Tool Recognition and Use Flashcards

Which tool is used to measure the resistance of an elevator motor winding?

Answer: Ohmmeter or multimeter in resistance mode

An ohmmeter (or multimeter set to resistance) measures winding resistance in ohms to check for opens or shorts.

A technician is testing insulation integrity of elevator motor windings. Which specialized instrument is required?

Answer: Megohmmeter (megger)

A megohmmeter applies high voltage to measure insulation resistance in megohms, revealing degraded insulation.

When cutting the threads on a threaded rod used for hitch plate installation, which tool is used?

Answer: Die and die stock

A die and die stock cuts external threads onto a rod; a tap cuts internal threads inside a hole.

Which tool is used to cut a clean hole through a steel panel for a push button or indicator fixture?

Answer: Hole saw or chassis punch

A chassis (knockout) punch or hole saw produces a clean, correctly sized hole in a steel panel for electrical fixtures.

What tool measures the actual running current of an elevator motor without interrupting the circuit?

Answer: Clamp ammeter (clamp meter)

A clamp ammeter slips around a conductor and measures current via electromagnetic induction without breaking the circuit.

Which tool is used by an elevator mechanic to crimp a compression terminal onto a heavy copper conductor?

Answer: Hydraulic crimping tool

A hydraulic crimping tool applies the high force needed to make a gas-tight crimp on large copper terminal lugs.

A damaged safety switch housing bolt must be drilled out. After drilling, which tool restores the original threads?

Answer: Tap

A tap cuts internal threads into a drilled hole to restore the original thread profile.
