For the screw gauge shown below, the least count is 0.01 mm. What is the zero error?
– 0.95 mm
+ 0.95 mm
– 0.05 mm
+ 0.05 mm
As the zero of the head scale lies above the pitch scale axis, the zero error is negative.
Zero Error = – (100 – 5) × L.C = – 95 × 0.01 mm = – 0.95 mm
For the screw gauge shown below, the least count is 0.01 mm. What is the zero correction?
A screw gauge, when closed without anything in between it, shows reading as shown below. Determine the zero correction for it if the least count of the screw gauge is 0.01 mm.
It is found that for a screw gauge, the 5th division of the head scale coincides with the pitch scale axis and the zero of the head scale lie below the pitch scale axis. The least count of the screw gauge is 0.01 mm. What is the zero correction?
