Measuring Equipment Frequently Asked Questions:


What are some common features to look for when choosing a tape measure?
It sounds obvious enough, but length is a primary consideration. Too short limits the tape measure’s uses. Too long needlessly adds extra weight to your toolbox. The measurement scale (feet and inches vs. meters and centimeters) and clarity of its markings is also important. Other considerations include the hook type, construction (steel, fiberglass or stainless steel), case type and automatic vs. manual locking mechanism.
Can measuring wheels be used on uneven surfaces or slopes?
Measuring wheels can be used on uneven or sloped surfaces. However, larger diameter measuring wheels are recommended to improve the accuracy on uneven surfaces.
How do you calibrate a measuring wheel to ensure accurate measurements?
The specific procedure may vary from one measuring wheel to another. Check your owner’s manual for detailed instructions.
What is a grade rod and how is it used?
A grade rod is a graduated rod for reading elevation changes on jobsites. Grade rods can be used with surveyor, optical and laser levels.
How do you read a grade rod and what are some common mistakes to avoid?
Extend the grade rod, set up the transit level. Determine points. Hold the grade rod vertically. Make note of the measurements on the grade rod. Not having the rod fully extended and reading errors are a couple of the common mistakes.
