GENERAL DESCRIPTION
The MIG (Manual IG Thickness Gauge) is a durable tool used to measure glass and
glass are used to determine the thickness of glass, as well as the air space separating
the pieces of glass in a sealed IG assembly. The readings are taken from a single side
of the IG unit and no additional tools are necessary.
Durable scales are interchangeable on the sliding assembly. The multiple scales are
held in place by two black, nylon thumb screws. Due to the scales thin size, the opera-
tor can carry numerous scales inside the carrying case and always be prepared for any
(mm) on one side, and Imperial (inches) on the back side.
The operator can easily measure glass thickness, air space, overall IG thickness, indi-
vidual panes of glass in a laminated assembly, bullet resistant and triple pane assem-
blies. The gauge also has been successfully tested for measuring thickness of mirrors
and other transparent materials.
The MIG is powered by two standard AAA alkaline batteries (included). Two (2) spare
thumb screws are included with each gauge. The black nylon carrying case supplied
with the gauge provides a handy method for carriage.
ZERO ALIGNMENT
The two thumb screws are used to position the scales correctly on the slide assembly.
For ease of use, when the slide is pushed completely in (against the stop), the scales
assembly to make sure it is free of dirt and debris.
To align the scale, push the slide assembly completely in (against the stop). Place the
gradient. DO NOT move the entire slide assembly, only the scale itself. Once you have
positioned the scale to your satisfaction, tighten the thumb screw in the lower right cor-
ner. After tightening this screw, verify that the zero point is still aligned. If not, readjust
are centered on the viewing area. Also, before tightening the upper left screw, apply
the slide assembly.
Each time you switch to a new scale, it will be necessary to realign the “zero point”. The
additional scales for the gauge are included in the carry case.

taking glass thickness readings. All new units are shipped from the factory with the
zero point already aligned. If the zero point is out of alignment or if the operator is
changing scales, follow the instructions under “Zero Alignment”.
3. Power Switch: Prior to energizing the laser, be aware of your surroundings. The laser
will exit the gauge from the back side. DO NOT LOOK DIRECTLY INTO THE LASER
BEAM AND NEVER POINT THE LASER BEAM IN THE DIRECTION OF ANOTHER
PERSON. To turn on the laser, simply push and hold down the power button. The
laser will activate instantly.
4. Slide Assembly: The slide assembly holds the calibrated scale in place and allows
the operator to move the zero point left and right while taking readings. While taking
readings, the slide assembly starts in the fully inserted (against the stop) position.
measure the air space and subsequent lites of glass.
5. Thumb Screws: The thumb screws are used to align the scale with the zero point as
well as to hold the scale in place. The thumb screws also provide a handy method of
grasping the slide in order to move it left and right. Two (2) spare thumb screws are
included in the carry case.

the acceptable tolerances in the various glass thickness ranges. A table is printed on
page 3 of this operating manual for your reference. The four lines on the scale repre-
sent the thickness ranges of the four most common glass thicknesses used in North
America: 3/32”(SS), 1/8”(DS), 3/16”, and 1/4”. These designations are represented
on the scale respectively from right to left, as illustrated below. As you become more
-
ations and look directly at the ASTM range designations to expedite the measuring
process. PLEASE NOTE, the actual glass thickness you measure, can be less than
the traditional designations used by the ASTM standard range. For example, notice
that traditional 1/4” glass is actually closer to 7/32” in thickness.
