Description

Functions of the UT89X NCV multimeter

•Supports dual-range NCV detection, quickly identifying live and neutral wires through light intensity.

•The neutral and live wires can be distinguished using only one probe (UT89X exclusive).

•True RMS technology ensures accurate measurement of non-sinusoidal signals.

•Capacitance measurement range up to 100mF, far exceeding that of products in the same price range.

•1-meter drop protection, IP54 protection rating, highly durable.

•UT89XD exclusive feature: can detect the quality of LEDs.

Model Function Comparison

Features

The UT89X series employs True RMS measurement technology, accurately measuring both sinusoidal and non-sinusoidal signals:

• Measurement Principle: Calculates the root mean square value of the signal directly from the sampled waveform data, rather than assuming an ideal sine wave.

• Applicable Scenarios: Circuits that generate harmonics, such as frequency converters, SCR dimming, and switching power supplies.

• Accuracy Advantage: Compared to average response multimeters, the measurement error for non-sinusoidal signals is more than 40% lower.

• The True RMS function performs stably when measuring the starting current of VFDs (Variable Frequency Drives) and clearly displays phase imbalance problems caused by harmonic distortion.

• Supporting dual-range NCV detection.

• Capacitor Charging Status Indicator: Dual-color LED displays charging progress

Input Protection Mechanism

Applications

The UT89X series is positioned above the UT890 series, with the main differences being

• AC voltage range extended to 1000V
• Capacitance measurement range extended to 100mF
• Addition of non-contact NCV voltage testing function
• Addition of Live single-probe testing function (UT89X)

Cautions- the UT89X NCV multimeter

• The mV range reading may be unstable when no load is connected; it will stabilize after a load is connected
• True RMS measurement, AC crest factor: full-scale value up to 3.0
• No additional error is added when the crest factor of non-sinusoidal waveforms is no greater than 3.0
• Audible and visual alarms will be triggered when the current is ≥10A
• Measuring time should not exceed 60 seconds within the range of 6~10A
• The interval between adjacent measurements should be no less than 1 minute
• The power supply to the circuit under test must be turned off before measuring resistance
• All capacitors must be fully discharged
• Resistance measurement of live circuits is prohibited
• Do not input voltages higher than 60V DC or 30V AC
• When measuring frequency, press the SEL/REL key to switch between frequency and duty cycle
• Only type K thermocouples can be connected
• The temperature of the object being measured must not exceed 230°C / 446°F
• Press the SEL/REL key to switch between Celsius and Fahrenheit
• Precautions: During testing, the transistor must be inserted into the corresponding transistor test port

• Pay attention to distinguishing between NPN and PNP types, and the E, B, and C terminals.

• Do not use if the battery cover or back cover is not properly closed

• Do not use if the test lead insulation is damaged

Software User Manual

• Data Hold Function (HOLD)
• Relative Value Measurement (REL)
• MAX/MIN Maximum/Minimum Value Measurement

Key Usage Tips
