Cathodic Protection Tester Practice Exam

Which of the following is true about the digital meters used in cathodic protection testing?

1. They only measure current

2. They are outdated technology

3. They require manual readings

4. They provide a digital display of measurements

The correct answer is: They provide a digital display of measurements

Digital meters used in cathodic protection testing indeed provide a digital display of measurements. This feature allows users to obtain precise readings of various parameters, such as voltage, current, and resistance, in a clear, easy-to-read format. The advantages of digital displays include enhanced accuracy, greater ease of interpretation, and the ability to log data for analysis over time. This capability is especially crucial in cathodic protection systems, where accurate monitoring helps ensure that corrosion prevention measures are effectively implemented. Digital meters often include features like auto-ranging and memory functions, which further enhance their usability and efficiency in field applications, making them a valuable tool for professionals in the industry.
