  • Page 5: Checkout, Calibration And Maintenance

    CHECKOUT, CALIBRATION AND MAINTENANCE gENERAL This book incorporates all motorized “y2Kb/c” balancers manufactured in Conway Arkansas. The test codes for each digital display balancer are alike, and so are the results. The JBC balancer uses “F” to begin any service procedure, the Snapon balancer begins all service procedures with a “P” code. All “F/p” codes run parrallel.
