Author: abhi1408

Creation date:

Evaluation Type: Independent Products

Did you receive all parts the manufacturer stated would be included in the package?: True

What other parts do you consider comparable to this product?: "UNI-T UT161E" and UNI-T Products.

What were the biggest problems encountered?: The Default resistance value of the Adaptor is 10Kohm(This problem occurs only when the DMM Resistance range is set greater than 10Kohm.) Reproduction Steps: 1. Connect the adaptor to the DMM. 2. Set the DMM mode to Resistance. 3. Set the Range to Ohm. 4. Increase the range from ohn to 10Kohm. Observation: When the range is set to 10Kohm then the resistance value is displayed as 10.898. Expected: As the resistance is not connected, DMM should Display as 0 ohms.

Tips and tricks

Here are some tips and tricks for using a digital multimeter:

  1. Familiarize yourself with the different modes and settings: Most digital multimeters have a variety of modes and settings, including voltage, current, resistance, continuity, and diode testing. Make sure you know what each mode is used for and how to switch between them.

  2. Check the battery: Before you start using your multimeter, make sure the battery is fresh or fully charged. A dead battery can affect the accuracy of your readings.

  3. Read the manual: Make sure you read the manual carefully and understand how to use the multimeter safely.

  4. Use the correct probe: Some multimeters come with multiple probes for different types of measurements. Make sure you use the correct probe for the measurement you're taking.

  5. Set the correct range: When measuring voltage, current, or resistance, make sure you set the multimeter to the correct range(This product supports not only auto range but it supports manual mode as well.). This will help ensure accurate readings and prevent damage to the multimeter.

  6. Pay attention to polarity: When measuring voltage or current, make sure you connect the probes correctly. Reverse polarity can damage the multimeter and give you incorrect readings.

  7. Be safe: Always make sure you're aware of the electrical potential of the circuit you're testing, and take appropriate safety precautions, such as wearing gloves and eye protection.

Use Cases of DMM:

digital multimeter (DMM) is a precision instrument that offers advanced measurement capabilities and is used in a wide range of applications, including:

  1. Research and Development: High-end DMMs are commonly used in laboratory and research environments to measure and analyze electrical signals with high accuracy and precision.

  2. Quality Control and Testing: High-end DMMs are used in manufacturing and production environments to test and verify the quality of electrical components and systems, ensuring that they meet specified performance standards.

  3. Electrical Safety Testing: High-end DMMs are used to measure electrical safety parameters, such as insulation resistance and ground resistance, to ensure that electrical systems and equipment are safe to use.

  4. Power Quality Analysis: High-end DMMs are used to measure and analyze the quality of electrical power in a variety of applications, including renewable energy systems, industrial power systems, and residential power grids.

  5. Servicing and Maintenance: High-end DMMs are used to diagnose and repair complex electrical issues in a wide range of electronic devices and systems, including medical equipment, process control systems, and aerospace systems.

  6. Data Logging and Analysis: High-end DMMs can be connected to data logging software to collect and analyze large amounts of electrical measurement data over time, providing valuable insights into system performance and stability.

I have a few Tips for the Manufacturer/Developer for further improvements in this product to stand out from the competition.

Short Term (Delta Change): If there is a DLL supported for your device to read the values from DMM then this device can easily be integrated into the HIL setups (HIL setups to monitor) which would increase their customer base.

Long Term: The device needs to be controlled via software as well. (Currently, there is only one-way communication from the device to the PC. the device should also be software controlled)

A software-controlled digital multimeter (DMM) has several advantages over traditional, standalone DMMs:

  1. Increased functionality: Software-controlled DMMs can be programmed to perform more advanced measurement functions, such as data logging, statistical analysis, and waveform analysis.

  2. Increased accuracy: The software can be programmed to perform complex calculations, increasing the accuracy of the measurement.

  3. User-friendly interface: A software-controlled DMM can be controlled through a graphical user interface (GUI), making it easier for users to interact with the device and reducing the learning curve.

  4. Remote control: The software can be used to remotely control the DMM, allowing users to perform measurements from a safe distance or in hazardous environments.

  5. Data storage: The software can store measurement data for later analysis, providing a record of the measurement results that can be easily accessed and reviewed.

  6. Increased flexibility: A software-controlled DMM can be connected to a computer, which provides access to additional software tools and allows the device to be used in a wider range of applications.

  7. Cost-effectiveness: In many cases, a software-controlled DMM can be more cost-effective than traditional, standalone DMMs, as it can perform multiple functions with a single device.

  8. ARR(Annual Recurring Revenue): With the help of the Software, Complex features can be set as the subscription model which could generate revenue.

Waiting to get selected for the next Roadtest as well.

  • I have recentIy purchased one MPt30679, which is apparently a rebadged UTI-T UT161E.It works fine as a multimeter but I would much like to use its communication and recording features.  I have 2 questions and would much appreciate any assistance.  The UT161E apparently has a Bluetooth option but I can find no information on the UTI-T website. I have downloaded and apparently installed software for the UT161E from this website. Open the .exe file and it always seeks to update the computer registry, something that occurs once at instal time! It also cannot find the meter (connected using USB cable provided). Have reinstalled software, with no improvement. I receive no reply from messages to UTI-T.  Is there any knowledge of these two topics among forum members?  Harry Battam

  • Shouldn't the meter indicate infinity or over range when no resistance (extremely high resistance) is present? Some meters flash, some display underscores, some display 1 and blanks, some display OL. etc.
