Caution!

Note the torque tester’s capacity before use and ensure that the capacity is not exceeded.
Producing a torque greater than 150% of the tester’s capacity can damage the internal sensor. An
overload can occur whether the tester is powered on or off.

The tester is designed primarily for the testing of threaded bottle caps, although other items can be tested
as well. Items that should not be used with the tester include potentially flammable substances or
products, items that can shatter in an unsafe manner, and any other components that can present an
exceedingly hazardous situation when acted upon by a load.

The following safety checks and procedures should be performed before and during operation:

1. Never operate the tester if there is any visible damage to the AC adapter or the tester itself.

2. Ensure that the tester is kept away from water or any other electrically conductive liquids at all
times.

3. The tester should be serviced by a trained technician only. AC power must be disconnected and
the tester must be powered off before the housing is opened.

4. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.

5. Wear eye and face protection when testing, especially when testing brittle samples that have the
potential to shatter under force. Be aware of the dangers posed by potential energy that can
accumulate in the sample during testing. Extra bodily protection should be worn if a destructive
failure of a test sample is possible.

Series TT01 Digital Cap Torque Testers User’s Guide

6. In certain applications, such as the testing of brittle samples that can shatter, or other applications
that could lead to a hazardous situation, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.

7. When the tester is not in use, ensure that the power is turned off.

2 POWER

The TT01 is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these
batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period
of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the
receptacle on the tester (refer to the illustration below). The battery will fully charge in approximately 8
hours.

USB connector

Serial connector

Power input jack

Caution!

Do not use chargers or batteries other than supplied or instrument damage may occur.

If the AC adapter is plugged in, an icon appears in the lower left corner of the display, as follows:

If the AC adapter is not plugged in, battery power drainage is denoted in a five-step process:

1. When battery life is greater than 75%, the following indicator is present:

2. When battery life is between 50% and 75%, the following indicator is present:

3. When battery life is between 25% and 50%, the following indicator is present:

4. When battery life is less than 25%, the following indicator is present:

5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing.

Several minutes after (timing depends on usage and whether the backlight is turned on or
off), a message appears, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone
audio indicator will sound and the tester will power off.

The tester can be configured to automatically power off following a period of inactivity. Refer to the Other
Settings section for details.

If battery replacement is necessary, the battery may be accessed by removing the cover attached to the
underside of the base.

3 SETUP

3.1 Mechanical Setup

Place the sample between the posts or jaws of the tester, and tighten, using the knob. Always ensure that
the sample is gripped firmly, however, excessive tightening of thin-walled closures may result in sample
deformation, possibly affecting test results. When the sample is secured, gradually exert torque on the
bottle cap by hand.

3.1.1 Sample gripping methods

Three different sample gripping methods are available, as shown below:

Posts (included) Flat jaws (optional) Adjustable jaws (optional)

3.1.2 Proper alignment

The center of the bottle cap should be positioned axially with respect to the center of the loading table.
Side loading or off-center loading may produce erroneous readings, and can damage the instrument.

3.1.3 Mounting to a bench

The tester can be mounted to a bench using the four threaded holes on the underside of the base.

3.2 Installing the USB driver

If communicating via USB, install the USB driver provided on the Resource CD. Installation instructions
may also be found on the CD or may be downloaded from

Caution!

5 OPERATING MODES

Caution!

In any operating mode, if the capacity of the instrument has been exceeded by more than 110%,
the display will show “OVER” to indicate an overload. A continuous audible tone will be sounded
(if tones are enabled) until the MENU key has been pressed or the load has been reduced to a safe
level.

Three operating modes are possible with the TT01 torque tester. To cycle between the modes, press

MODE while in the home screen.

5.1 Real time (RT)

The primary reading corresponds to the live measured reading.

5.2 Peak Clockwise (PCW)

The primary reading corresponds to the peak clockwise reading observed. If the actual load decreases
from the peak value, the peak will still be retained in the primary reading area of the display. Pressing

ZERO will reset the value.

5.3 Peak Counter-clockwise (PCCW)

Same as above, but for counter-clockwise readings.

6 CHANGING THE UNITS

The TT01 can display five different measurement units. To change the unit, select Units from the menu.
The display will list the available units, as follows:

UNITS

ozFin
* lbFin
kgFcm
Ncm
Nm

The tester will always power on with the unit selected in this sub-menu.

7 DIGITAL FILTERS

Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection
of 1 will disable the filter since the average of a single value is the value itself.

To access digital filter settings, select Filters from the menu. The display appears as follows:

Available settings: 1,2,4,8,16,32,64,128,256,512,1024. It is recommended to keep the current reading

filter at its lowest value for best performance, and the displayed reading filter at its highest value for best
stability.

8 SET POINTS

8.1 General Information

Set points are useful for tolerance checking (pass/fail) and triggering an external device in process control
applications. Two limits, high and low, are programmed in the tester, and the primary reading is compared
to these limits. The results of the comparisons are indicated via on-screen indicators as well as through
the three outputs provided on the 15-pin connector, thus providing “under”, “in range”, and “over”
signaling. These outputs can be connected to indicators, buzzers, or relays as required for the
application. On-screen indicators are described in the next sub-section.

8.2 Configuration

To configure set points, select Set Points from the menu. The display appears as follows:

SET POINTS
Upper Disabled
* Upper Enabled

5.00 lbFin
Lower Disabled
* Lower Enabled

3.50 lbFin

Either one, two, or none of the set points may be enabled. To toggle between the clockwise and counter­clockwise directions, press the DIRECTION key.

If two set points have been enabled, they are displayed in the upper left corner of the display. If only one
set point has been enabled, the word “OFF” appears in place of the value. If no set points have been
enabled, the upper left corner of the display will be blank.

When set points are enabled, the following indicators are shown to the left of the primary reading:

– the displayed value is greater than the upper

force limit (NO GO HIGH)

– the displayed value is between the limits (GO)

– the displayed value is less than the lower force

limit (NO GO LOW)

Note: Set point indicators reference the displayed reading, not necessarily the current live load.

8.2.1 Set Point Outputs Schematic Diagram

9 BREAK DETECTION

The break detection function identifies when the cap has been loosened, or other applications in which
the torque value has reached a peak, then dropped. Upon detection of the break, the tester can perform
several automatic functions, as follows:

1. Transmit the peak reading (Auto Output).

2. Save the peak value to memory (Auto Storage).

3. Zero the primary and peak readings (Auto Zero).

4. Toggle a pin.

Break detection functions and settings are configured from a central location, and apply to any mode in
which it is enabled. Refer to the Operating Modes section for details on configuring each mode.

13 CALIBRATION

13.1 Initial Physical Setup

The TT01 should be mounted to a
fixture rugged enough to withstand a
load equal to the full capacity of the
tester. Suitable calibration equipment
is required, and caution should be
taken while handling such equipment.
The AC1036 calibration kit is available
from Mark-10, shown at left.

Note the circular groove in the top
plate, shown at right, which
accommodates a cable for suspension of deadweights. The AC1036
calibration kit includes a cable with a diameter of 0.063 in [1.6 mm] for
insertion into this groove. The cable radius plus the circular groove
radius is equal to 3.333 in [84.66 mm]. Commonly available Imperial
deadweights may, therefore, be employed to achieve full scale
Imperial (i.e. lbFin) loads. For example, a 15 lb load multiplied by 3.333
in. will produce 50 lbFin of torque.

Metric unit calibrations are also possible through the configurable
calibration procedure described below:

13.2 Calibration Procedure

1. Select Calibration from the menu. The display appears as follows:

CALIBRATION

To invert the
display, press the
DIRECTION button,
then press ENTER.

2. Press DIRECTION to invert the display, if desired. ENTER to continue. The display appears as
follows:

CALIBRATION

Counter-clockwise:

The tester can be calibrated at up to 10 points in each direction. Enter the number of calibration
points for each direction (clockwise and counter-clockwise). At least one point must be selected
for each direction.

Note: To achieve the accuracy specification of ±0.3%, it is recommended to calibrate the tester at
5 or more even increments in both directions. For example, an MTT01-50 should be calibrated at
10, 20, 30, 40, and 50 lbFin loads in each direction.
