almost the problem in the dial gage
A round gauge with a needle to point at the measure.
To calculate the deflection of a dial gauge with a least count of 0.01mm, you read the measurement indicated by the needle on the dial gauge after it has been set to the initial position. The deflection is the difference between the initial reading and the final reading on the dial gauge. Deflection = Final reading - Initial reading.
first fix the dial gauge at a zero settling level than place the object to be measured below it then move it to touch the thing when it touches mark the reading whether its +vwe or -ve then length equal to =original length+dial gauge reading *least count
by measuring its diameter
Dial gauge.
feeler gauge
today i observed errors between puppy dial reading & height gauge dial reading. this was 10μ to 20μ when we go to .1 mm
To check hose eccentricity using a dial gauge, first secure the hose in a stable position and ensure it is free from any bends or kinks. Place the dial gauge on a fixed point adjacent to the hose and slowly rotate the hose while observing the gauge's reading. The gauge will indicate variations in diameter, with deviations from a consistent reading signaling eccentricity. Record the maximum and minimum readings to assess the extent of the eccentricity.
They have a spring attached to a dial or needle pointing at the weight on a gauge. Both spring and gauge are highly calibrated.
By the use of feeler gauge and with dial indicator as possible.
It is a measuring gauge use to measure length and with
