Takeaways

🔧 Connect the multimeter probes correctly as per the tutorial's instructions.
🔄 Set the digital multimeter's rotary switch to the 200 ohms range, which is the minimum setting.
📏 Touch the probes to any side of the resistor to measure the resistance.
❌ If no resistance value shows, it indicates the resistor has a higher resistance than the current range.
⚙️ Rotate the multimeter switch to a higher range (kilo-ohms) to recheck the resistor.
📉 The multimeter displayed a reading of 0.993 ohms, meaning the resistor's resistance is close to 1 kilo-ohm.
🔍 If a second resistor shows no reading, increase the range and test again.
⬆️ Continue increasing the range if the multimeter still shows no reading for higher resistance values.
🧮 When set to 200 kilo-ohms, the multimeter displayed a resistance of 178 kilo-ohms.
👍 This tutorial explains how to measure resistance using a multimeter, with steps for increasing the range when necessary.

Q & A

What is the first step to measure resistance using a digital multimeter?
-The first step is to connect both probes according to the tutorial instructions.
Which setting should the multimeter be on to measure low resistance?
-The digital multimeter should be set to the 200 ohms range, which is the minimum range of the multimeter.
What should you do if the multimeter doesn't show any resistance value?
-If the multimeter doesn't show any resistance value, it means the resistor has a higher resistance, so you should rotate the rotary switch to a higher range, such as kilo-ohms, and check again.
What does a reading of 0.993 ohms indicate about the resistor?
-A reading of 0.993 ohms means the resistor has approximately 1 kilo-ohm of resistance.
What should you do if the multimeter still doesn't show any reading after increasing the range?
-If there is still no reading, continue to increase the resistance range and check the reading again.
What was the resistance of the second resistor in the tutorial?
-The second resistor showed a resistance of 178 kilo-ohms.
What does it mean if the multimeter doesn’t show any reading when testing a resistor?
-It means the resistance of the resistor might be higher than the current range set on the multimeter, so you should increase the resistance range.
Why is it important to increase the resistance range on the multimeter when testing resistors?
-Increasing the resistance range allows the multimeter to measure higher resistances that may exceed the capacity of lower ranges.
Can you touch the probes to either side of the resistor during the measurement?
-Yes, you can touch the probes to either side of the resistor as it doesn't matter which side is connected to which probe.
