Universal meter with TRUE RMS function and automatic range for each measurement. It counts as many as 25000 digits. Allows you to perform basic and advanced measurements of electrical quantities. The large multifunction LCD display, a number of functions to facilitate measurements, wide measurement ranges, speed of operation and industrial precision will be appreciated by electronic engineers, electricians and home do-it-yourselfers alike. The rugged case is retrofitted with a red PVC holster with a non-slip structure, with dedicated places for measuring probes. The holster reduces the risk of slipping from hands and mitigates the effects of falls. The leads of the measurement probes have silicone insulation, which is flexible and resistant to high temperatures.

Basic measurements:

• AC voltage measurement: A.C. 0-750V, TRUE RMS (40-1000Hz)
• DC voltage measurement: D.C. 0-1000V
• alternating current measurement: A.C. 0-20A, TRUE RMS (40-1000Hz)
• DC current measurement: D.C. 0-20A
• resistance measurement: 0-250MΩ
• diode test:_IF 1.8mA,_UR 3.2V
• circuit continuity test: 0-50Ω

Additional measurements:

• AC+DC voltage measurement : 1-1000V
• capacitor measurement: 0-99.99mF
• frequency measurement: 0-10Mhz
• fill factor measurement: 1-99%
• temperature measurement: -20 to 1000°C
• 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-730895 meter for this range is : ±(0.3% + 3), resolution 0.1V
• calculation of measurement error formula: (measurement result x 0.3%) + 3 x resolution
• calculation: (235 x 0.3%) + 3 x 0.1 = 0.705 + 0.3 = 1.005V

Actual result including measurement error for 235V indication = 235 ± 1.005V

• Result including measurement error for DC voltage measurement indication: 12V = 12 ± 0.009V
• result including measurement error for AC current measurement indication: 8A = 8 ± 0.067A

A table with the resolution and accuracy for the measurement can be found in the user's manual.

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
• 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
• SEL - changing the measurement mode, e.g. from AC to DC voltage measurement
• MAX/MIN - retaining on the display the maximum or minimum value from the current measurement
• HOLD - retaining the currently measured value on the display
