🔍 Key Concepts

• Ohmmeter operation and how it uses an internal battery to push current through a circuit • What happens if you leave a sensitive measuring device (like a pyrometer indicator) connected while another meter sends current through it • Difference between continuity testing (circuit wiring only) vs. testing the instrument itself

💭 Think About

• When an ohmmeter is on the resistance/continuity setting, what is actually flowing in the test leads, and where is it coming from? • Is the pyrometer indicator designed to be powered by the ohmmeter’s internal source, or by its own normal circuit? What could that imply? • When troubleshooting wiring, what parts of the circuit do you actually need connected to get a valid continuity reading?

✅ Before You Answer

• Identify that an ohmmeter contains its own battery and applies a small voltage/current to the circuit under test • Decide whether the pyrometer movement/electronics are intended to see that meter battery voltage/current • Confirm that for continuity tests of wiring, the instrument being measured is usually isolated/removed to avoid damage or false readings

Question 1 of 20

Prior to testing the pyrometer circuit wiring for continuity with a multimeter, you should disconnect the pyrometer because __________.

the driving voltage of the meter batteries can damage the circuit meter

the pyrometer total resistance can damage the ohmmeter

the reactance of the pyrometer will give a false meter reading

meter current running through the pyrometer will permanently magnetize the pyrometer's pointer
