Before using an analog volt-ohmmeter to measure resistance readings, what should you do?

Question 1 of 27070

Before using an analog volt-ohmmeter to measure resistance readings, what should you do?

🔍 Key Concepts

• Ohms (resistance) scale on an analog meter and how it is powered • Effect of internal battery voltage on resistance readings • Why and how analog meters are zero-adjusted before taking resistance measurements

💭 Think About

• When you switch an analog meter to an ohms scale, what is actually driving the current through the circuit you are testing? • How can you confirm that the resistance scale on an analog meter is accurate before you connect it to the circuit or component? • Among the choices, which step is normally done every time you measure resistance, not just occasionally?

✅ Before You Answer

• Identify which step directly checks and adjusts the accuracy of the resistance scale before use • Distinguish between routine pre-use procedure vs. maintenance tasks (like battery replacement) • Consider which action uses the meter’s own leads and adjustment control as part of the setup process

Question 1 of 27070

Before using an analog volt-ohmmeter to measure resistance readings, what should you do?

replace all batteries

test the insulation resistance of the leads

make sure the test leads do not touch

hold the leads together and 'zero' the meter
