INSTRUCTIONS FOR USE
A. NON – TRANSPARENT MATERIALS
USE 10X OBJECTIVE LENS AND 10X RETICLE EYEPIECE.
NOTE: 10X OBJECTIVE LENS FOCUSES APPROX. 0.250"
ABOVE THE TARGET.
DEPTH MEASUREMENT
1.
Set the height of the OBJECTIVE LENS at approx. 0.250" over
the target.
2.
Shine the FLASHLIGHT down through the top of the EYEPIECE.
A small light "spot" will appear beneath the OBJECTIVE lens, use
this to locate or "spot" the target.
3.
Insert the FLASHLIGHT into base.
4.
Look through EYEPIECE and focus and position over target.
5.
Hold the base of the micrometer for support while focusing to
prevent it from moving.
6.
Bring undamaged surface near scratch (surfaceA in diagram on
next page) into sharp focus, and press the "ON/ZERO" button
(display should now read "0.0000").
7.
Focus into bottom of scratch (surface B in diagram on next page),
without moving micrometer. DEPTH is shown on digital display.
8.
Repeat steps 5.-6 for verification and record results.
WIDTH MEASUREMENT – 10X RETICLE EYEPIECE
USE 10X RETICLE EYEPIECE AND 10X OBJECTIVE LENS
ONLY.
DO NOT USE 4X OBJECTIVE LENS WITH RETICLE EYEPIECE
TO MEASURE WIDTH, READINGS WILL BE INACCURATE.
Depth and thickness measurements are fine with this combination.
1.
Locate target per steps 1. – 4. above.
2.
Focus on target.
3.
Rotate EYEPIECE to align scale with target.
4.
Observe and record width.
WIDTH RANGE: 0.000"-0.040" (0.00-1.00mm),
increments of 0.001" (0.010"mm).

INSTRUCTIONS FOR USE
B. TRANSPARENT MATERIALS
USE 4X OBJECTIVE LENS and 10X RETICLE EYEPIECE.
NOTE: 4X OBJECTIVE LENS FOCUSES APPROX. 1.30" OVER
THE TARGET.
THICKNESS MEASURMENT
1.
Focus on nearside, set display to 0.0000"
2.
Focus on far side and record depth.
3.
Multiply result by 1.5 (index of refraction for most
transparencies. Check index of subject material).
RANGE: UP TO APPROX. 1.8" THICK TRANSPARENCY.
