Multifunction Digital Multimeter | Signal Generator | 2-Channel Oscilloscope | 2x10MHz | 50MS/s | 1Hz-2MHz

Portable 3-in-1 digital measuring instrument – 2-channel oscilloscope, multimeter and signal generator, 2×10 MHz, 50 MS/s, 2.8″ display

Portable 3-in-1 digital measuring instrument combines a two-channel oscilloscope, a digital multimeter and a single-channel function signal generator. One instrument can be used to observe electrical signal waveforms, measure the main electrical quantities and generate test signals for electronics, automation, repair and training work.

The oscilloscope has two independent measurement channels, a real-time sampling rate of up to 50 MS/s and, according to the more detailed supplied specification, a 2×10 MHz analogue bandwidth. The integrated signal generator produces seven types of signals from 1 Hz to 2 MHz, while the multimeter is intended for measuring voltage, current, resistance, capacitance, temperature and other parameters.

• Sine wave — for testing analogue and audio circuits.
• Square wave — for testing digital circuits, pulses and timing.
• Triangle wave — for analysing linear circuits and integrators.
• Full-wave signal — for rectifier and signal-processing tests.
• Half-wave signal — for testing half-wave rectifier circuits.
• Noise signal — for evaluating the response of filters and amplifiers.
• DC signal — for generating a constant control-voltage level.

• Battery: 3000 mAh lithium battery.
• Charging connector: USB Type-C.
• Charging parameters: 5 V / 1 A.
• Stated operating time: up to 6 hours under laboratory conditions.
• Actual operating time: depends on display brightness and the functions being used.

• Three functions in one instrument — fewer separate measuring tools.
• Two oscilloscope channels — for observing two signals simultaneously.
• 50 MS/s sampling rate — for real-time signal capture.
• 2×10 MHz analogue bandwidth — for electronics and automation signals.
• 32 KB memory depth — for storing the captured waveform.
• Seven generator signal types — for various circuit tests.
• 1 Hz–2 MHz generator range.
• True RMS multimeter — according to the supplied product information.
• 9999-count display.
• Automatic ranging.
• Waveform and screenshot saving.
• USB Type-C charging.
• Integrated 3000 mAh battery.
• Compact portable enclosure.

• In electronics repair — for diagnosing circuit boards, power supplies and signal circuits.
• In industrial automation — for checking signals from sensors, controllers and actuators.
• In automotive electronics — for analysing low-voltage signals and sensors.
• In audio equipment — for testing audio signals, amplifiers and filters.
• In power-supply diagnostics — for observing ripple and output stability.
• In digital circuits — for checking pulses, frequency and logic signals.
• In training laboratories — for demonstrating waveforms and measurement principles.
• In field repair work — when a compact self-powered instrument is required.
• In amateur radio work — for investigating generator, filter and receiver circuits.
• In household-appliance repair — for checking control boards and power circuits.

For example, a controller PWM output used to regulate fan speed is being checked. Oscilloscope channel CH1 is connected to the control signal, while CH2 is connected to the fan supply or feedback signal.

Both signals can be observed on the display simultaneously, allowing their frequency, amplitude and response time to be compared. The trigger mode is set to the rising or falling signal edge.

In multimeter mode, the supply voltage and circuit resistance are checked. If the controller input needs to be tested, the signal generator is used to produce a square-wave or sine-wave test signal of the appropriate frequency.

The detected waveform can be saved and later viewed on a computer or compared with the signal after repair.

1. Check the condition of the instrument and accessories. Do not use damaged probes, leads or insulation.
2. Switch on the instrument. Check the battery charge level.
3. Select the function. Set the oscilloscope, multimeter or generator mode.
4. Select the correct sockets. Connect the test leads according to the selected multimeter or oscilloscope function.
5. Start with the highest range. If the voltage or current being measured is unknown, start with the highest permitted value.
6. In oscilloscope mode, set the probe factor. The instrument's ×1 or ×10 setting must match the probe being used.
7. Select AC or DC coupling. Set it according to the nature of the measured signal.
8. Set the time base and sensitivity. The waveform must fit on the display.
9. Select the trigger mode. Use AUTO, NORMAL or SINGLE mode.
10. Set the signal in generator mode. Select the waveform, frequency, amplitude and duty cycle.
11. Do not exceed the generator output load. Connect the generator only to a suitable high-impedance input circuit.
12. Save the required waveform. Use the SAVE function.
13. After completing the work, disconnect the leads safely. First disconnect the measurement signal, then switch off the instrument.

• Switch off the instrument before cleaning.
• Disconnect all probes, leads and the charging cable.
• Clean the enclosure with a dry or only slightly damp soft cloth.
• Do not allow liquid to enter the connectors or sockets.
• Do not use solvents, petrol or abrasive cleaners.
• Regularly inspect the insulation of the test leads.
• Check the current-input fuses.
• Periodically recharge the battery if the instrument is not used for a long time.
• Store in a dry place protected from heat and direct sunlight.

• Do not use the instrument in a damp or explosive environment.
• Do not touch uninsulated conductors or the metal parts of probes.
• Do not exceed the voltage limits marked on the instrument and leads.
• Before measuring, check the selected function and socket.
• Do not measure voltage while a lead is connected to a current-measurement socket.
• Measure capacitance, resistance and diodes only in a de-energised circuit.
• Discharge the capacitor before measuring capacitance.
• The common-point circuit of the oscilloscope inputs must be checked before mains measurements.
• Do not regard the two channels as galvanically isolated without technical confirmation.
• The ±400 V value is not permission to measure mains circuits under all conditions.
• The generator output is not protected as a power source.
• Do not apply an external voltage to the generator output.
• Use only suitable probes and test leads.
• Do not use the instrument if the enclosure or display is damaged.
• High-voltage work must be carried out by a qualified specialist.
