## Long description

Unit UT-191T is a handheld universal multimeter designed for measuring DC and AC voltage, current and resistance. Compact and portable, it provides the basic diagnostic functions needed for electrical and electronic systems, making it suitable for troubleshooting circuits, testing batteries and checking components in field and workshop environments. The device is intended for general-purpose measurements by technicians, electricians and hobbyists requiring a lightweight, easy-to-operate instrument.
Advantages
The multimeter delivers clear numeric readings for DC/AC voltage, current and resistance on a single compact instrument, reducing the need for multiple tools. Its handheld form factor supports portability and use in confined spaces. Simple control layout and dial selection enable quick measurement setup, while built-in protection features help reduce the risk of damage during routine diagnostics. The device offers reliable basic functionality for everyday electrical testing tasks.
Suitable for
Measuring DC and AC voltage in circuits and power supplies
Checking current draw of components and small devices
Testing resistance of resistors, connections and wiring
Quick battery voltage checks and component troubleshooting
Field service, workshop diagnostics and hobby electronics projects
Key specifications
Measurement types: DC voltage, AC voltage, DC current, resistance
Form factor: handheld, portable casing
User interface: rotary selector and numeric display for readings
Input protection: basic overload protection for common measurement ranges
Power supply: battery-operated for standalone use
Typical applications: electrical troubleshooting, component testing, battery checks
How to use
Turn the rotary selector to the required measurement function and range before connecting the probe leads. Connect the black probe to the common terminal and the red probe to the input for the selected measurement. For voltage and resistance measurements, place the probes across the circuit points or component terminals; for current measurements, insert the multimeter in series with the load according to the specified current range. Observe the numeric display and select a higher range if the reading is out of range. Switch the instrument off and remove the probes when testing is complete. Follow basic safety practices: avoid live measurement of unknown high-voltage circuits without appropriate training and personal protective equipment.
Usage recommendations
Use the multimeter primarily for low- to medium-voltage DC/AC diagnostics and component testing. Verify the chosen range before measuring, and replace the battery when display contrast or measurement stability degrades. Keep probe insulation and connectors in good condition and store the instrument in a dry place to preserve accuracy and prolong service life.
