Frequently asked questions
How do I test a component with this tester?
Remove the component from the circuit when possible, because other parts connected to it can distort the reading. Connect the probes to the component's leads and select the test from the menu or let the tester auto-detect it.
What power source does it need?
It runs from a single 9 V battery, as listed. Use a fresh 9 V battery for stable readings and make sure the battery compartment is closed securely.
