Parameter:

Input voltage: DC 3.7-5V
Appearance size: 57*35mm
Weight: 25g

Specification:

MCU: STC8AK64S4A12 27MHz
Controller: an EC11 encoder
Input: single channel
Sec/div: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us (100us is only available in auto trigger mode)
Voltage range: 0-30V

Main interface parameters:
Frequency: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us (100us is only available in auto trigger mode)
Voltage range: 0-30V
Trigger level: trigger voltage level
Trigger slope: rising edge, falling edge trigger
Trigger mode: A-automatic mode, N-normal mode, S-single mode
Main interface status:
run: sampling run
stop: sampling stop
fail: In the automatic trigger mode, the trigger level of the waveform is exceeded
Auto: Uterine voltage range

Parameter setting interface:
PMode (drawing mode): display the waveform with vector active points
LSB: sampling coefficient. Calibrate the sampling voltage by adjusting the LSB
100 times voltage division
BRT (brightness): adjust OLED brightness (25 levels)
FreqPwm (PWM wave frequency): 100HZ-10KHZ
Duty: 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 sampling
Double-click the encoder: enter Wave Scroll mode
Rotary encoder: adjust parameters
Press the rotary encoder at the same time: switch between switch options
Automatic 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 sampling
Double-click the encoder: enter parameter mode
Long press the encoder: enter the setting interface
Rotary 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 interface
Click encoder: N/A
Double-click the encoder: N/A
Long press the encoder: return to the main interface
Rotary encoder: adjust parameters
Rotary 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.
