INSTRUMENT ERROR WHEN USING ACCESSORY DIAL INDICATOR (WTI-8038S)
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 the
reference position.
③Measuring Height.
Reposition the Dial Indicator Stylus to the surface to be
measured, and adjust the Height Gauge so that the Dial
Indicator reading is 0.00mm.
④The LCD display of the Height Gauge now shows the height
relative to the reference surface.
For this method, the total error is the sum of the Height
Gauge Instrument Error (VHS-30D : ±0.04mm,
VHS-60D : ±0.05mm)＋Dial Indicator repeatability
(0.003mm)
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 the
reference position.
③Measuring Height.
Reposition the Dial Indicator Stylus to the surface to be
measured, and read the LCD display of the Height Gauge.
This value is 10.51mm
④Read the scale of the Dial Indicator.This value is ＋0.10mm
⑤The height relative to the reference surface is the sum, 10.51
＋0.10＝10.61mm
Make sure the sign (＋, −)of the measurement
from the Dial Indicator is same as sign for the
Height Gauge.
For this method, the total error is the sum of the Height
Gauge Instrument Error (VHS-30D: ±0.04mm, VHS-60D:
±0.05mm)＋Dial Indicator Wide Range Error (0.013mm)2. Insert the Scribe to desired overhang and secure by
tightening the Scribe Clamp Screw.
