Key Features & Design Highlights
Compact & Ergonomics Design
The UNI-T digital multimeters feature a compact and ergonomic design, with dimensions of 182mm x 91mm x 45mm. Specific improvements include a 7mm (approx. 12%) reduction in thickness and a 4mm (approx. 4%) reduction in height and width compared to previous models, enhancing portability and user comfort.
Fast Measurement
The multimeters offer fast measurement capabilities, ensuring quick and accurate readings for efficient workflow.
Bias Frequency Measurement
This feature allows measurement of bias signals, crucial for applications like crystal oscillator frequency measurement in electronic product manufacturing and maintenance. The diagrams illustrate capturing a 'Normal signal' and a 'Bias signal' on an oscilloscope, showing how the UT15B/17B/18B MAX series provides correct measurements where a competitor's device may fail.
Mis-plug Alarm (LED)
An audible and visual LED alarm alerts the user if the test probes are connected to the wrong input jacks, preventing potential damage or incorrect readings.
Full Range Input Protection
The devices are equipped with full-range input protection, featuring two fast-acting fuses (e.g., DMM-17AR, DMM-44/100-R) and 1000V input protection for enhanced safety during operation.
Using Scenarios
The multimeters are versatile and suitable for various applications:
- Voltage Measurement (AC): Demonstrates the multimeter being used to measure AC voltage.
- VFD Function (Frequency): Shows the multimeter measuring frequency for Variable Frequency Drive (VFD) applications.
- LED Test (UT18B MAX only): Illustrates the LED test function, available on the UT18B MAX model.
- Temperature Measurement (UT17B/18B MAX): Depicts the multimeter measuring temperature, a feature available on the UT17B and UT18B MAX models.
Included accessories include a user manual, two pairs of test leads (normal gold-plated probe and fine-tipped probe), and optionally a K-type thermocouple for UT17B/18B MAX models, along with batteries and a magnetic hanger.
