સલામતી માહિતી
Always adhere to safety precautions when using any electrical testing equipment. Failure to do so may result in injury or damage to the device.
- દરેક કાર્ય માટે ઉલ્લેખિત મહત્તમ ઇનપુટ મૂલ્યોને ઓળંગશો નહીં.
- માપન કરતા પહેલા ખાતરી કરો કે ટેસ્ટ લીડ્સ સારી સ્થિતિમાં છે અને યોગ્ય રીતે જોડાયેલા છે.
- વોલ્યુમ સાથે કામ કરતી વખતે સાવચેતી રાખોtag30V AC RMS, 42V પીક, અથવા 60V DC થી ઉપર, કારણ કે આ આંચકાનું જોખમ ઊભું કરે છે.
- જો મલ્ટિમીટર ક્ષતિગ્રસ્ત દેખાય અથવા કેસ ખુલ્લો હોય તો તેને ચલાવશો નહીં.
- પ્રતિકાર અથવા સાતત્ય માપતા પહેલા હંમેશા પરીક્ષણ હેઠળના સર્કિટથી પાવર ડિસ્કનેક્ટ કરો.
- Use the Non-Contact Voltage (NCV) function as an initial check, but always verify with direct contact measurements when safety is critical.

2. ટેસ્ટ લીડ્સને કનેક્ટ કરવું
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.
ઓપરેટિંગ સૂચનાઓ
The NJTY T3 Multimeter features an auto-ranging function, simplifying operation by automatically detecting the measurement type and range.
1. પાવર ચાલુ/બંધ
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 voltage, DC વોલ્યુમtage, 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 વોલ્યુમtage માપન
- Ensure the multimeter is powered on.
- ટેસ્ટ લીડ્સને સર્કિટ પોઈન્ટ સાથે જોડો જ્યાં વોલ્યુમtage needs to be measured. The multimeter will automatically detect AC or DC voltage.
- ભાગ વાંચોtage મૂલ્ય સ્ક્રીન પર પ્રદર્શિત થાય છે.

4. પ્રતિકાર માપન
- મહત્વપૂર્ણ: પ્રતિકાર માપતા પહેલા ખાતરી કરો કે સર્કિટ ડી-એનર્જાઇઝ્ડ છે.
- Connect the test leads across the component or circuit section where resistance is to be measured.
- The multimeter will display the resistance value in Ohms (Ω), Kilo-Ohms (KΩ), or Mega-Ohms (MΩ).

5. બિન-સંપર્ક વોલ્યુમtage (NCV) તપાસ
The NCV function allows for safe detection of live wires without direct contact.
- Press the NCV button (if available, or ensure NCV mode is active).
- Bring the NCV sensor at the top of the multimeter close to the wire or outlet.
- 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
આ ફંક્શન એસી સર્કિટમાં જીવંત વાયરને ઓળખવામાં મદદ કરે છે.
- Insert the red test probe into the socket or touch it to the wire you want to test.
- If the multimeter emits an alarm sound and the screen changes to indicate "LIVE", it signifies a live wire.

7. સાતત્ય પરીક્ષણ
- મહત્વપૂર્ણ: Ensure the circuit is de-energized before performing a continuity test.
- Connect the test leads across the component or wire to be tested.
- If continuity exists (resistance is low, typically below 50Ω), the multimeter will emit an audible beep.
8. ડેટા હોલ્ડ
Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold function.
૬.૨.૮. ફ્લેશલાઇટ અને બેકલાઇટ
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).
