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 for various torque testing applications. 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.
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 TT05 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 will appear, “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
The matrix of threaded holes in the loading table allows for the mounting of specialized fixtures, as
required for the application. When designing and mounting the fixture, ensure that the axis of torque
aligns with the center of the loading table. Side loading or off-center loading may produce erroneous
readings, and can damage the instrument. The tester can be mounted to a bench via four threaded holes
located on the underside of the base.

4.3 Menu navigation basics
Most of the tester’s various functions and parameters are configured through the main menu. To access
the menu press MENU. Use the UP and DOWN keys to scroll through the items. The current selection is
denoted with clear text over a dark background. Press ENTER to select a menu item, then use UP and
DOWN again to scroll through the sub-menus. Press ENTER again to select the sub-menu item.
For parameters that may be either selected or deselected, press ENTER to toggle between selecting and
deselecting. An asterisk (*) to the left of the parameter label is used to indicate when the parameter has
been selected.
For parameters requiring the input of a numerical value, use the UP and DOWN keys to increment or
decrement the value. Press and hold either key to auto-increment at a gradually increasing rate. When
the desired value has been reached, press ENTER to save the change and revert back to the sub-menu
item, or press ESCAPE to revert back to the sub-menu item without saving. Press ESCAPE to revert one

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 beeps 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 TT05 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 TT05 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
lbFft
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 will appear as follows:

Two filters are available:
Current Reading – Applies to the peak capture rate of the instrument.
Displayed Reading – Applies to the primary reading on the display.
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 screen will appear as follows:
SET POINTS
Upper Disabled
* Upper Enabled
5.00
Lower Disabled
* Lower Enabled
3.50
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” will appear in place of the value. If no set points have been
enabled, the upper left corner of the display will be blank.
