How do you check hose excentric by dial gauge?

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.
