Features

True RMS measurement: The UT-203R measures true RMS voltage and current, which is important for accurate measurements of non-sinusoidal waveforms.
Auto-ranging: The meter automatically selects the correct range for the measurement, which saves time and prevents errors.
NCV: The NCV function allows you to detect the presence of live voltage without making contact, which is a safety feature.
Continuity test: The continuity test function allows you to check for the presence of a circuit path, which is useful for troubleshooting electrical problems.
Diode test: The diode test function allows you to check the polarity and forward voltage of a diode, which is useful for testing electronic components.
MAX/MIN: The MAX/MIN function records the maximum and minimum values of a measurement, which is useful for capturing transient signals.
Relative mode: The relative mode allows you to measure the difference between two readings, which is useful for making precise measurements.
Zero mode: The zero mode allows you to zero the meter to the current value, which is useful for making accurate measurements of small currents.
Data hold: The data hold function allows you to freeze the display of a measurement, which is useful for making detailed observations.
Low battery indication: The low battery indication alerts you when the batteries are running low, so you can replace them before the meter dies.
Auto power off: The auto power off feature turns off the meter after a period of inactivity, which saves battery life.
