## Long description

The RB-266 digital multimeter by RB is a handheld test instrument with a large LCD screen designed to deliver clear, easy-to-read measurements for electrical diagnostics. It offers basic multimeter functions — including voltage, current and resistance measurement — in a compact, portable format suitable for fieldwork, laboratory benches and home electronics tasks. The device is intended for routine checks, troubleshooting and verification of electrical circuits where a reliable, straightforward meter is required.
Advantages
The RB-266 combines a large, high-contrast LCD for improved readability with a compact handheld design that fits easily into tool kits or pockets. It provides the essential measurement modes needed for common electrical tasks while minimizing complexity, making it accessible for both professional technicians and hobbyists. Built for on-site use, the meter offers fast response to input changes and clear numeric output to speed up diagnostics and reduce user error.
Suitable for
 Voltage checks on DC and AC circuits
 Basic current measurements in low-voltage systems
 Resistance and continuity testing of components and wiring
 Troubleshooting household appliances and electronic devices
 Field maintenance and quick verification tasks
Key specifications
 Form factor: handheld, portable design
 Display: large LCD screen for clear numeric readings
 Measurement functions: voltage (AC/DC), current (DC/limited AC depending on model), resistance, continuity
 Measurement range: covers common low-voltage ranges used in electronics and maintenance work
 Input protection: basic overload protection for typical workshop use
 Power: battery-powered for portable operation
 User interface: rotary selector and simple input jacks for probes
How to use
Before taking measurements, insert batteries and connect the appropriate test probes to the meter’s input jacks. Select the required measurement mode and range using the rotary selector; for unknown voltages start with the highest range and then step down to obtain a precise reading. Observe polarity when measuring DC voltage and current. When measuring current, open the circuit and place the meter in series with the load as required, or use the dedicated current input if provided. Follow standard safety procedures: remove power when measuring resistance or continuity, and avoid contact with live exposed conductors. Read values from the large LCD and hold or note readings as necessary.
Usage recommendations
The RB-266 is best used for routine checks and troubleshooting on low-voltage electronics, household electrical systems and equipment maintenance. Use insulated probes rated for the voltages you expect to measure, verify battery condition regularly to ensure accurate readings, and store the meter in a protective case to prevent screen damage. For high-voltage or specialized measurements, use instruments rated for those tasks.
