How to read a manual vernier caliper

Basically, the thumb rule in reading vernier caliper is similar both for the inch and mm scale. Final Result = Main Scale Reading + Vernier Scale Reading – Zero Error. The main scale reading is the amount of the vernier scale divisions that are completely passed by the vernier scale’s zero line.  · Measurement without zero error: –(–) = – (– ) = cm. If you do not understand the subtraction of the negative zero error from the measurement, please read on. Since the zero error is cm, this means that all measurements taken by the vernier calipers will be SMALLER by cm. you remove the caliper from the workpiece, press the button to zero the caliper while it is set to the thickness of the workpiece. Now use the depth blade to measure the depth of the hole. The caliper reading (shown as a negative number) is the remaining thickness between the bottom of the hole and the other side of the workpiece.

The main scale on a Vernier caliper typically tells you the whole number plus the first decimal. Read this just as you would a ruler, measuring to the zero mark on the sliding (Vernier) scale. For example, if the 0 on the sliding scale lines up with the 2 inch mark, your measurement is 2 inches. A is the line of the main scale which is on the left of the zero line of the vernier scale. B is the line of the vernier scale which coincides with a line of the main scale. C is the reading 2. Measurement: 3. Clamping Screw: Tighten the screw to lock the reading when you have to remove the caliper before reading. 4. Fine Adjustment. Instructions on how to read Vernier caliper mm and mm resolution.
