Indica tor Testers 716, 716M Indica tor Testers 0-1"/0-25MM With direct reading capability to .0001" or 0.002mm, these gages provide a rapid means for calibrating both AGD and dial test indicators for linearity and repeatability through ranges up to 1" or 25mm. This tester design is unlike others because it can be swung to any position between vertical and horizontal by loosening a large hand knob which fastens the gage assembly to the base. In addition, the micrometer head can be turned on its axis and its scale positioned to suit the operator's convenience by loosening a single set screw. Tensioned locking screws prevent tipping of both the gage assembly and the indicator holding clamp during set-up and adjustment. The micrometer head is our 469 super-precision head with reverse reading capability. When testing a 2700 or 2900 Electronic Indicator, a .000050" graduated head is advisable, available on special order. An indicator mounting attachment holds dovetail mount indicators, AGD indicators with 3/8" (9.5mm) stems and indicators with a holder that has a 3/16" (4.7mm) shank. Unit also has a fine adjustment to zero the indicator. 716MX Dial test indicator held in place by an offset attachment Checking AGD dial indicator 716 Indicator Tester (0-1" Range) Cat.
