STB Overview STB (Static Transducer Bench) User Guide
12 (82) 9836 3078 01 Edition 2.11
2 STB OVERVIEW
The STB is ideal for controlling torque wrenches and screwdrivers according to ISO 6789 and SPC
standards or for calculating their Cm –Cmk.
The user-friendly software and the touch screen allow for immediate and simple operation.
The measurements taken are shown on a widescreen color LCD and the results are summarized by three
control lamps.
Since it is powered by batteries, the test bench may be used at any point along the assembly line.
Special PC software (Torque Supervisor) is available to allow the STB to be programmed with the tests to
be carried out during the week, and to receive their results. This software has been specifically developed
for controlling a large store of tools and allows Cm and Cmk or the test results to be filed in Statistic
Control, combining them with other information concerning the life of the tool (model, class, date of
purchase, presence in line or store, repairs, tests, etc.).

The tests carried out are therefore fully traceable, including the X/R cards and the "history" of the tool, an
indispensable requirement for compliance with the standard ISO 9000. Contact your Atlas Copco sales for
any further information regarding this software.
The drawers contain a set of accessories:
Set of adapters. Number and size of adapters depend from the bench
transducers configuration.
Reaction bar: The reaction bar is a useful tool to provide the operator
with greater comfort and safety during testing; when the reaction bar is in
use, the tool under test reacts on the bar instead of reacting on the
operator’s arm.
It must be always used for testing tools over 15 Nm.
European and US AC power cables.
PC CDs: Windows CD and driver. Keep it in a safe place; it might be
used by Atlas Copco Service personnel during bench maintenance.

3 USER INTERFACES
3.1 Static transducers
The standard STB bench features a set of static transducer SRTT-B:
Static transducers are designed to test:
Impulse power tools. When the
impulse tool has a shut-off valve, a
mechanical joint simulator is required.
Wrenches
Power tool, for those special cases in
which the test on the hydraulic would
be not possible. In this case, to
permit the tool to rotate, a
mechanical joint simulator must be
mounted on the static transducer.
To install a mechanical joint simulator, insert the simulator in the SRTT-B, and tighten the lever before
starting the test:
NOTE: Tighten the lever before entering the test window; the zero alignment is not performed
properly otherwise.
Tighten the lever, before
starting the test
Transducers

STB (Static Transducer Bench) User Guide User Interfaces
9836 3078 01 Edition 2.11 19 (82)
NOTE: For old benches, a static cell was installed instead of the SRTT-B:
The test philosophy on the static cell is the same of the one for SRTT-B. However, the static
cells are threaded and require the specific mechanical joint simulator (when a joint simulator is
needed).
3.1.1 Mechanical joint simulators
For each transducer SRTT-B on the bench, the two related mechanical joint simulators are provided.
Following are the two joint simulators provided for the SRTT-B 250 Nm:
TJ SRTT-B S –250
TJ SRTT-B H –250
Grey-Yellow
Grey-Black
Soft joint simulation
Hard joint simulation
For SRTT-B 1000 Nm, only one joint simulator is provided. Refer to the TJ SRTT-B User Guide for more
information about the joint simulators.

3.2 LCD Monitor with Touch Screen
The STB is equipped with a LCD monitor with touch screen.
To use all of the functions described in this manual, the touch screen can be used
to manage all of the operation (the bench keyboard/mouse, or external
keyboard/mouse can be used as well).
To edit a value in the bench software, proceed as following:
Press on the label (in this example Nom. Torque (Nm)) and the following virtual keyboard is shown:
