measurement is always performed when the oscilloscope is running or stopped.
Press [MEASURE] on the front panel to enter the measurement interface, and press F3 to select the
DVM to enter DVM setting interface.
Press CH1 Enable, CH2 Enable to enable any channel or all channels of DVM.
Press CH1 Type, CH2 Type to select the data type displayed by DVM.
DC RMS: displays the root-mean-squre value of the acquired data.
AC RMS: displays the root-mean-squre value of the acquired data with the DC component removed.
DC: Display the DC value of the acquired data.
The display in the middle of the DVM box is the corresponding ratio of the current measured voltage
value to the range corresponding to the eight vertical grids on the screen with the selected volt/div
(turn the volt/div knob).
2.12. Acquire
2.12.1. Run Control
Press the [Run/Stop] or [Single] button on the front panel to run or stop the sampling system of the
scope.
When the [Run/Stop] is green, the oscilloscope is running, that is, acquiring data when trigger
conditions are met. To stop acquiring data, press the [Run/Stop] button. When stopped, the last
acquired waveform is displayed.
When the [Run/Stop] button is red, data acquisition is stopped. Red "Stop" is displayed next to the
trademark logo in the status line at the top of the display. To start acquiring data, press [Run/Stop].
To capture and display a single acquisition (whether the oscilloscope is running or stopped), press
[Single] button. The Single run control lets you view single-shot events without subsequent waveform
data overwriting the d isplay.
When [Single] is pressed, the display is cleared, the trigger mode is temporarily set to Normal (to keep
the oscilloscope from auto-triggering immediately), the trigger circuitry is armed, the Single key is
illuminated, and the oscilloscope waits until a user defined trigger condition occurs before it displays a
waveform.
When the oscilloscope triggers, the single acquisition is displayed and the oscilloscope is stopped (the
[Run/Stop] button is illuminated in red). Press [Single] button again to acquire another waveform.
