This machine shows extremely well. A retired Fellows representative has calibrated it and it is within Fellows tolerances. This machine may be inspected today at our facility. It is located in a climate-controlled, tile floor inspection room - not a warehouse!
These instruments measure and record lead profile variations on internal and external spur and helical gears-with extreme accuracy and reliability. Available as an option is a master lead bar for checking the instrument’s functions. This master carries a modification of known magnitude which, when charted, will show the accuracy of the instrument by repetitively charting the location and amount of the known error.
