It allows to perform basic and advanced measurements of electrical quantities. Using the measuring clamps, you can measure both direct and alternating current in the range from 10 mA to 1000 A. The measurement is performed without the need to disconnect the circuit or disconnect it from the power source. The meter allows you to measure significantly higher current than conventional electrical meters. The test probe leads have silicone, flexible and high-temperature resistant insulation. Basic measurements: AC voltage measurement: A.C. 0-750 V, TRUE RMS (40-1000 Hz) DC voltage measurement: D.C. 0-1000 V AC current measurement: A.C. 0-1000 A, TRUE RMS (40-1000 Hz) DC current measurement: D.C. 0-1000 A resistance measurement: 0-60 M diode test: IF 2 mA, UR 3.2 V continuity test: 0-50 Additional measurements: capacitor capacitance measurement: 0-100 mF frequency measurement: 0-10 Mhz temperature measurement: -30 to 1000 C non-contact AC voltage detection: NCV inrush current measurement phase presence measurement (probe function) Measurement accuracy: Example of determining accuracy for AC current measurement. Calculations for measurement result: 30 A measurement accuracy of the YT-730933 meter for this range is: (2.5%+10), resolution 0.01 A measurement error calculation formula: (measurement result x 2%) + 30 x resolution calculations: (30 x 2.5%) + 10 x 0.01 = 0.75 + 0.1 = 0.85 A Actual result taking into account the measurement error for the 30 A indication = 30 0.85 A. result taking into account the measurement error for the AC voltage measurement indication: 235 V = 235 2.85 V result taking into account the measurement error for the DC voltage measurement indication: 12 V = 12 0.146 V The 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 displays the true effective value of the alternating voltage or 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 using the inductive method. The meter detects the presence of voltage in an insulated wire, it can also indicate the phase wire. LINE - contact detection of alternating voltage, works like a traditional tester. After inserting the measuring probe into the hole in the socket, in the case of the presence of a phase, four lines will appear on the display, the signal diode will light up and an intermittent sound signal will be emitted. AUTO - automatic adjustment of the measurement range. When measuring unknown values using a meter with manual range adjustment using the knob, measurements should be taken successively from the largest range to the most accurate. Otherwise, we risk damaging the device. However, in the case of a multimeter with the AUTO function, it is enough to take one measurement and the meter will automatically find the optimal range. The meter starts in AUTO mode by default. RAN - manual change of the measurement range DATA HOLD - saving the currently measured value on the display INR - measurement of the starting current using measuring clamps. The meter will measure the starting current 80 ms after starting the device. Additional information:LCD display, maximum displayed result: 6000 backlighting of the screen and the clamp measuring field sound signal in the continuity test for resistance below 50 clamps open to 25 mm measuring probes 14 cm long length of the cable with probes: 103 cm diameter of the cable with insulation: 3.6 mm cover included design with overload protection automatic shutdown of the meter after 15 minutes of inactivity possibility of turning off the automatic shutdown mode of the device low battery indicator power supply: three 1.5 V (AAA) batteries Note! Current intensity measurement using clamp meters is performed only and exclusively on a single core, a single wire. Fastening the clamps to a multi-core cable without isolating a single core will show an incorrect result or zero current flow
