ABSTRACT:
Bourdon tubes should be exercised prior to each calibration by causing the ube to move repeatedly through its normal coiling and uncoiling arcs amounts sufficient to produce full scale deflection of the gage pointer. The exercising movements conventionally have been accomplished by applying pressure inside the tube. It has been found that these exercising movements can be accomplished with equal reliability and considerably less expense by engaging the tube end with a pivoted lever and by using a control screw for pivoting the lever.
