Using vernier caliper to measure inside surface measurements

To measure the distance between inside surface , or the inside diameter of a hole, with a vernier caliper, use the sale marked �in-side� Remember that if you are using a vernier caliper with both metric and English scales , the scales appear on opposite sides of the caliper and apply only to outside measurements. Then , to get correct inside measurements , you add to the actual reading the measuring point allowance for the size of caliper you are using. Take this allowance from table or the manufacturer’s instructions . The actual measurement in this case is made in the same manner as taking an outside measurement.
