2. حفاظت جي ڄاڻ

Always read and understand all safety warnings and operating instructions before using this multimeter. Failure to do so may result in injury or damage to the instrument.

• ڪنهن به حد لاءِ وڌ ۾ وڌ ان پٽ ويليوز کان وڌيڪ نه ڪريو.
• وول سان ڪم ڪرڻ وقت انتهائي احتياط استعمال ڪريوtag30V AC RMS، 42V چوٽي، يا 60V DC کان مٿي. اهي جلدtagاهو هڪ جھٽڪو جو خطرو آهي.
• Ensure the test leads are in good condition, without any damaged insulation.
• Always connect the common (black) test lead first, then the live (red) test lead. Disconnect the live test lead first.
• Do not use the multimeter if it appears damaged or is not operating correctly.
• جڏهن بيٽري جو گهٽ اشارو ظاهر ٿئي ته فوري طور تي بيٽريون تبديل ڪريو ته جيئن صحيح پڙهائي يقيني بڻائي سگهجي.

4.1 بيٽري لڳائڻ

The RuoShui 3010 requires 2 AAA batteries and 1 9V battery for operation. These are typically included.

1. ملٽي ميٽر جي پوئين پاسي بيٽري جي ڪمپارٽمينٽ ڪَوَر کي ڳوليو.
2. برقرار رکڻ واري اسڪرو کي کوليو ۽ ڍڪ هٽايو.
3. بيٽريون داخل ڪريو، صحيح قطبيت (+ ۽ -) کي ڏسندي.
4. Replace the cover and secure it with the screw(s).

4.2 Connecting Test Probes

Connect the red and black test probes to the appropriate input jacks on the multimeter.

• ڳنڍيو ڪارو test lead to the -COM (عام) جڪ.
• ڳنڍيو ڳاڙهو test lead to the VΩmA+ jack for most voltage, resistance, and current measurements. For high current (10A) measurements, use the dedicated 10A jack if available and specified on the device.

4.3 Mechanical Zero Adjustment

Before taking any measurements, ensure the needle is aligned with the zero mark on the scale. If not, use the mechanical zero adjuster knob (usually a small screw below the dial) to carefully align it.

4.4 Resistance Zero Adjustment

For resistance measurements, after selecting the OHM range, short the red and black test leads together. The needle should move to the zero mark on the OHMS scale. If it does not, use the Ω ADJ knob to adjust it to zero. This must be done for each resistance range selected.

5. آپريٽنگ هدايتون

Always select the appropriate measurement function and range before connecting the test leads to the circuit under test. If the value is unknown, start with the highest range and work downwards.
