The MRP includes three models, which gives the gage its versatility. The different framesizes allow each MRP model to measure a specific range of diameters. The MRP 1000 handlesdiameters from 1 ½” to 4 ½”, the MRP 2000 fits diameters in the 2⅜” to 13⅜” range and the MRP 3000tackles the 8⅝” to 20” diameter range.The tubular rail and block construction allows the MRP gage to set securely on the face of theconnector without any special adjustment. The gage uses two pivoting shoes that rest on the crests ofthe threads during inspection. Any variations in pitch diameter detected during inspection are shown onthe gage’s indicator.Before inspecting parts, the MRP gages must be preset to a nominal predetermined dimension. Fordetermining the gage’s setting dimensions and gauging tolerances, this manual includes tabled settingvalues as well as formulas for calculating setting dimensions. The MRP gages can be preset using Rodor Frame Style setting standards or Gagemaker’s MIC TRAC MIC TRAC measurement center.To inspect parts, the pivot shoes are placed on the crest of the threads of the part and the gage isproperly positioned by sweeping to obtain the largest indicator reading. It is also recommended that thegage be zeroed periodically during use to maintain accurate readings.Technical SupportPhone: 713-472-7360Hours: Monday – Friday 8AM – 5PM (CST)Product Information and UpdatesVisit our web site at: www.gagemaker.com4
