What is the primary method used for measuring voltage and current in propeller anti-ice testing?

The primary method used for measuring voltage and current in propeller anti-ice testing is the voltmeter/ammeter draw measurement. This method allows technicians to accurately assess the electrical load being drawn by the anti-ice system during operation.

In propeller anti-ice testing, it is essential to verify that the system is functioning correctly and that the electrical parameters fall within specified limits. The voltmeter measures the voltage across the anti-ice system, while the ammeter measures the current flowing through it. By assessing both voltage and current draw, technicians can determine the operational health of the system and whether it is performing as designed.

Using a voltmeter/ammeter setup provides a direct measurement of electrical parameters, which is crucial for ensuring safety and efficacy in anti-ice operations. Other methods, while they may provide useful information in different contexts, do not offer the same precise measurements necessary for this specific application.
