૬.૨ કનેક્ટિંગ ટેસ્ટ લીડ્સ

The multimeter comes with two test leads, typically one red (positive) and one black (negative/common). Proper connection is crucial for accurate and safe measurements.

1. For most voltage, resistance, and low current measurements, connect the black lead to the 'COM' (Common) jack.
2. Connect the red lead to the 'V-Ω-mA' jack for voltage, resistance, and milliampere current measurements.
3. ઉચ્ચ પ્રવાહ માપન (10A સુધી) માટે, લાલ લીડને '10A' જેક સાથે જોડો. Always ensure the correct jack is used to prevent damage to the meter or circuit.
