6.0 O PERATING P ROCEDURES
The MTG system can be used to check the thickness of rubber and
rubber type materials.
Note: The MTG System is supplied with a 16mm diameter presser foot
and 212 gram mass. This configuration is commonly used for measure-
ment of all rubber materials with a hardness of 35 IRHD or below
Optional presser feet and mass combinations are available to check
a wide assortment of other material such as: foams, tapes, films, tex-
tiles, felts, sheet metal, foils, fabrics, cloth, leather, fiberboard,
plywood, paper, etc.
1. Use the Adjustment Knob to
position the Indicator so that the
presser foot is resting freely on the
granite base.
2. Clear indicator display to zero by
pressing and releasing the ON/clr
key.
3. Use the Lifting Lever mechanism
to raise the presser foot.
4. Place the material to be tested
under the Presser Foot and
release the lifting lever.
Note: Your MTG system is supplied with a unique air-damping feature
that controls the rate of decent of the presser foot. This allows the
presser foot to descend at the same rate for each test, thus eliminating
human error resulting in superior repeatability.
5. If required, the rate of descent can be user-adjusted by carefully
turning the knurled knob located at the top of the air dampener
(turn clockwise to slow the rate, counter-clockwise to speed up
the rate). Care should be taken to not over adjust the dampener
by over-rotating the adjustment knob.
6. Read and record the thickness of the material immediately after
the presser foot makes full contact with the material.
Note: The pressure being applied by the instrument has a significant
effect on the results obtained. The weight (mass) and presser foot
diameter should be specified.
