Before connecting cartridge terminals to the electrical system of a fire extinguisher, what should be checked?

Check with an ammeter for current flow.
Check with a voltmeter to see that no voltage exists at the terminal connections.
Check the resistance across the terminals with an ohmmeter.
Ensure the terminals are properly lubricated.

The correct answer is: Check with a voltmeter to see that no voltage exists at the terminal connections.

Before connecting cartridge terminals to the electrical system of a fire extinguisher, it is important to check that no voltage exists at the terminal connections using a voltmeter. This eliminates the risk of electric shock and ensures the safety of the person handling the terminals. Checking with an ammeter for current flow or using an ohmmeter to check the resistance across the terminals are not necessary since the terminals should not have any voltage present. Ensuring the terminals are properly lubricated is also not relevant in this situation and will not affect the integrity of the connection.
