What should be used to test main rotor leads?

To test main rotor leads effectively, using a multimeter set to ohms is the most appropriate choice. This setting allows for the measurement of resistance across the leads, which is essential for determining the integrity of the rotor winding and connections. By measuring resistance, one can check for continuity and identify any potential issues such as short circuits or open circuits.

In the context of operations involving main rotor leads, it is critical to ensure that resistance values are within specified limits provided by the manufacturer. High resistance or infinite resistance may indicate a break in the circuit, whereas low resistance could suggest a short circuit, both of which can lead to performance issues or failure during operation.

Choosing a different setting on the multimeter, such as voltage measurements, is not suitable for checking resistance directly. Voltage settings are more relevant when assessing live circuits or checking for proper voltage supply but do not provide the necessary information about the condition of the wiring. Similarly, capacitance measurements are not applicable in the context of rotor lead testing, since capacitors are not part of measuring rotor lead integrity. A clamp meter, primarily used for measuring current in a conductor without disconnecting it, would also not provide the resistance measurements necessary for assessing the rotor leads. Thus, utilizing a multimeter set to oh
