Product Description from the Supplier

Xi'an Mingxi Taida Information Technology Co., Ltd. brings over 12 years of industry expertise to deliver cutting-edge measurement and control solutions.With progressed computerization forms and strict quality control, we guarantee each item meets the most noteworthy guidelines for proficient applications.

Description

The residual voltage remaining after power is cut off in large capacitive electrical equipment. Ordinary multimeters, with their high input impedance, cannot detect this residual voltage, leading to misjudgments, equipment malfunctions, or safety hazards. The UT171 series' Low Impedance (LoZ) function effectively solves this problem.

Features of the UT171B Programmable Industrial Multimeter

•True RMS measurement

True RMS measurement technology is one of the core features of the UT171B. Compared to traditional average response multimeters, true RMS multimeters can accurately measure non-sinusoidal waveforms that contain harmonics and distortion, which is especially important in modern industrial environments—the waveforms generated by devices such as motor drives, frequency converters, and switching power supplies are often not pure sine waves.

True RMS vs. Average Response

•​​​​​​​Low Impedance (LoZ) Mode

The UT171B's AC LoZ (low impedance AC voltage measurement) function features an input impedance of approximately 3kΩ, a characteristic crucial for eliminating "ghost voltage".

•VFC low-pass filter function

Built-in VFC (Variable Frequency Control) low-pass filtering is a key technology for measuring inverter output. Inverters use pulse width modulation (PWM) technology, and their output waveform contains a large number of high-order harmonics, which will cause unstable readings when measured with a regular multimeter.

The VFC function provides stable and accurate voltage and frequency measurements by filtering out high-frequency noise components above the power frequency. It is particularly suitable for:

•Variable frequency motor drive system testing

•VFD (Variable Frequency Drive) output measurement

•Industrial automation control system debugging

•EBTN black background with white text display

The UT171B uses EBTN liquid crystal display technology, which has the following advantages compared to traditional STN liquid crystal displays:

The display screen measures 70.6mm × 35.3mm and features a 31-segment analog bar chart, providing a perfect blend of the visual experience of an analog pointer instrument and the precision of a digital instrument.

Large-Capacity Data Storage

The UT171B Programmable Industrial Multimeter has a built-in data storage capacity of 9999 records and supports:

• Manual saving of key measurement data
• Automatic recording of measurement sequences
• Data recording with timestamps (requires PC software)

Rechargeable lithium battery system

The UT171B uses a 7.4V / 1800mAh rechargeable lithium battery, which has the following advantages compared to traditional alkaline batteries.

• Long battery life: Supports extended continuous use
• Convenient charging: Comes with a dedicated power adapter
• Cost-effective: Rechargeable
• Battery level display: Low battery warning function

Multiple data transmission methods

Comparison of Three Models in The UT171 Series

Special measurement functions:

• Conductivity measurement
• Loop measurement

The 4~20mA current loop is the most standard analog signal transmission method in industrial automation. Two-wire transmitters convert physical quantities into 4~20mA current signals, offering advantages such as strong anti-interference capability, long transmission distance, and convenient fault diagnosis.

• Diode testing - Determine the quality of a diode by detecting its forward voltage drop
• Continuity test - Quickly determine the continuity of a circuit
• Duty Cycle
• NCV non-contact voltage detection
• AC+DC Composite measurement

Simultaneous measurement of both AC and DC components in a signal, suitable for:

Rectifier circuit output measurement.Switching power supply output analysis.AC signals with DC bias.

• Peak Hold - Capture transient voltage/current peaks

Key Usage Tips

✅Do not exceed the range: The measured signal must not exceed the specified limit value to prevent electric shock and damage to the instrument

✅Do not change ranges while the instrument is powered on: Changing the range switch during measurement is strictly prohibited to prevent damage to the instrument

✅Proper power disconnection: After each measurement operation, disconnect the test leads from the circuit being measured; after completing current measurement, turn off the power supply before disconnecting the test leads

✅High voltage warning: Exercise caution when measuring voltages higher than 30V DC or 30Vrms AC to prevent electric shock

✅Temperature and Humidity: Do not use in high temperature and high humidity environments, and especially do not store in humid environments

✅Internal Wiring: Do not arbitrarily change the internal wiring of the instrument to avoid damaging the instrument and endangering safety

FAQs:

Q: What should I do if the measured values ​​fluctuate greatly?

A: Confirm if VFC mode is enabled (recommended when measuring inverter output). Switch to manual range and select an appropriate range. Enable the data hold function and read the stable value.

Q: NCV detection is insensitive?

A: Check the battery level; low battery levels will decrease NCV sensitivity. Also, ensure the detection location is close to an AC voltage source.
