How to Read/Use a Direct Reading-Lenker Style Grade Rod

The Lenker-Style Grade Rod uses a system that eliminates the need for math and the risk of miscalculations on the job site. It uses a laser receiver, which can be used to read the grade of the ground. And it has a tape face that be set to either the benchmark elevation or one that is desired. The elevation is determined by reading the last three numbers of the elevation, which is measured to the nearest hundredth. And by moving the laser receiver until you hear a solid tone, you can get accurate measurements quickly without the need for math or complex calculations. The Lenker Rod is a method that has been around for a long time, and it’s still a great way to measure elevation grade on a job site.
