සැලසුම

1. මූලික අයකිරීම

The NJTY T3 Multimeter features a built-in rechargeable Lithium Ion battery. Before first use, or if the low battery indicator is displayed, charge the device using the provided Type-C charging cable.

1. Connect the Type-C end of the charging cable to the multimeter's charging port.
2. Connect the USB-A end of the charging cable to a standard USB power adapter (not included) or a computer's USB port.
3. The charging indicator on the multimeter will illuminate during charging and turn off when fully charged.

2. පරීක්ෂණ මඟ පෙන්වීම් සම්බන්ධ කිරීම

Insert the red test lead into the "VΩ" input jack and the black test lead into the "COM" input jack. Ensure they are securely seated.

මෙහෙයුම් උපදෙස්

The NJTY T3 Multimeter features an auto-ranging function, simplifying operation by automatically detecting the measurement type and range.

1. බලය සක්‍රිය / අක්‍රිය කරන්න

Press and hold the power button to turn the multimeter on or off. The device will automatically shut off after approximately 15 minutes of inactivity to conserve battery life.

2. Automatic Measurement (Auto-Ranging)

In auto-ranging mode, the multimeter will automatically identify and measure AC voltagඊ, ඩීසී වෙළුමtage, or resistance when the test leads are applied to a circuit. The display will show the measurement type (AC, DC, Ω) and the value.

3. AC/DC වෙළුමtagඊ මැනීම

1. Ensure the multimeter is powered on.
2. පරීක්ෂණ ලීඩ් පරිපථ ලක්ෂ්‍යවලට සම්බන්ධ කරන්න, එහිදී වෝල්tage needs to be measured. The multimeter will automatically detect AC or DC voltage.
3. වෙළුම කියවන්නtage අගය තිරයේ දිස්වේ.

5. සම්බන්ධතා නොවන වෙළුමtage (NCV) හඳුනාගැනීම

The NCV function allows for safe detection of live wires without direct contact.

1. Press the NCV button (if available, or ensure NCV mode is active).
2. Bring the NCV sensor at the top of the multimeter close to the wire or outlet.
3. The multimeter will emit an audible beep and the display will indicate the presence of AC voltage, with increasing intensity as it gets closer to the source.

6. Live Wire Testing

This function helps identify live wires in an AC circuit.

1. Insert the red test probe into the socket or touch it to the wire you want to test.
2. If the multimeter emits an alarm sound and the screen changes to indicate "LIVE", it signifies a live wire.

2. Connect the test leads across the component or wire to be tested.
3. If continuity exists (resistance is low, typically below 50Ω), the multimeter will emit an audible beep.

8 දත්ත රඳවා තබා ගැනීම

Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold function.

9. Flashlight and Backlight

The multimeter includes a built-in flashlight for illuminating the test area and a backlight for the display, enhancing visibility in low-light conditions. Refer to the device buttons for activation (typically a short press of the power button or a dedicated light button).
