Device Connections and Controls

External Connections:

Test Signal output: For testing purposes.
BNC Connector (Signal Input): For connecting probes.
Power Supply Connectors: 5.5 x 2.1mm jack for 9V DC power input.

Power Switch: Located on the device to turn it on/off.

Basic Button Functions:

Button	Press	Hold down
V/DIV	Switch to horizontal baseline, vertical component setting	Long press in the setting (except for vertical component) to enter manual calibration mode.
SEC	Switch time base, PWM output setting	Save the setting parameters.
TRIGGER	Switch Trigger mode, trigger position setting	Show/close detailed parameters.
OK	Stop/Run	Show/close detailed parameters.
ADJ	Switch fast/slow movement-Switch settings in PWM mode	Show/close detailed parameters.

Attention and Operations

Attention:

Power supply voltage must not exceed 10 V, otherwise it might damage the ICs inside.
Allowed maximum signal input voltage is ±50 Vpk with any probe (including the supplied clip probe).

Power Supply: Connect a regulated 9 Vdc power supply to the 5.5 × 2.1 mm jack at the bottom (centre positive). Battery operation is also possible. Ensure the 9V battery buckle is installed correctly.

Probe: Connect the probe to the BNC connector at the top. The red clip is the active signal; black is 'ground' (GND). When using a double-insulated plugpack, do not connect the GND clip to any voltage more than 50 V above mains 'ground' potential to avoid exceeding insulation ratings.

Trigger Modes

AUTO: Triggers are generated internally to provide continuous display updates regardless of signal changes.
NORM: The display updates each time the specified trigger condition (polarity and level) is met.
SING: A single capture/display occurs when the specified trigger condition (polarity and level) is met. Press the [OK] button to arm another single capture.

About Trigger States

The oscilloscope supports Auto, Normal, and Single trigger modes for capturing waveforms. When the timebase is set to 50 ms/div or slower and the trigger mode is AUTO, the scope switches to Rolling Mode, where the waveform scrolls continuously from right to left. Triggering is disabled in Rolling Mode.

Calibration Instructions:

Pull out the voltage probe.
Enter calibration mode by long-pressing the V/DIV key.
Adjust the voltage gear from 5mV to 20V (order does not matter).
Switch the coupling mode and repeat step 3 for all three coupling modes until calibrated.
Exit calibration mode. Parameters are saved upon exit. Shutting down without exiting will invalidate the calibration.

Firmware Upgrade Instructions

Use the CH340 serial tool to connect to the RX, TX, and GND pins on the board.
Press and hold the OK button while turning on the device to enter firmware upgrade mode.
Open the host computer software, connect to the corresponding port, and set the baud rate to 115200.
Select the firmware file.
Start the download, wait for completion, and restart the device.

Troubleshooting

Problems	Possible Causes
No display (black)	Check that your power supply's DC plug is centre-positive, and the voltage is between 8 and 10 Vdc.
Bad V+	(1) Connector 37 defective. (2) Diode D2 open or damaged.
Bad V-	(1) Bad C12 and/or C13. (2) U5 (7660) bad soldering or defective. Hint: Check with R27 disconnected to determine if the issue is caused by load or source.
Bad AV-	(1) R27 bad soldering or wrong value. (2) Shorts between AV- and ground.
Bad AV+	(1) R26 bad soldering or wrong value. (2) Shorts between AV+ and ground.
V1 does not close to 0 V	(1) SWI not set to GND position. (2) Bad soldering on R1 and/or R2. (3) Bad soldering on U1.
V2 does not close to 0 V	(1) SWI not set to GND position. (2) Bad soldering on R3 and/or R4. (3) Bad soldering on U1.
V3 does not close to 0 V	(1) Bad soldering on U1 and/or U2. (2) Bad soldering on R5 and/or R6.
Bad V4	(1) Incorrect V4. If V4 is correct, perform factory default restore as described in (2).
No Trace	(1) Make sure trigger mode is AUTO and timebase is 1ms. (2) Hold down [SEC/DIV] and [TRIGGER] buttons simultaneously for 3 seconds.
Rotating ADJ rotary-encoder does nothing	Check for shorts (or open-circuit/'dry' solder joints) between pins 1 and 3 of the encoder, pins 1 and 2 of the J2 connector, or an open/dry' solder joint at pin 2 of the encoder.

Self-check for Product Failure

Has been shock or drop during use.
No good recovery installation after disassembling the product casing.
Product power supply issues:
- Using an overvoltage adapter (supply voltage must not exceed 10 V, otherwise ICs may be damaged).
- 9V battery buckle or power adapter is damaged.
- Forcibly cutting off power before shutting down; ensure the product switch is turned off first, then cut the power.

Q&A

Q1: Why need to trigger?

A1: When the oscilloscope is not triggered, the signal (automatic mode) will be randomly grabbed and generate an image. Since the signal is continuous, the waveform is not regular. After triggering, you can get regular waveforms to analyze research.

Q2: How many trigger modes have this oscilloscope?

A2: This oscilloscope has 3 trigger modes: Auto, Normal, and Single, allowing you to easily capture the current waveform.

Q3: Trigger level not center trigger level

A3: Hold down the [TRIGGER] button for about 3 seconds. This will set the trigger level to the medium value of signal amplitude.

Q4: Display white screen.

A4: Ensure the power supply voltage is in the range of 8-10V. Confirm the signal input is within the equipment parameters. Consider performing a Default Restore.

Q5: Why does the encoder knob rotate trigger level up and down without change?

A5: The encoder knob requires fine-tuning. Adjust it slowly for proper operation. Fast adjustments may be considered invalid.

Q6: Why my voltage numbers are incorrect?

A6: There are two possible causes for incorrect voltage display:

The reference point has not been calibrated. Perform VPos alignment as instructed in the manual (it is strongly suggested to do a factory default restore before VPos alignment to ensure all parameters are valid).
The gain of the analog channel is incorrect. Perform VPos alignment as instructed in the manual (it is strongly suggested to do a factory default restore before VPos alignment to ensure all parameters are valid).
