１ Example using dial indicator with measurement

２ Example with measurement read off the Dial

To measure the height from reference surface:①Place the Indicator Stylus on the reference surface, and set
the Indicator to 0.00mm.
②Set the Height Gauge reading to 0.00mm. This is thereference position.
③Measuring Height.
Reposition the Dial Indicator Stylus to the surface to bemeasured, and adjust the Height Gauge so that the DialIndicator reading is 0.00mm.
④The LCD display of the Height Gauge now shows the height
relative to the reference surface.

To measure the height from reference surface:①Place the Indicator Stylus on the reference surface, and set
the Indicator to 0.00mm.
②Set the Height Gauge reading to 0.00mm. This is thereference position.
③Measuring Height.
Reposition the Dial Indicator Stylus to the surface to bemeasured, and read the LCD display of the Height Gauge.
This value is 10.51mm④Read the scale of the Dial Indicator. This value is ＋0.10mm⑤The height relative to the reference surface is the sum, 10.51＋0.10＝10.61mm
