15.1 Auto Setting
Automatic settings will choose appropriate time base scale, amplitude scale and trigger parameter
according to the input signal so that the waveform will automatically display on the screen. Press the
AUTO key to enable automatic settings.
Automatic setting only applies to the following conditions:
a. Automatic setting is only suitable for simple single frequency signal. It is impossible to achieve
effective automatic setting for complex combination waves.
b. The measured signal frequency is not less than 20 Hz, and the amplitude is not less than 20 mVpp;
the duty cycle of square wave is greater than 5%.
15.2 Run/Stop
Use the RUN/STOP key on the front panel to set. When the key is pressed and the green light is on, it
indicates the RUN state, and if the red light is on after the key press, it is the STOP state.
In the running state, the oscilloscope is continuously acquiring waveform and the upper part of the screen
shows “AUTO”; in the stop state, the oscilloscope stops the acquisition and the upper part of the screen
shows “STOP”. Press the RUN/STOP key to switch the waveform sampling between the run and stop
states.
15.3 Factory Setting
Press the DEFAULT key on the front panel, the oscilloscope can quickly restore to factory setting.
UPO1000CS series digital phosphor oscilloscope factory settings are as shown in Figure 15-1.
