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.

POWER: Turns unit on/off

UNIT: Home screen changes engineering units.

In Menus, moves cursor to the right position

MODE: Home screen, scrolls through 4 modes of
operation. In menus, moves cursor down in the list or
decreases a value

RESET: Home screen, resets the maximum
values. In menus, moves cursor up in the menu list or
increases a value

*

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).
