Smart Auto Recognition and Measurement
The FNIRSI DMT-99 Digital Multimeter features intelligent automatic recognition, allowing it to identify and measure key parameters without manual range selection. This function makes it exceptionally easy to use, especially for beginners or users who need quick, efficient measurements. Once the test probes contact the circuit, the DMT-99 automatically determines the measurement type — such as voltage, resistance, or continuity — and displays the result instantly on the screen.
This automation eliminates guesswork and simplifies operation, reducing the risk of user error while speeding up diagnostic processes. The combination of smart detection and responsive processing ensures users can focus on analysis rather than manual settings, streamlining workflows for technicians and engineers alike.
Comprehensive Range of Measurements
The FNIRSI DMT-99 is equipped with a wide variety of testing functions, making it a versatile instrument for multiple applications. It measures:
-
AC/DC Voltage — for analyzing power circuits, battery systems, and household wiring.
-
AC/DC Current — for monitoring load flow and system performance.
-
Resistance — for component evaluation and circuit continuity checks.
-
Capacitance — to test capacitors, filters, and electronic circuits.
-
Frequency and Duty Cycle — ideal for signal and waveform analysis.
-
Continuity and Diode Tests — for verifying circuit integrity and component functionality.
-
Temperature Measurement — to detect thermal variations in equipment and components.
Each of these functions is supported by the DMT-99’s clear and intuitive display interface, ensuring all readings are visible, organized, and easy to interpret.
High-Definition Full-Color Display
One of the standout features of the FNIRSI DMT-99 Multimeter is its 2.8-inch intelligent color screen, designed to provide a clear, vivid display of data in real time. The color-coded interface enhances readability by distinguishing different measurement modes and alert states, making it easier to interpret results quickly and accurately.
The display is designed with wide viewing angles and adjustable brightness, ensuring visibility under various lighting conditions — from bright outdoor work sites to dimly lit laboratories. The graphical display layout also helps users identify key parameters, measurement units, and test conditions at a glance, improving overall efficiency and reducing eye strain during extended use.
True RMS for Accurate Readings
The FNIRSI DMT-99 utilizes True RMS (Root Mean Square) technology, which ensures that all readings are accurate even when dealing with irregular or distorted waveforms. This is particularly useful when testing modern electronic devices, power inverters, or variable frequency systems, where signals may not follow a pure sine wave pattern. The True RMS feature provides reliable readings of both AC voltage and current, giving professionals the confidence they need for demanding measurement tasks.
User-Friendly Interface and Smart Functions
Ease of use is at the heart of the DMT-99’s design. Its intelligent interface combines touch-sensitive buttons and a clearly labeled rotary switch, allowing for effortless function selection. The menu navigation is straightforward, ensuring both experts and beginners can operate it efficiently.
Key smart functions include:
-
Auto Range Selection: Automatically adjusts measurement range for optimal accuracy.
-
Data Hold Function: Allows users to freeze the current reading for later reference.
-
Max/Min Record: Captures peak measurement values for detailed analysis.
-
NCV (Non-Contact Voltage Detection): Quickly detects live wires or voltage presence without physical contact.
-
Auto Power-Off: Conserves energy by shutting down the device after a period of inactivity.
These intelligent features make the FNIRSI DMT-99 not only powerful but also exceptionally practical for everyday use.
Built-In Safety and Protection
The FNIRSI DMT-99 Multimeter is engineered with multiple layers of safety protection to ensure reliable operation in all environments. It includes overload protection on all measurement ranges, safeguarding the internal circuitry against accidental overvoltage or current surges. The device is constructed with high-quality, flame-retardant materials, providing resistance to shocks, drops, and environmental wear.
In addition, the multimeter features input protection for sensitive measurement modes and fuse protection for current measurements, minimizing the risk of damage. The insulated test leads and high-quality input jacks ensure a secure and safe connection, maintaining stability even under high-load conditions.
The integrated NCV detection function adds another layer of safety by allowing users to identify live electrical wires without making direct contact, reducing the risk of electric shock during troubleshooting and installation tasks.
Rugged and Portable Design
Designed for professional use, the FNIRSI DMT-99 features a sturdy yet compact construction that balances portability with durability. The ergonomic housing provides a comfortable grip, while the protective rubber casing helps absorb shocks and impacts. Its lightweight form factor makes it convenient for fieldwork, allowing technicians to carry and use it easily in different locations.
The back stand supports hands-free use on workbenches, allowing for stable viewing angles during extended testing sessions. This combination of form and function ensures the DMT-99 can handle daily professional demands in workshops, labs, and outdoor environments.
Long Battery Life and Power Efficiency
The FNIRSI DMT-99 operates on a rechargeable battery system, ensuring long hours of continuous use without frequent replacements. Its efficient power management system and auto power-off function help conserve energy, extending operational time between charges. This makes the device ideal for field technicians and users who need dependable performance during long work sessions.
