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 torque tools, 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.
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 TT02 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
Caution!
Do not use Series TT02 torque testers with pneumatic or impact tools.
3.1 Using manual torque tools
Use a bit adapter of appropriate size and place the tool into the receptacle, as shown in Fig. 1 below.
Gradually exert torque by hand until the desired status is achieved (ex. click, slip, etc.).
Fig. 1
Typical manual torque tool test
3.2 Using motorized torque tools
It is highly recommended to use a rundown fixture when testing motorized torque tools, as shown in the
illustrations below. Use a bit adapter of appropriate size and place the tool into the rundown fixture, as
shown in Fig. 2. Activate the tool until the desired status is achieved (ex. click, slip, etc.). For best
performance, the Digital Filter should be configured to its lowest possible setting. Refer to the Digital
Filters section for details.

3.3 Proper alignment
Align the tool axially with respect to the square drive in the receptacle. Side loading or off-center loading
may produce erroneous readings, and can damage the instrument.
Note: It is normal to detect a small amount of mechanical play in the receptacle.
3.4 Mounting to a bench
The tester can be mounted to a bench for horizontal or other orientations using the optional bench
mounting kit, as shown below:

2A and 2B refer to First and Second peaks, respectively, when the tester is in
First / Second Peak mode (see First/Second Peak section for details). In
either mode, press ZERO or power off to reset these values.

Analog indicator to identify when an overload condition is imminent. The bar
increases either to the right or left from the midpoint of the graph. Increasing
to the right indicates clockwise torque, increasing to the left indicates counterclockwise torque. If set points are enabled, triangular markers are displayed
for visual convenience. This indicator reflects the actual torque, which may
not correspond to the primary reading (depends on operating mode). The
ZERO key does not reset the load bar. See Operating Modes section for
details.

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 torque has been reduced to a
safe level).
Five operating modes are possible with the TT02 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 torque 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, for counter-clockwise readings.
5.4 First / Second Peak (2PK)
Displays first and second peaks for the same measurement direction. This function is used to identify the
true peak before tool rotation reaches a hard stop, causing an artificial spike in torque. This mode will only
appear if enabled in the First / Second Peak menu.
5.5 Break Detection (BRK)
Arms the tester for automatic data output, automatic zero, and/or automatic data storage upon tool slip or
click, as configured in the Break Detection menu. This mode will only appear if enabled in the Break
Detection menu.
6 CHANGING THE UNITS
The TT02 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.
