CARA MENGUKUR RESISTOR DENGAN MULTIMETER ANALOG - Electronics

Introduction

This tutorial provides a step-by-step guide on how to measure a resistor using an analog multimeter. Understanding how to use a multimeter effectively is essential for anyone working with electronics, as it allows for accurate readings of resistance values.

Step 1: Calibrate the Multimeter

Before measuring a resistor, you need to ensure that your multimeter is properly calibrated. Follow these steps to calibrate:

• Turn the multimeter on and set it to the resistance (Ω) mode.
• Connect the probes together to check the meter's response.
• Adjust the calibration knob (if available) until the display reads zero or a very low resistance value.

Tip: Calibration ensures accurate readings, so make this a routine check before every use.

Step 2: Set the Multimeter to Measure Resistance

Once calibrated, set your multimeter to the correct range for measuring resistance:

• Choose the appropriate resistance range based on the expected value of the resistor (e.g., 200Ω, 2kΩ, 20kΩ).
• If you’re unsure of the resistor’s value, start with the highest range and work your way down for more accuracy.

Step 3: Connect the Probes to the Resistor

To measure the resistance of a resistor, connect the multimeter probes:

• Identify the resistor you want to measure.
• Connect the black probe to one end of the resistor.
• Connect the red probe to the other end of the resistor.

Note: It does not matter which probe connects to which end of the resistor.

Step 4: Read the Measurement

After connecting the probes, it’s time to read the measurement:

• Observe the scale on the multimeter.
• Identify the value where the needle points or the digital reading displayed.
• Cross-reference this value with the scale to determine the resistance of the resistor.

Common Pitfall: Make sure to avoid contact with other components while measuring to prevent inaccurate readings.

Step 5: Disconnect and Store the Multimeter

After taking your measurement, follow these steps:

• Disconnect the probes from the resistor.
• Turn off the multimeter to conserve battery life.
• Store the multimeter and probes in a safe place for future use.

Conclusion

Measuring resistance with an analog multimeter is a straightforward process that involves calibration, proper settings, and careful connections. By following these steps, you can ensure accurate measurements every time you work with resistors. As you gain more experience, you can explore other functions of the multimeter to enhance your electronics skills.
