49-87
0-0.500 in (Imperial Units)
0-12.7 mm (SI Units)
The TMI Digital Micrometers – 49-8X Series combines a precision thickness measuring system with a
digital readout. The motor-driven instrument utilizes the dead weight micrometer principle. Each unit
has been designed and manufactured for use where the utmost precision is required, completely free of
operator influence.
The instrument consists of a heavy, solid frame which supports the unit and houses the thickness
measurement transducer and associated circuitry. A digital readout is provided to automatically
display the actual specimen thickness. The lower anvil as well as a movable pressure foot is made from
lapped, stainless steel.
APPLICATION
The TMI Micrometer is designed to measure the thickness or caliper of paper sheets, films and foils.
Almost any material including paper, natural or synthetic fabrics, leathers, metals, plastics and rubber
thickness can be measured with precision and accuracy. The 49-86 and 49-87 models also feature an
on board statistics package that stores up to 100 readings, calculates and displays the average, standard
deviation, maximum and minimum of the readings that are stored in the instrument’s temporary
memory.

SETUP
1. Take the micrometer out of the box and place it on a rigid, level bench top, free from large
temperature variations, excessive air currents and vibration. Ensure there is appropriate clearance
from the rear of the instrument to easily operate the power shutoff device.
2. MAKE SURE TO REMOVE THE SHIPPING COLLAR FROM THE ANVIL SPINDLE.
(The Shipping collar is typically a plastic tube secured by a large cable tie).
3. If included, mount the Split Weight to the micrometer spindle using the included 9/64” Allen
Wrench. (Split Weights are removed for shipping)
Note:
Please handle the split weights with great care to avoid damage. The edges of the split weights can
have sharp edges. Please be aware of the possible danger of cutting yourself!
4. Remove the rubber pad that is located in between the anvils during shipment.
(If the machine has a range of 0.000”-0.050” you will have to gently lift upper anvil enough
to slide the pad out).
5. Connect the power cord from the power entry module (located on the back of the unit) to a
suitable AC outlet, free from electrical noise and large voltage variations.
Warning:
If the supplied power plug needs to be adapted to the local power requirements this must be done by a
qualified electrical engineer. The plug must be equipped with a safety earth terminal.
Please Note:
Power cord wire colors:
Brown or Black = Line
Blue or White = Neutral
Yel/Grn or Green = Earth/Ground
OPERATION
1. Ensure that the shipping collar has been removed from the unit. Serious damage can occur if
the shipping collar has not been removed.
2. Turn the power switch to the “On” position. At this time, the display and start/stop button will
become illuminated. The first screen will only show until the end user confirms that they have
removed the restraints. TMI is not liable for damage cause by disregarding this warning.
3. The second screen will now appear. The machine will need to run 2 to 3 cycle to find the limits of
its travel. This is done by pressing the Units button. While cycling, the blue LED button should
pulse.
4. The third screen will remind you to clean the anvils for optimal performance. Draw a piece of
soft-body paper through the pressure foot and anvil; this will remove any foreign matter. Also
visually inspect the anvil surfaces for any debris, it might be necessary to use a small amount of
rubbing alcohol to clean them.

5. The fourth screen to appear will be the main testing screen. It displays the measured gap, the
units, and the time. For best results, allow the micrometer to warm up for approximately 30
minutes minimum before performing any tests. It is highly recommended to always zero the
instrument before running samples.
6. Zero the Micrometer: To zero the micrometer, press the Zero button on the front panel.
Pressing this will tell the machine to zero itself the next time that it comes to rest on the lower
platen or other static object.
7. If you wish, you can perform a quick check of your micrometer. This is done with the TMI Gauge
Blocks:
For Model 49-85 and 49-86:
TMI # 35-12-02
For Model 49-87:
TMI # 35-12-03
Slip one of the gauge blocks between the pressure foot and the anvil. Ensure that the gauge block
is located at the visual center of the anvils. The digital display reading should be the same as the
thickness of the gauge block. (See the instrument’s calibration record for tolerance.) If the
micrometer does not give the correct reading of the gauge block, calibrate the micrometer. (See
Section 9 – Calibration of the micrometer.)
8. All samples that are to be tested should be prepared and conditioned according to TAPPI T400 or
applicable standards. Each sample should be cut and prepared as described in TAPPI T411 or any
other applicable standard. Any samples that are kinked, bent or creased should not be used since
this may affect the reading of the sample.
9. Measure the thickness by placing the specimen between the automatically cycling pressure foot
and the anvil when they are apart. Ensure that the specimen fully covers the area of contact
between the pressure foot and the anvil. During the time when the pressure foot rests on the
specimen, the specimen's thickness is measured and displayed on the digital readout. At the end
of the cycle time, the pressure foot again moves upward and a new measurement can be made. Be
sure to only take one reading at one point on the specimen.
Special Notes on Operation:
- Readings that appear to be slightly out of tolerance have a high likelihood of being caused by
trace amounts of debris left on the surfaces of the anvils.
USER OPTIONS MENU (49-86 and 49-87 only)
You may enter the User Options Menu from the main screen by pressing and holding the Units
Button and pressing the Zero Button. This menu contains the following options:
Password Protection (optional)
The instrument’s Options Menu can be protected by a “manager” password if the user chooses to
do so. The default setting for the instrument is 0-0-0-0, which disables the password prompt. To
enable a password, select the option and input a 4-digit code other than 0-0-0-0.
Note: If you would like to reset the password, use the calibration password. This will reset the
password to the factory default (disabled).

Lowering Speed (in mm/s)
Your standard may specify a specific lowering speed. The options are 1, 2, and 5mm/s (10 mm/s
49-87 only)
Dwell Time (in seconds)
Your standard may specify a specific time to wait after the spindle motion stops on the sample
before it returns a result. The “0 seconds” option will report a result as soon as the machine
registers a stop. Dwell Times over 1 second will pause the motor in order to wait for the reading.
The options are 0,1,2,3,4,5, and 6 seconds.
Starting Units
This is the units that the machine will default to when powering on. The options are “μm” for
micrometers, “mils” for mils, “mm” for millimeters, and inches.
Record Stats:
The options for this setting are ON or OFF. Statistics can still be viewed if set to OFF, but no
new readings will be recorded.
Stat Threshold:
The options for this setting are OFF, 2 μm, 4 μm, and 6 μm. These are in metric because the
machine is internally a metric machine. Statistics will not be recorded if the reading is within the
tolerance band (+/-) around zero.
Zero Threshold:
This sets a small range around a reading of 0.00 to be reported as 0.00. For example: if the
machine is set to a Zero Threshold of 2 μm then any reading from -2 to 2 μm will return a reading
of 0 μm. The options for this setting are OFF, 2 μm, 4 μm, and 6 μm. These are in metric because
the machine is internally a metric machine.
Time:
This line contains several options
o 24Hr or A.M./P.M. – changes between 24 and 12 hour time
o Hours – adds one hour
o Minutes – adds one minute
o Seconds – resets the seconds to zero
Live Readings:
This option changes how the main screen displays the current gap. Turning Live Readings ON
will show a constant feed of the updated gap. Turning Live Readings OFF will cause the screen to
only update when it has a valid reading. These options will not change how the machine
communicates its readings with GraphMaster.
LED Pulse:
This will toggle the Cycle Button’s LED functions between constantly on and pulsing when a test
is being conducted. This has no effect on the machine’s function.

SERIAL DATA OUTPUT
These Testing Machine Inc. Micrometers (Thickness Gauges) output a string through a mini-USB
connector on the back panel of the instrument.
The USB host (PC) will need to be looking for serial data on one of its COM ports. The number of the
COM port will vary from host to host.
These are the settings needed to capture the serial data -
Baud rate: 9600
Data: 8 bits
Parity: None
Stop Bit(s): 1
Flow Control: None
Here are some serial string examples-
x Initial string - "CC5.1.1.13;"
o This is an identifier string used by our GraphMaster product. You can ignore it if you are
not using GraphMaster. It will only show up after powering on.
x After each cessation of downward motion, like the spindle coming to rest on a sample, the
machine will output a serial data string in the following format.
TM V00.01.02 49-87-00-000112345-67 00000000053+000004.370

o "+000004.370" - The reading itself in the units just specified. The '+' is there because the
machine can show negative values if zeroed while resting on something besides the
platen.
CALIBRATION
INTRODUCTION
This machine has been adjusted and calibrated at the factory. The 49-8X series micrometer has a
large portion of its calibration done via a PC. For that reason and the highly technical nature of
the calibration we recommend that it only be performed by factory trained personnel. When
adjustments and calibration are necessary, refer to the following procedures:
1. Use a set of TMI gauge blocks when calibrating or making adjustments. The set consists of
five steel gauge blocks of different sizes. (See Section 3 – Specifications.) These gauge
blocks are checked against standards that are traceable to the NIST. The part number for the
TMI gauge blocks is as follows:
For Model 49-85 and 49-86:
TMI # 35-12-02
For Model 49-87:
TMI # 35-12-03
2. Turn the micrometer on. Allow the micrometer to warm-up for approximately one half hour
before attempting to calibrate.
3. The pressure foot and the lower anvils must be clean and free of dirt. The gauge blocks must
be cleaned thoroughly with alcohol before use. Do not touch the working surface with
fingers before making any measurements.
PARALLELISM CHECK/ADJUSTMENT (pictures on following page)
Adjustment of parallelism should only be made by a trained professional
1. Always check the anvil parallelism first. Insert one half of the width of the .010 in. gauge
block between the anvils on the right side of the unit and take a reading.
2. Insert the same one half of the width of the gauge block between the anvils on the left side of
the unit. See Figure 1.
3. Repeat the above procedure for the front, back and center of the anvils.

4. For Model 49-85 and 49-86:*
The readings must be within 0.00004 in. of each other for the anvil and the pressure foot to
be considered parallel and no adjustment needs to be done.
For Model 49-87:*
The readings must be within 0.0002 in. of each other for the anvil and the pressure foot to be
considered parallel and no adjustment needs to be done.
5. If the parallelism measurements, as described in Section 9.2 – Steps 1 and 2, do not fall
within the tolerance range, the anvil needs to be adjusted. Underneath the base plate, there
are three leveling screws that attach the anvil to the base plate. Use an Allen key to adjust
the leveling screws while securing the nut with a 3/8 in. wrench.
For Model 49-85 and 49-86:*
Adjust the leveling screws until all readings are within .00004 in. (.001 mm) across the
anvil’s surfaces.
For Model 49-87:*
Adjust the leveling screws until all readings are within .0002 in. (.005 mm) across the
anvil’s surfaces.
When the adjustments are completed, recheck the parallelism.
* For instruments 49-86-00-0003 and 49-87-00-0003 perform three sets of readings, adjusting the
screws each iteration in order to establish a baseline parallelism. Only perform this parallelism
adjustment if measurements with gauge blocks placed in the visual center of the anvil are outside
the tolerances of the instrument’s calibration record.
MAINTENANCE
The TMI Digital Micrometers – 49-8X Series do not require oiling or special maintenance. A rise in
operating temperature is expected. The temperature will rise until it reaches operating temperature.
Keep the instrument clean and in an environment that is free of dirt and dust. For consistent test
readings, it is very important that the anvil and pressure foot are kept clean.
If the instrument is not in use for an extended period of time, a plastic cover should be used to protect
it from dirt and other foreign matter. The pressure foot and the anvil should not be in contact for
extended periods of time. Place a piece of paper, film, etc. between the pressure foot and anvil.
