Укључивање/искључивање
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.
Упутство за употребу
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 voltagе, ДЦ волtage, or resistance) and selects the appropriate range. Simply connect the test leads to the circuit or component you wish to measure.

Меасуринг АЦ/ДЦ Волtage
За мерење волtage, 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.

Функција задржавања података
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.

Одржавање
Чишћење
За чишћење мултиметра користите меку,amp крпу. Не користите абразивна средства за чишћење или раствараче, јер могу оштетити цasing or display. Ensure the device is powered off and disconnected from any power source before cleaning.
Баттери Царе
The built-in rechargeable battery requires no specific maintenance other than regular charging when indicated. Avoid fully discharging the battery for extended periods to prolong its lifespan. The automatic shut-off feature helps conserve battery power.
Складиштење
Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it away from strong magnetic fields and corrosive substances.
Решавање проблема
| Проблем | Могући узрок | Решење |
|---|---|---|
| Мултиметар се не укључује. | Слаба или испражњена батерија. | Charge the multimeter using the Type-C charging cable. |
| Нетачна очитавања. | Improper connection of test leads; environmental interference. | Ensure test leads are securely connected. Avoid strong electromagnetic fields. |
| На дисплеју се приказује „OL“ (преоптерећење). | Measurement exceeds the device's maximum range. | Disconnect immediately. Do not attempt to measure values beyond the specified limits. |
| NCV function not responding. | NCV function not activated; no live voltagе пресент. | Ensure NCV mode is active. Test on a known live circuit to verify functionality. |
