The Basics Part 1-3: Peak and Null
Understanding how a locating receiver works is also a critical component to locator training. There are several key components on any given receiver that require significant attention, and not all receivers are the same.
Of course, there are some universal elements that can be understood about every modern receiver. Two of those elements are peak and null. Peak usually refers to a number unit on the receiver (Figure 7), while null (Figure 8) usually refers to directional information. Whether you know locating or you’re just now learning locating, it’s important to recognize that arrows are guidance. They show you which way to move the receiver as it is swung laterally over the direction of the conductor.
