## Long description

The Uni-T UT15B MAX True RMS Digital Multimeter is a professional-grade measurement tool engineered for high precision and reliability in electrical diagnostics. This device provides accurate readings for a wide range of electrical parameters, making it an essential instrument for electricians, technicians, and electronics enthusiasts involved in the maintenance and troubleshooting of electrical circuits and equipment.
Advantages
This multimeter stands out due to its True RMS measurement capability, which ensures accurate results even when dealing with non-sinusoidal waveforms. The device is built with a robust housing and features a clear 6000-count display with adjustable backlighting for optimal visibility in various lighting conditions. Users benefit from versatile functionality, including automatic and manual range selection, data hold, and relative mode, which streamline complex measurement tasks. Furthermore, the inclusion of a VFD function allows for specialized testing in variable frequency drive circuits, while the integrated safety features, such as visual and audible alarms for incorrect lead connections, provide peace of mind during operation.
Suitable for
Troubleshooting residential and commercial electrical circuits
Testing and maintaining electronic components and equipment
Measuring voltage, current, resistance, and capacitance in laboratory or field settings
Working with variable frequency drive systems
Performing continuity and diode tests
This device may not be suitable for industrial environments requiring CAT IV safety ratings, as it is rated for CAT III 600V. Additionally, it does not include temperature measurement capabilities, so it is not the ideal choice for applications where thermal monitoring is a primary requirement.

Weight: 455 g
To use the Uni-T UT15B MAX, first insert the provided batteries into the rear compartment. Connect the appropriate test leads to the input jacks based on the parameter you intend to measure. Turn the rotary dial to the desired function. For voltage or current measurements, ensure the leads are connected to the correct ports to avoid triggering the wiring error alarm. Use the function buttons to toggle between modes such as Data Hold or relative measurements. The device will automatically shut down after a period of inactivity to preserve battery life, and it can be woken up by pressing any button.
What to consider before purchase
Verify that the CAT III 600V safety rating meets your specific workplace or project requirements.
Confirm that you do not require built-in temperature measurement functionality.
Ensure the measurement ranges for voltage, current, and capacitance align with your typical electrical tasks.
Always inspect your test leads for damage before each use and ensure they are inserted into the correct terminals to prevent damage to the multimeter or the circuit under test.
