1 Holder ore Gauge & Micro Hole Test Interchangeable Rod nvil Nut Dial Indicator (Option) Holder Clamp Screw Grip Joint Guide Contact Point This is designed for measuring diameter of small holes exclusively and can measure diameters from minimum φ.mm to maximum φmm. hen the edge of probe is inserted to a small hole, the edge is closed to inside and presses inner driving rod upward. The principle is that movement is transferred to the extension rod and instructs to dial indicator. Swing width of dial graduation is read as well as bore gauge. It is marked characteristic that stability accuracy indicating performance is high as µm. ore Gauge is the comparative measuring instrument which measures internal diameter of a hole by comparing with master gauge (micrometer, ring gauge etc.). Center of prove and anvil are guided to diameter part of a hole by guide assembly and displacement of contact point is transferred to dial indicator (utomatic centripetal mechanism ) by right angle change in the ratio of : with cam mechanism. Measurement accuracy is changed according to graduation (resolution) of used dial indicator. Measuring range are available from minimum mm to maximum mm according to size of diameter.

6 Technical Data Dial indicator can be installed to bore gauges and Micro-hole Test. It is selectable for easier reading in compliance with objective and dimension range. s to dial indicator installed to bore gauge, dial indicator with flat back is recommended. Lug back is standard for ordinary dial indicators but it will be with flat back by adding suffix "f" to the end of model name. TM- and TM-3C dial indicator is supplied with Flat back as standard.
