Digital multimeter with true rms (YT-73085)

Universal meter YT-73085 with TRUE RMS function and automatic range for each measurement allows you to perform basic and advanced electrical measurements. In addition to the speed of its operation, its undoubted advantage is the possibility of using an additional accessory in the form of measuring clamps, such as YT-73090 to perform measurements of high currents.

Basic measurements:

• AC voltage measurement: A.C. 0-600 V, TRUE RMS
• DC voltage measurement: D.C. 0-600 V
• alternating current measurement: A.C. 0-10 A, TRUE RMS
• DC current measurement: D.C. 0-10 A
• resistance measurement: 0-60 MΩ
• diode test: IF 0.8 mA, UR 3.3 V
• circuit continuity test: 0-100 Ω

Additional measurements:

• capacitor measurement: 0-60 mF
• frequency measurement: 0-10 Mhz
• temperature measurement: -40 to 1370°C
• fill factor measurement: 0.1-99%
• hFe transistor test: 0-1000, detachable measurement adapter

Measurement accuracies:

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

• Measurement accuracy of YT-73085 meter for this range is : ±(1% + 8), resolution 0.1 V
• calculation of measurement error formula: (measurement result x 1%) + 8 x resolution
• calculation: (235 x 1%) + 8 x 0.1 = 2.35 + 0.8 = 3.15 V

Actual result including measurement error for 235 V indication = 235 ± 3.15 V

• Result including measurement error for DC voltage measurement indication: 12 V = 12 ± 0.126 V
• result including measurement error for AC current measurement indication: 8 A = 8 ± 0.3 A

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

Built-in 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 impulse power supplies, motor inverter drives, HVAC systems, etc. appear in a circuit.
• AUTO - automatic adjustment of the measurement range. When measuring unknown values with a meter with manual range adjustment using the knob, make 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
• SELECT - change of measurement mode, e.g. change from resistance measurement to diode test or continuity test of a circuit
• RELATIVE - using the function during a measurement will reset the display to zero and take the value shown before the display as the reference level. The next measurement will show the difference between the measured value and the retained reference value
• HZ/Duty - button when the knob is set to frequency measurement will change the setting to fill factor/cycle measurement
• DATA HOLD [H] - retaining on the display the currently measured value
• MAX/MIN - retaining on the display the maximum or minimum value from the current measurement

Additional information:

• LCD display, maximum displayed result: 5999
• backlighting of the screen
• audible signal in circuit continuity test for resistance below 50 Ω
• possibility to enable diode and circuit continuity tests separately
• included measuring probes, temperature probe, transistor test adapter
• design with overload protection
• ABS plastic housing + so-called holster, i.e. rubber casing to protect the meter from mechanical damage
• magnetic pendant allows the meter to be attached to a metal surface such as a car hood.
• automatic shutdown of the meter after 15 minutes
• low battery indicator
• power supply: 9 V (6F22) battery
