1.0 INT ODUCTION
odels TG and TG-DX benchtop contact thickness gauges accurately and
conveniently perform geometric dimensional testing (thickness measurement) on
rubber, fabrics, foams, tapes/films and a wide assortment of other soft materials.
They employs specified presser foot (feeler) of a specific diameter/area, combined
with a predetermined mass (weight) as noted in the AST D 3767 standard.
The TG odel is supplied with a unique air damping feature which ensures that
the presser foot descends at the same rate for each test. This eliminates human
error resulting in superior repeatability. If required, the rate of descent can be user-
adjusted.
For those requiring data output for recording and quality documentation
purposes, a serial output cable and Windows-based software program is
optionally available.
The TG-DX model is supplied without the air dampener option.

2.0 UNPACKING AND SET-UP
Your TG system is packaged completely assembled and tested at our plant to en-
sure a quality product. However, there are some basic steps that must be
performed before using your TG for the first time.
1. Carefully unpack the TG or TG-DX. Take special care when lifting to
support the unit from the granite base when unpacking and
whenever moving the unit.
2. If additional presser feet and weights (mass) have been ordered be
sure to also unpack those items, which are wrapped separately.
3. After the unit is unpacked, it can be cleaned with alcohol,
WITH EXCEPTION OF THE ELECTRONIC INDICATOR.
4. The TG or TG-DX should then be placed on a clean, flat vibration-free
surface for use.
3.0 INSTALLING BATTE IES
1. Using a narrow edge, flathead screwdriver, gently pry
under the tab on the left side of the indicator bezel and
slide out the battery tray as you turn the indicator face
down.
2. Insert two CR 2450 Lithium batteries (3V) into the
tray cavities, positive (+) side up. Now slide the tray
back into its slot, taking care that the batteries stay in
proper position.

5.0 USING THE INDICATO FUNCTION KEYS
To turn the indi ator ON.
1. Press and hold the ON/ lr key
until lr appears on the indicator
display, then release.
To turn the indi ator OFF.
1. Press and release the OFF/MODE key.
To lear the indi ator display to zero.
1. Press and release ON/ lr key
until .0000 appears on the display.
To turn MAX HOLD on and off.
1. Press and release the HOLD key. MAX will appear on the screen
when this function is active. Repeat to turn this function off.
To hange the indi ator units from in h to millimeter or millimeter to in h.
1. Press the IN/MM Key. Each time the key
is pressed the units will toggle between
Inch (IN) and .
2. The units indicator will be shown on the
right side of the display
To turn AUTO OFF on and off
1. Press and hold 2ND key.
2ND appears at the top of display,
2. Press and release the OFF/MODE
key within three seconds to activate
your selection. An hourglass will
appear on the left side of the display
when the AUTO OFF feature is active
NOTE: AUTO OFF is activated after 10 minutes of non-use.

To Clear All Settings And Return To Fa tory Set Defaults:
1. Press the 2ND key.
2ND icon will appear at the top of the display.
2. Press the ON/ lr.
3. Press and release the IN/MM key.

6.0 OPE ATING POCEDU ES
The TG system can be used to check the thickness of rubber and rubber type
materials.
Note: The TG System is supplied with a 16mm diameter presser foot
and 212 gram mass. This configuration is commonly used for measurement 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, textiles, felts,
sheet metal, foils, fabrics, cloth, leather, fiberboard,
plywood, paper, etc.
1. Use the Adjustment Knob (1)
to position the Indicator so that the
the presser foot is resting freely on
granite base.
2. Clear indicator display to zero by
pressing and releasing the ON/ lr
key.
3. Use the Lifting Lever (2) mechanism
to raise the presser foot.
4. Place the material to be tested
under the Presser Foot (3) and
release the lifting lever.
Note: odel TG is supplied with a unique air-damping feature that controls the
rate of decent of the presser foot (not supplied with odel TG-DX). 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.

6.1 Checking Thick Materials
For checking materials over 1 inch in thickness, use precision ground gage
blocks in conjunction with the TG.
Example: If you are checking a 2 inch thick part you can use a
1 inch gage block positioned under the sample to obtain the
thickness values.
The maximum sample height capacity of the TG is 5 inches.
6.2 Data Port
For those requiring data output for recording
and quality documentation purposes, a serial
output cable and Windows-based software
program is optionally available.
NOTE: For complete detailed instructions on operation of the Electronic
Indicator, refer to separate Indicator anual supplied or download
