5. The T pointer indicates the horizontal position for the trigger.
6. The pointer indicates the trigger position in the record length.
7. It shows present triggering value and displays the site of present window in
internal memory.
8. It shows setting time.
9. It indicates that there is a USB disk connecting with the oscilloscope.
10. The pointer shows the trigger level position.
11. The waveform of CH1.
12. The two blue dotted lines indicate the horizontal position of cursor measurement.
13. The waveform of CH2.
14. It indicates the measured type and value of the corresponding channel. "T" means
period, "F" means frequency, "V" means the average value, "Vp" the peak-peak
value, "Vr" 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, "ND" the Delay A->B value, "TR" the Cycle RMS, "CR" the Cursor
RMS, "WP" the Screen Duty, "RP" the Phase, "+PC" the +Pulse count, "-PC"
the - Pulse count, "+E" the Rise edge count, "-E" the Fall edge count, "AR" the
Area, "CA" the Cycle area.
15. The icon shows the selected trigger type, e.g. represents triggering on the
rising edge for an Edge trigger. The reading shows the trigger level value of the
corresponding channel.
16. Channel identifier of current bottom menu.
17. The readings show the record length.
18. The frequency of the trigger signal.
19. The readings show current sample rate.
20. The readings indicate the corresponding Voltage Division and the Zero Point
positions of the channels. "BW" indicates bandwidth limit.
The icon shows the coupling mode of the channel.
"—" indicates direct current coupling
"～" indicates AC coupling
" " indicates GND coupling
21. The reading shows the setting of main time base.
22. It is cursor measure window, showing the absolute values and the readings of the
cursors.
23. The blue pointer shows the grounding datum point (zero point position) of the
waveform of the CH2 channel. If the pointer is not displayed, it means that this
channel is not opened.
24. The yellow pointer indicates the grounding datum point (zero point position) of
