Digital multimeter true rms lcd 4000 (YT-730894)

Universal meter with TRUE RMS function and automatic range for each measurement. Allows you to perform basic and advanced measurements of electrical quantities. Small size meter with large backlit LCD display and fast and precise measurement system. Robust housing retrofitted with a red PVC holster. It reduces both the risk of damage during a fall and, thanks to its non-slip stucture, slipping out of hands.

Basic measurements:

• AC voltage measurement: A.C. 0-600V, TRUE RMS (40-1000Hz)
• DC voltage measurement: D.C. 0-600V
• alternating current measurement: A.C. 0-10A, TRUE RMS (40-1000Hz)
• DC current measurement: D.C. 0-10A
• resistance measurement: 0-40MΩ
• diode test:_IF 0.3mA,_UR 2.3V
• circuit continuity test: 0-50Ω

Additional measurements:

• frequency measurement: 0-3Mhz
• non-contact AC voltage detection: NCV

Measurement accuracy:

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

• Measurement accuracy of YT-730894 meter for this range is : ±(1% + 3), resolution 0.1V
• calculation of measurement error formula: (measurement result x 1%) + 3 x resolution
• calculation: (235 x 1%) + 3 x 0.1 = 2.35 + 0.3 = 2.65V

Actual result including measurement error for 235V indication = 235 ± 2.65V

• The result including the measurement error for the DC voltage measurement indication: 12V = 12 ± 0.09V
• result including measurement error for AC current measurement indication: 8A = 8 ± 0.15A

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 switching power supplies, motor inverter drives, HVAC systems, etc. appear in a circuit.
• NCV - non-contact AC voltage detection by inductive method. The meter detects the presence of voltage in an insulated conductor using the NCV sensor on the face of the device
• AUTO - automatic adjustment of the measurement range. When measuring unknown values with a meter with manual range adjustment using the dial, take 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
• SEL - change the measurement mode, for example, from AC to DC voltage measurement
• HOLD - keeping the currently measured value on the display
