Universal meter, two-channel oscilloscope and basic waveform generator in one. It allows you to perform basic and advanced measurements of electrical quantities and visualize the tested signal in real time. The 3.5" IPS matrix color display guarantees readability from any angle. The replaceable 3400 mAh li-ion battery, rechargeable via the built-in usb-c port, is sufficient for about 6 hours of continuous operation. The multitude of additional functions, wide measurement ranges, speed of operation and high precision will be appreciated by electronic engineers, electricians and home do-it-yourselfers alike.

Basic parameters of the oscilloscope:

bandwidth: 50MHz
sampling frequency: 280MSa/s
acquisition memory: 128kpts
number of channels: 2
measurement probe support: x1 and x10
Selected oscilloscope functions:

AUTO - automatically and quickly obtain a stable waveform on the oscilloscope displayautomatically detect the time base and voltage of the signal under test
SAVE - saves a screenshot to .bmp graphic file format
TRIG - signal trigger modes
CURSOR - measurement lines, enables precise measurement of the value of the visualized waveform
PROBE - set the attenuation of the measuring probe x1 luv x10
MEASURE - display of measurements: frequency, period, voltages: rms, minimum, maximum, peak-to-peak
XY MODE - compares signals from two channels in terms of frequency and phase shifts and presents them in visual form (Lissajous patterns)
CALIBRATE - auto calibration function
STORAGE - device mode for transferring data, e.g. transferring saved screenshots to a computer
Basic measurements of the meter:

AC voltage measurement: A.C. 0-750V, TRUE RMS (40-1000Hz)
DC voltage measurement: D.C. 0-1000V
alternating current measurement: A.C. 0-10A, TRUE RMS (40-1000Hz)
DC current measurement: D.C. 0-10A
resistance measurement: 0-250M
diode test:IF 1.8mA,UR 3.2V
circuit continuity test: 0-50
Additional measurements of the meter:

capacitor measurement: 0-99.99mF
frequency measurement: 0-999.9Khz
Meter measurement accuracy:

Example of accuracy determination for AC voltage measurement. Calculation for the measurement result: 235V

Measurement accuracy of YT-730944 meter for this range is : (0.5% + 3), resolution 0.01V
calculation of measurement error formula: (measurement result x 0.5%) + 3 x resolution
calculation: (235 x 0.5%) + 3 x 0.01 = 1.175 + 0.03 = 1.205V
Actual result including measurement error for 235V indication = 235 1.205V

The result including the measurement error for the indication of measuring12*var of DC voltage: 12V = 12 0.009V
result including measurement error for indication of AC current measurement: 8A = 8 0.067A
A table with the resolution and accuracy for the measurement can be found in the instruction manual.

Meter functions:

TRUE RMS - a meter with this function displays the true rms value of AC voltage/voltage. Unlike averaging meters, devices with true rms show the correct value not only for sinusoidal waveforms, but also for sinusoidal waveforms distorted, such as by higher harmonics, or square or triangular waveforms. A must-have function wherever impulse power supplies, motor inverter drives, HVAC systems, etc. appear in a circuit.
AUTO - automatic adjustment of the measurement range. When measuring unknown values with a meter with manual range adjustment using the knob, make measurements sequentially from the largest range up to the range giving the most accurate result - otherwise you risk damaging the device. On the other hand, in the case of a multimeter with the AUTO function, you only need to make one measurement and the meter will automatically find the optimal range. The meter starts by default in AUTO mode
RANGE - manual change of the measurement range. A useful function when checking many of the same components with a known value, such as a series of resistors. Manual setting of the range will shorten the time of such measurements significantly
REL - using the function during a measurement will reset the display to zero and take the value seen before the display as the reference level. The next measurement will show the difference between the measured value and the retained reference value
MAX/MIN/AVG - retaining on the display the maximum, minimum and average value from the current measurement
HOLD/SAVE - retaining on the display the currently measured value, saving it to memory.
