Operation Instructions
Multimeter operation:
Oscilloscope operation:
- Automatic settings:
When the measurement waveform is uncertain or the manual setting is avoided short press AUTO, and the oscilloscope will automatically adjust the time base parameters, starting voltage, etc. to obtain an accurate and suitable waveform for observation. - Voltage/Time Base Adjustment:
Press the FUNC key to select the VOL/TIME base adjustment function, press the direction keys to set the voltage scale value up and down, and press the direction keys to set the time scale value left and right. - Move:
Press the FUNC key, select the move function, and press the direction keys to adjust the waveform position up or down relative to the center of the screen; Pressing the direction keys to adjust the waveform position left or right is equivalent to moving the center of the screen to the left or right. - Trigger:
- Cursor setting: Press the FUNC key to select the trigger function, press the direction keys to move up and down to trigger the cursor position, and the screen T value (trigger voltage) also changes accordingly.
- Trigger method: Press the MENU key to pop up the setting window, and then press the direction key to select the trigger method option left and right. The up and down direction keys are used to select different trigger methods, including automatic, normal, and single.
- Automatic: Real-time collection and refresh of waveforms without retaining them.
- Normal: When the amplitude of the collected signal reaches the set triggering level, the triggering system will lock the waveform and display it on the screen. The oscilloscope will continue to collect data, and when triggered again, the screen will update to the current new waveform.
- Single time: When the amplitude of the collected signal reaches the set triggering level, the triggering system will lock the waveform and display it on the screen. The system will stop collecting and display STOP; To trigger again, press the RUN key to start waiting for the next trigger.
- Trigger edge: Press the MENU key to pop up the setting window, and then press the direction key to select the trigger edge option left and right. The direction keys up and down are used to select different trigger edges, with up and down options.
-
- Rising edge: When the trigger system recognizes a signal that changes from small to large and reaches the set trigger voltage, the trigger is successful.
- Falling edge: When the triggering system recognizes the signal changes from large to small and reaches the set triggering voltage, the trigger is successful.
-
- Coupling method:
Press the FUNC key, select the far right menu option at the bottom of the screen, and display it as DC or AC. Press the direction keys to switch up and down; It is recommended to choose DC coupling when measuring DC signals and AC coupling when measuring AC signals. - Coupling method:
Press the FUNC key, select the far right menu option at the bottom of the screen, and display it as DC or AC. Press the direction keys to switch up and down; It is recommended to choose DC coupling when measuring DC signals and AC coupling when measuring AC signals. - Attenuation:
Press the MENU key to pop up the settings window, and then press the arrow keys to select the attenuation option left and right. The arrow keys up and down are used to select the x1 or x10 attenuation ratio. It is recommended to choose x1 attenuation ratio when the measured signal is less than ± 40V, and the x10 attenuation ratio when the signal is greater than ± 40V. The maximum input signal of the oscilloscope should not exceed ± 300V.
System settings:
Press the MENU key in oscilloscope mode to enter or exit menu mode; In menu mode, press the arrow keys left and right to select menu items, and press the arrow keys up and down to adjust the settings.
- Low power mode:
When the low-power mode is set to off, the screen brightness remains constant, that is, the brightness remains unchanged according to the set value; When set to on, there is no operation within 1 minute, and the screen brightness is automatically dimmed to save power. - Restore default:
After restoring the default operation, all menu settings will be restored to the factory default values, and the USB flash drive will also be formatted. - Saving images and exporting:
Long press and hold the SAVE key for 2 seconds, and the current screen display will be saved as an image in the device. To view saved images, you need to connect the device to the computer via USB and view it on the computer.- Select the export option in the menu, and the screen displays “USB MODE”.
- Use a TYPE-C data cable to connect the device to the computer, and generate a USB drive with the “O1_DISK” drive letter on the computer.
- Open the ‘PHOTO’ file to view the image.
- Exit USB mode and press the up button of the directional key.
- Self-calibration:
When there is a deviation in the baseline due to a large environmental temperature deviation or prolonged unused use, baseline calibration can be performed before use. Do not insert a probe or input signal during baseline calibration, as it may cause deviation. - Waveform output:
The signal output port outputs a fixed square wave signal with a parameter of 3V/1KHz. Please pay attention to the positive and negative polarity during measurement and avoid contact with metal parts. (Subsequent versions will upgrade to support sine wave, triangular wave, and PWM waveforms without prior notice.)
Maintenance
- General maintenance
- Clean the meter casing regularly. Do not clean with chemical solvents
- Keep the meter input jack dry and clean.
- If the meter is abnormal, please stop using it and return it for calibration and maintenance.
- Replace the fuse
This meter has a replaceable fuse built-in. If the fuse is damaged, the instrument casing needs to be opened and replaced with a new fuse before use. The replaceable fuse model is 250V/10A, 5x20mm. Please be sure to proceed under the guidance of professional personnel. - Charge
When the device prompts low or low battery, please charge it first before using it- Shut down the meter and remove test leads.
- Remove the protection case.
- Plug the Type-C power cord into the charging port for charging, and the indicator light will be red during charging.
