A dial gauge, or dial indicator, is a precision tool used to measure distance. It is used in industrial and automotive workshops. Many types of distances can be measured with a dial gauge. For example, the depth of a hole can be measured; the distance between the top of a motor piston to the deck of the engine block called — — deck height can also be determined. A brake rotor can be checked for exhaustion, or how flat and even its surface is. Dial comparators use several types of media, one of which is the magnetic base. This support allows the user to mount the gauge on a ferrous metal surface.
Instructions
• Place the magnetic base on the metal surface where you want to use the comparator. Note, the magnetic base does not adhere to stainless steel, aluminum or non-ferrous metal.
• Turn the knob on the base to activate the magnet. It will “stick” to the surface of the metal.
• Screw a mounting arm into the upper part of the magnetic base. The arm is a threaded rod at one end. A magnetic base must have two arms — one that screws into the base and another that can be attached to the base arm with a clamp that allows the second arm to slide up and down on the base arm. The clamp also allows the second arm to slide along the clamp.
• Mount the dial gauge on the mounting arm you are going to use. This is a mounting hole on the back of the gauge that attaches to a mounting flange. The clamp has a threaded stud that fits over it in the hole at the back of the dipstick. A threaded knob holds the gauge on the stud. The clamp slides on the mounting arm and is held in place by a set screw.
Tips and Warnings
- Your magnetic base should have two arms. Threaded at one end, and threaded. Clamping device that accepts both arms, and dial gauge pliers that slide on each arm as needed.
