A universal meter with TRUE RMS function and automatic range for each measurement. Counts up to 25,000 digits. Allows to perform basic and advanced measurements of electrical quantities.

Large multifunction LCD display, a number of functions facilitating measurements, wide measurement ranges, speed of operation and industrial precision will be appreciated by electronics engineers, electricians and home DIY enthusiasts. Solid housing equipped with a red PVC holster with an anti-slip structure, with dedicated places for measurement probes. The holster reduces the risk of the meter slipping out of your hands and reduces the effects of a fall. The measurement probe leads have silicone, flexible and high-temperature resistant insulation.

Basic measurements:

AC voltage: 0-750 V, TRUE RMS (40-1000 Hz)
DC voltage: D.C. 0-1000 V
AC current intensity: A.C. 0-20 A, TRUE RMS (40-1000 Hz)
DC current intensity: D.C. 0-20 A
resistance: 0-250 M
diode test: IF 1.8 mA, UR 3.2 V
continuity test: 0-50
Additional measurements:

AC+DC voltage: 1-1000 V
capacitor capacitance: 0-99.99 mF
frequencies: 0-10 Mhz
fill factor: 1-99%
temperatures: -20 to 1000C
non-contact AC voltage detection: NCV
Measurement accuracy:

Example of determining accuracy for AC voltage measurement. Calculations for the measurement result: 235 V

the measurement accuracy of the YT-730895 meter for this range is: (0.3% + 3), resolution 0.1 V
calculations of the measurement error formula: (measurement result x 0.3%) + 3 x resolution
calculations: (235 x 0.3%) + 3 x 0.1 = 0.705 + 0.3 = 1.005 V
Actual result taking into account the measurement error for the 235 V indication = 235 1.005 V

result taking into account the measurement error for the DC voltage measurement indication: 12 V = 12 0.009 V
result taking into account the measurement error for the AC current measurement indication: 8 A = 8 0.067 A
The table with the resolution and accuracy for a given measurement can be found in the user manual.

Functions:

TRUE RMS - the meter displays the true effective value of the alternating voltage/current. Unlike averaging meters, devices with TRUE RMS display the correct value not only for a sinusoidal waveform, but also for distorted sinusoidal waveforms, e.g. higher harmonics or square or triangular waveforms. A mandatory function wherever there are switching power supplies, motor inverter drives, HVAC installations, etc. in the circuit.
NCV - non-contact detection of alternating voltage by inductive method. The meter detects the presence of voltage in an insulated wire using the NCV sensor on the front of the device
AUTO - automatic adjustment of the measurement range (one measurement is enough), activated by default. In the case of measuring unknown values using a meter with manual range change using the knob, measurements should be performed successively from the largest range to the range giving the most accurate result - otherwise we risk damaging the device.
RANGE - manual change of measurement range, useful when checking many identical components with known values, e.g. a series of resistors. Manual setting of the range will significantly shorten the time of such measurements
REL - using the function during measurement will zero the display and accept the value visible before the display as the reference level. The next measurement will show the difference between the measured value and the stored reference value
SEL - change of measurement mode, e.g. from AC to DC voltage measurement
MAX/MIN - save the maximum or minimum value from the current measurement on the display
HOLD - save the currently measured value on the display
