1. Battery electric quantity indicating symbols, including , , and .
2. Auto measurement window CH1, in which “f ”means frequency, “T” means cycle, “V” means the average
value, “Vpp” 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, „Vbase“ 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 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. Red and blue index display triggers vertical position during alternate trigger and triggers index become
green when it reaches edge trigger or video trigger.
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.
