycle, “V” means the average value, “Vp” the peak-peak value, “Vk” the root-mean-square 
value, “Ma” the maximum amplitude value, “Mi” the minimum amplitude value, “Vt” the Voltage value 
of  the  waveform’s  flat  top  value,  “Vb”  the  Voltage  value  of  the  waveform’s  flat  base,  “Va”  the 
amplitude value, “Os” the overshoot value, “Ps” the Preshoot value, “RT” the rise time value, “FT” the 
fall time value, “PW” the +width value, “NW” the -Width value, “+D” the +Duty value, “-D” the -Duty 
value, “PD” the Delay A
B   value and “ND” the Delay A B   value. 
      24.  The  readings  indicate  the  corresponding  Voltage  Division  and  the  Zero  Point  positions  of  the 
channels. 
    The icon shows the coupling mode of the channel.   
  “—”  indicates the direct current coupling   
  “~”  indicates the AC coupling 
  “            ”  indicates GND coupling 
      25.  It is cursor measure window, showing the absolute values and the readings of the two cursors. 
      26.  The yellow pointer shows the grounding datum point (zero point position) of the waveform of the CH2 
channel. If the pointer is not displayed, it shows that this channel is not opened. 
27.  The red pointer indicates the grounding datum point (zero point position) of the waveform of the CH1 
channel. If the pointer is not displayed, it shows that the channel is not opened. 
Note: 
If a    M -symbol appears in the menu, it indicates you can turn the M knob to set the current menu. 
4. How to implement the General Inspection 
After  you  get  a  new  oscilloscope,  it  is  recommended  that  you  should  make  a  check  on  the  instrument 
according to the following steps: 
1.  Check whether there is any damage caused by transportation.   
If  it  is  found  that  the  packaging  carton  or  the  foamed  plastic  protection  cushion  has  suffered  serious 
damage, do not throw it away first till the complete device and its accessories succeed in the electrical 
and mechanical property tests.
