Encendido/apagado
Press and hold the power button located on the side of the multimeter to turn it on or off. The device will automatically shut off after approximately 15 minutes of inactivity to conserve battery life.
Instrucións de funcionamento
The NJTY T3 features an auto-ranging function, simplifying measurements by automatically detecting the type and range of the input signal.
Automatic Recognition and Measurement
In its default "AUTO" mode, the multimeter intelligently identifies the measurement type (AC voltage, DC voltage, or resistance) and selects the appropriate range. Simply connect the test leads to the circuit or component you wish to measure.
