How do you use a telescopic bore gauge?

Place the top of the telescopic gauge inside the bore at the exact position you wish to measure. Then slowly twist the locking screw anticlockwise until the telescopic rods come out of their casing. Continue twisting the locking screw until the ends of the telescopic rod touch the sides of the bore.

Simply so, what does a telescopic gauge do?

Telescopic gauges are used to measure the internal diameter of a bore, hole or groove up to 150mm (6″) in diameter, for example camshaft bearings or connecting rod bore bearings. They are primarily used by mechanics measuring the bore size of a crankcase in an engine where the pistons move up and down.

Additionally, how do you calibrate a bore gauge? A micrometer can be used to calibrate the bore gauge. Set the micrometer to the desired size and lock. Insert the measuring head between the micrometer. A setting ring can be used to calibrate the bore gauge.

Likewise, how accurate is a telescopic gauge?

When using a micrometer to set a dial bore gauge, the accuracy of the measurement will be 0.002 inches or 0.0508 millimeters. When a dial bore gauge is set using a ring gauge, overall accuracy can be within 0.0001 inches or 0.00254 millimeter.

What is a depth gauge called?

A depth gauge is a pressure gauge that displays the equivalent depth in water. It is a piece of diving equipment used by underwater divers, submarines and submersibles. A depth gauge that measures the pressure of air bubbling out of an open ended hose to the diver is called a pneumofathometer.
