3.2. NJTY Non-Contact Voltage Tester Setup
નોન-કોન્ટેક્ટ વોલ્યુમtage Tester is typically powered by internal batteries. Ensure they are properly installed or charged if rechargeable.
- પાવર ચાલુ: Press the power button to turn on the device. A self-test may occur.
4. ઓપરેટિંગ સૂચનાઓ
4.1. NJTY T3 Digital Multimeter Operation
The multimeter features an auto-function scan for ease of use.
- પાવર ચાલુ/બંધ: Press and hold the power button to turn the multimeter on or off.
- Auto Function Scan: The multimeter automatically detects the type of measurement (AC/DC voltage, resistance, continuity) when the test leads are connected to a circuit.
- માપન એસી/ડીસી વોલ્યુમtage: Connect the test leads across the circuit or component to measure voltage. The display will show the reading.
- સાતત્ય પરીક્ષણ: In continuity mode, the multimeter will emit an audible beep if the resistance between the two test points is below approximately 50Ω, indicating a continuous circuit.
- પ્રતિકાર માપન: Connect the test leads across the component to measure its resistance.
- NCV (બિન-સંપર્ક વોલ્યુમtage) શોધ: Move the top of the multimeter near an AC voltage source. The device will indicate the presence of voltagસીધા સંપર્ક વિના.
- ડેટા હોલ્ડ: ડિસ્પ્લે પર વર્તમાન રીડિંગ ફ્રીઝ કરવા માટે 'હોલ્ડ' બટન દબાવો. રિલીઝ કરવા માટે ફરીથી દબાવો.
- Flashlight/Backlight: The multimeter includes a built-in flashlight and backlight for improved visibility in dark environments.

4.2. NJTY Non-Contact Voltagઇ ટેસ્ટર ઓપરેશન
ભાગtage tester is designed for quick and safe voltage શોધ.
- NCV (બિન-સંપર્ક વોલ્યુમtage) શોધ: Place the tip of the tester near a wire or outlet. The device will indicate the presence of AC voltage through visual and audible alerts.
- સંવેદનશીલતા ગોઠવણ: The tester offers dual sensitivity ranges (12-1000V and 48-1000V). Use the sensitivity button to switch between low and high sensitivity modes as needed for different applications.
- Live/Neutral Wire Identification: The tester uses voice alerts to audibly distinguish between live (hot) and neutral wires, enhancing safety and ease of identification.
- Break-Point Test: Use the tester to identify breaks in wires or cables. Move the tester along the wire; the absence of a signal indicates a break.
- Flashlight & Laser: The tester includes a built-in flashlight for illuminating work areas and a laser for precise alignment or pointing.

5. જાળવણી
- સફાઈ: Wipe the devices with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- સંગ્રહ: Store the bundle in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care (Multimeter): Recharge the multimeter regularly, especially if it will not be used for an extended period, to maintain battery health.
6. મુશ્કેલીનિવારણ
- ઉપકરણ ચાલુ નથી: Ensure the battery is charged (Multimeter) or properly installed (Voltage Tester).
- Inaccurate Readings (Multimeter): Check test lead connections. Ensure the correct measurement mode is selected (though auto-scan helps).
- No Detection (Voltage Tester): Ensure the device is powered on. Adjust sensitivity if necessary.
- તૂટક તૂટક ઓપરેશન: છૂટા કનેક્શન અથવા ઓછી બેટરી માટે તપાસો.
