To measure the inside diameter of a ring using a vernier caliper, you must use the small jaw or the internal jaw of a vernier caliper.
Vernier microscope radius of capillary tube
yes,probably we will get accurate measurement.
sources of error in screw gauge
A vernier calliper is used to measure the diameter of a wire so that you can work out its cross-sectional area using the formula for the area of a circle.
using master vacuum gauge and master pressure gauge
The valves on a 1998 Honda Civic EX can be adjusted using a feeler gauge. First remove the valve cover to access the valves. Using a factory service manual look up the proper valve adjustment gauge. Using a special valve socket to tighten and loosen them to the appropriate feeler gauge settings.
Only if you're using more than one feel blade
Valve clearance of Volvo f12, are set using a feeler gauge on the lash adjuster.
Some spark plugs come pre- gaped depending on the vehicle and type of spark plug. But even pre-gaped plugs should be checked with a feeler gauge to be sure it is correct If the plugs you are using are not pre-gaped a feeler gauge must be utilized in order to get an accurate gap reading. Your local auto parts store can help you with what the gap should be for your vehicle.
Use a feeler gauge to set the point gap at .016. .016 inches using a feeler gauge, 50 degrees dwell on a dwell meter using a 4 cylinder scale plus or minus 2 degrees (8 cylinder scale set at 25 degrees plus or minus 2). If the dwell is too high the points are too far closed. A dwell meter is by far the best method, but the feeler gauge is good to get you in the ballpark with new points.
Different manufactures have different specification for spark plug. Check your manual and set it using feeler gauge.
the thickness of a paper match stick is real close.
Stock 350's have hydraulic lifters, so feeler gauges aren't needed. Get yourself a Chilton's manual or similar and read up on the valve adjustment process.
calibrate it .
Calibration of vernier calliper can be done using slip guages i.e. mirror finished rectangular blocks of alloy steel having different sizes & error less than one micrometer. These blocks can be joined together by sliding polished faces over each other to get disired length. Measuring this length & compairing the actual reading, we can calibrate the equipment.
