Inquiry (采购产品): Almen Gage Indycator Dear Sir, We have an almen gage which includes mahr federal indicator. The indicator model no is EDI 10402 and serial number is 2258. We would like to make the calibration of the indicator according to user's manual but we could not. We followed the instructions written in the users manual, section 5.6 calibration mode. According to user's manual M3 (calibration screen) should be appear after performing the steps 1 through 7, but after pressing M/OFF two seconds the M3 does not display. What should I do to enter the calibration mode. **** Hidden Message ***** Serkan Kaptan 26320 Company: 1nci HIBM E-mail: skaptan@hvkk.tsk.tr **** Hidden Message ***** skaptan@hvkk.tsk.tr
