Calibrate the sampling voltage by adjusting the LSB100 times voltage divisionBRT (brightness): adjust OLED brightness (25 levels)FreqPwm (PWM wave frequency): 100HZ-10KHZDuty: 1%-99%operating:All operations are completed by the EC11 encoder. Inputs include single click, double click, long press, rotation, and rotation while pressing. Main interface-parameter mode:Click encoder: run/stop samplingDouble-click the encoder: enter Wave Scroll modeRotary encoder: adjust parametersPress the rotary encoder at the same time: switch between switch optionsAutomatic and manual range switching: continuously rotate the encoder clockwise to enter the automatic range. Rotate the encoder counterclockwise to enter the manual range. Main interface-wave scroll mode:Click encoder: run/stop samplingDouble-click the encoder: enter parameter modeLong press the encoder: enter the setting interfaceRotary encoder: scroll the waveform horizontally (only available when sampling is stopped)Rotary encoder when pressed: scroll the waveform vertically (only available when sampling is stopped) Set interfaceClick encoder: N/ADouble-click the encoder: N/ALong press the encoder: return to the main interfaceRotary encoder: adjust parametersRotary encoder when pressed: switch between switch options Function: Trigger level: For repetitive signals, the trigger level can make it display stably. For single-shot signals, the trigger level can be captured.Trigger slope: The trigger slope determines whether the trigger point is on the rising or falling edge of the signal. Trigger mode:Automatic mode: continuous scanning. Click the encoder to stop or run sampling. If triggered, the waveform will be displayed on the display and the trigger position will be placed in the center of the graph. Otherwise, the waveform will scroll irregularly and display fail.Normal mode:After the pre-sampling is completed, the signal can be input. If triggered, the waveform is displayed on the display, waiting for a new trigger. If there is no new trigger, the waveform will be retained.Single mode: After pre-sampling is completed, a signal can be input. If triggered, the waveform is displayed and sampling stops. The user needs a single point encoder to start the next sample.In normal mode and single mode, confirm that the trigger level has been adjusted correctly, otherwise the waveform will not be displayed on the display.Indicator light: Usually the indicator light is on to indicate that sampling is in progress.Save settings: When exiting the setting interface, all the parameters of the setting interface and the main interface will be saved in EEPROM.
