TT Torque Tool Tester
Operation Manual
1) Overloading the transducer does not only damage the transducer but
may break the transducer head and could result in injury!
2) Torque ranges of 25 N-m and higher must be fastened properly with 4
bolts and nuts to a secure work surface, either horizontally or vertically.
Failing to do so may result in damage to the transducer and could result
in injury to the operator. Ranges 10 N-m and lower do not require mounting and may be used with the included rubber feat as long as precaution
is taken and unit is secured to prevent slippage.
3) Ensure that the torque wrench’s driver has engaged the transducer
socket properly when operating. The transducer head may be damaged
if not engaged properly and could result in injury to the operator.
4) Please make sure that you have safety gear and safety precautions
in place when applying torque to the transducer or when calibrating
the transducer.
5) Do not use a charger other than the unit supplied with the TT torque
tester. Using the incorrect charger may result in damage to the Ni-MH
rechargeable batteries.
NIDEC-SHIMPO INSTRUMENTS
The TT Digital Torque Tool Tester is a simple operation test instrument for quickly checking torque tool performance. The TT Series
provides exceptional accuracy for measuring torque on various
products including torque wrenches, manual screwdrivers, electric screwdrivers, pneumatic screwdrivers and other torque controlled power tools.
The TT’s provide long operation life and power flexibility with the
ability to work from the internal rechargeable battery or included
AC adapter. The TT’s have four modes of operation: Track for live
readings, Peak which records the highest level over a test, First
Peak which records the first peak reading over the test and Track/
Peak which shows both the live readings as well as the peak reading recorded.
The backlit display provides an analog bar graph on screen to
allow the user to know where the resultant torque is currently positioned compared to the full scale range of the unit. CW/CCW
icons along with programmable pass/fail LED’s ( HI/OK/LO) assist
users with ensuring proper test set up along with enabling a quick
determination of the results.
Every tester comes standard with USB and RS-232 output. The
TT’s software enables the uploading of data and the additional
statistical analysis with its auto-calculation of the selected values.
These excellent features make the TT Torque Tool Testers a valuable and versatile addition to the production and quality control
departments.

INTRODUCTION
Thank you for selecting the Nided-Shimpo TT series torque tool
tester. With correct use and regular re-calibration, the TT tool tester will provide many years of accurate and reliable service.
The Series TT can accurately measure torque in both the ClockWise (CW) and Counter Clock-Wise (CCW) direction. The TT provides simple user operation and is accompanied with software
and accessories to simplify your torque testing needs.
Before Use
Upon receiving the unit, please check that no physical damage
has occurred to the packaging, plastic carrying case or the instrument itself. If any damage is evident, please notify Nidec-Shimpo
immediately.
Operation Overview
The most commonly used features, such as displaying torque,
peak hold, zeroing and changing of displayed units, can all be
done by pressing a single dedicated key identified on the front
panel. See the Basic Functions section. To access the menus,
simply press the Menu key to access the tester configurations.
See the Main Menu section.
POWERING THE FIRST TIME
The TT is supplied with a set of Nickel Metal Hydride 4xAAA rechargeable batteries. For safety reasons during transportation the
batteries are shipped discharged. To obtain maximum battery life
we recommend that you charge them with the supplied charger/
adaptor for at least 14-16 hours when you first receive the instrument.
Battery Indicator
If battery level shows empty, a “ battery empty” message will be
displayed and the tester will power down automatically.
Important: Only use the adaptor/charger supplied.
USING THE TT
Fitting Accessories
If power torque tools are used, the rundown adapter provided can
be inserted to the torque transducer head. For wrench and torque
screwdrivers, you may need a matching adapter.
Power Up
To power up the tester press the ON/OFF key. A short self-test
runs during which the display will show the capacity in Newtons.

The TT re-zeroes itself during the self-test routine.
After the self-test, providing no load has been applied to the instrument, the display will show all zeroes.
*
Do not overload
the load sensor. This will cause irreparable
damage. Torques greater than 120% of full-scale will produce an
audible beep and OL symbol will blink on the display until the load
is released and the RESET key is pressed.
To power down the tester press the ON/OFF key.
*All the current settings are saved when the tester is turned off. The
tester will function in the same mode when powered up again.
Basic Functions
Clock-Wise(CW) torque is displayed by the right pointing arrow
symbol (see image below). Counter Clock-Wise torque is displayed by the left pointing arrow symbol (see image below).

Zeroing the Tester
During operation of the TT, it is often necessary to zero the display
so that minor errors do not become part of the measured reading.
Press and release the ZERO key.
Changing the Engineering Units
Depending on the capacity of your model, the following units
may be selected by pressing the UNITS key: N-mm, N-cm, N-m,
gmf-cm, kgf-cm, kg-m, ft-lbf, in-lbf. The TT automatically converts
readings as the new engineering unit is selected.
Changing the Mode
Press the Mode key to choose from the following modes of measure: Track, Peak, First Peak and Track/Peak
Track Mode
When “Track” appears in the display the TT will indicate live torque
readings in both directions as they are applied. See Figure 3a
Peak Mode
When “Peak” is selected the TT will show the maximum torque
recorded over the test. Subsequent increases in the peak will replace the existing peak value shown. See Figure 3c

MOUNTING: For proper operation and safety, it is necessary to
mount the torque tester with ranges of 25 N-m and higher. Fasten
the integral mounting bracket properly with 4 bolts and nuts to a
secure work surface. Mounting may be vertical or horizontal. For
lower torque ranges, this mounting bracket adapter is available
as an accessory if securing to a work surface is desired. To install
the bracket to the back of the unit, remove the four outer screws
with rubber feet. Disguard the rubber feet. Line up the adapter
plate’s four holes with the four outer threaded inserts on the bottom of the TT. Attach the adapter bracket with the four screws that
were previously removed. Tighten securely. Line up the adapter
plate’s four holes with the four outer threaded inserts on the bottom of the TT.
To upload all the values to the PC software program, highlight
UPLOAD ALL and press the ENTER key.
