OWON HDS Series Handheld DSO & DMM 6-Using the Scope
figure 4: Oscilloscope Operation Window
Description:
1. Battery electric quantity indicating symbols, including , , and .
2. Auto measurement window 1, in which “f ”means frequency, “T” means cycle, “V” means
the average value, “Vp” the peak-peak value ,“Vk” the root-mean-square value,. “MAX” the
maximum amplitude value, “MIN” 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, “AMP”
the amplitude value, “OS” the overshoot value, “PS” the Preshoot value, “RT” the rise time
value, “FT” the fall time value, “NW” the +width value, “PW” the -Width value, “+D” the
+Duty value, “-D” the -Duty value, “PD” the DelayA
B value and “ND” the
DelayA B value.
3. Auto measurement window 2.
4. The pointer indicates the horizontal triggering position.
5. This reading gives the Time Difference between the horizontal triggering position and the
screen centerline. It reads zero when the pointer is in the center of the screen.
6. The trigger state indicates the following information.
Auto: The oscilloscope is working in the automatic mode and displaying the waveform
under the non-trigger state.
Trig’d: The oscilloscope has detected a trigger and collecting the information generated
after the trigger.
Ready: All pre-triggered data have been captured and the oscilloscope has been ready to
receive trigger signals.
Scan: The oscilloscope can gather and display the waveform data continuously in scanning
mode.
Stop: The oscilloscope has stopped collecting the waveform data.
7. The green pointer shows the trigger voltage level.
8. A hidden-style menu: With the MENU key pressed, you can view or hide the menu.
9. Menu setting options: There are different setting options for different menus.
10. It reads the value of trigger voltage level.
11. The display shows the trigger signal source.
12. The reading gives the value of primary time base.
13. These graphics present the coupling modes of channel 2(CH2). The graphic “～” indicates
AC, the graphic “－” indicates DC.
14. This reading shows the vertical Voltage Unit Scale of CH2.
