Pornire/Oprire
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.
Instrucțiuni de operare
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.

Măsurarea AC/DC Voltage
Pentru a măsura voltage, ensure the multimeter is powered on. The device will automatically detect AC or DC voltage. Insert the red test lead into the positive terminal and the black test lead into the negative terminal or ground point of the circuit.

Funcția de păstrare a datelor
Press the "HOLD" button to freeze the current reading on the display. This is useful for recording measurements in difficult-to-read situations. Press "HOLD" again to release the reading.
Flashlight and Backlight
The multimeter includes a built-in flashlight to illuminate dark work areas. The color LCD display also features a backlight for clear visibility in low-light conditions. Refer to the device's buttons for activating these features.
