YT-730893 universal meter with TRUE RMS function and automatic range for each measurement. It allows you to perform basic and advanced measurements of electrical quantities. A large multifunctional LCD display, a number of functions that facilitate measurements, speed of work and industrial precision will be appreciated by electronics, electricians and home DIY enthusiasts alike. The housing is equipped with a red rubber holster with dedicated places for measurement probes, thanks to which the meter does not easily slip out of your hands and minimizes the risk of damage during a fall. The test probe cables have silicone, flexible and high-temperature-resistant insulation.

MEASUREMENT ACCURACY

An example of determining accuracy for measuring AC voltage. Calculations for the measurement result: 235V

measurement accuracy of the YT-730893 meter for this range is: ±(0.3% + 3), resolution 0.1V
Measurement error calculation formula: (measurement result x 0.3%) + 3 x resolution
calculations: (235 x 0.3%) + 3 x 0.1 = 0.705 + 0.3 = 1.005V
The actual result taking into account the measurement error for the indication 235V = 235 ± 1.005V

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

BUILT-IN FUNCTIONS

TRUE RMS - a meter with this function calculates the real effective value of alternating voltage and current for both sinusoidal and non-sinusoidal waveforms. The device first measures the actual value of the sine wave at several time intervals → then squares the measurement results → sums them → calculates the average → and finally squares the average result. The measurement result is the real effective value of alternating voltage/current, even for a deformed sine wave or square wave.
NCV - non-contact detection of alternating voltage using the inductive method. The meter detects the presence of voltage in the insulated wire using the NCV sensor on the front of the device
AUTO - automatic adjustment of the measurement range. When measuring unknown values using a meter with a manual range change using a knob, measurements should be performed sequentially from the largest range to the range giving the most accurate result - otherwise you risk damaging the device. However, in the case of a multimeter with the AUTO function, it is enough to perform one measurement and the meter will automatically find the optimal range. By default, the meter starts in AUTO mode
RANGE - manual change of the measurement range. A useful function when checking many of the same components with a known value, e.g. a series of resistors. Manually setting the range will significantly shorten the time of such measurements
REL - using the function during measurement will reset the display to zero and adopt 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
MAX/MIN - keeping the maximum or minimum value from the current measurement on the display
HZ % - the button when setting the knob to the frequency measurement position will change the settings to measurement of duty cycle/duty factor
SELECT - changing the measurement mode, e.g. from AC to DC voltage measurement
DATA HOLD - keeping the currently measured value on the display
