How To Read A Vernier Gauge. The vernier reading is found by locating the best aligned lines between the two scales. How to read vernier caliper’s zero error;
Are the jaws of the caliper for meas… To read a vernier caliper: First we have to find out what is least count of vernier depth gauge, in this case we have least count of 0.10 mm.
How to read the scale graduation : How to read a vernier (caliper): The main scale reading is that to the left of the zero on the vernier scale.
The major tests on vernier height gauge are straightness, squareness, the parallelism of the working faces of the beam, measuring jaw and scriber and the accuracy of the scale readings are done by following methods. The hardness of working faces. The vernier reading is found by locating the best aligned lines between the two scales.
To read a vernier caliper: Just look for the line on the vernier scale which is perfectly aligned with mark on the main scale. Add the result of the main scale and (vernier scale x accuracy of vernier scale) to get the reading of the micrometer screw gauge.
This requires reading a vernier height gage scale: For example, the numbers on a vernier scale represent 0. The reading is therefore 3.7 mm.
Hence, the vernier scale reading is 0.03 cm. It reads 3.58 ± 0.02 mm by adding 3.00 mm (left red mark) on the fixed main scale to vernier 0.58 mm (right red mark). Multiplying the bottom scaling line of the vernier scale read is 10 scale x 0.05 mm resolution equals 0.50 mm.
