1.0 INTRODUCTION
1.1 System Overview
The MCS7500C Calibration System allows users to check torque accuracy, run calibration tests, and create
calibration certificates for bolting tools. The MCS7500C is designed for corded electric, hydraulic and
pneumatic tools, such as the Enerpac PTW- and ETW-Series Torque Wrenches, as well as similar controlled
bolting fastening systems.
Not Suitable for use with battery or impact tools
The calibration system is a calibrated instrument qualified in a UKAS certified laboratory. The accuracy of
the MCS7500C is calibrated to meet or exceed: 1% of Full Scale Deflection (FSD) from 2% to 8% of torque
range and 1% of reading from 8% to 100% of torque range.
Upon delivery, all components must be inspected for damage incurred during shipping. If damage is found,
the carrier should be notified at once. Shipping damage is not covered by the Enerpac warranty.
Please read the full Instruction Sheet before using the MCS7500C.

1.2 Main Components
Run down fixture and transducer – The run down fixture and transducer are designed specifically for the
testing of constant rotation controlled bolting tools. The MCC7500 features a 1.5" female square drive that can
accommodate other size square drive tools with the use of adaptors. The dynamic fixture provides a fastening
solution that is similar to real life applications. An integrated transducer measures the torque and communicates
the results to the digital display module. The run down fixture can be adjusted vertically to accommodate
various tool designs.
Base plate - The base plate houses the run down fixture, reaction stop, and digital display module. It features
three sturdy legs, end slot to transport the unit, and can be fastened down to a flat surface.
Reaction stop – The reaction stop functions as a counterpoint to the reaction arms of the wrench. The torque
wrench being calibrated is positioned with the reaction arm in between the wings of the reaction stop. The
MCS7500C features a standard reaction stop that will accommodate most pneumatic and electric tools,
including the PTW-, ETW-Series and many competitive tools. It also features a special reaction post for tools
with configurations that won’t work with the standard reaction stop.
Digital display module –The digital display module facilitates the display, collection, archiving, and processing
of torque readings. The module can run o battery power or plugged into an outlet. Each MCS7500C is equipped
with a global outlet adaptor that allows the tool to be used with many electrical systems.
Fig. 2 - Digital Display
When used with the Torque To Spreadsheet (TTS) software, the digital display module can be attached to a
computer with a USB plug (see Section 1.3).
The TTS software is included with the standard MCS7500C package. The MCS7500C can interface with the
test stand using a USB cable. The software facilitates the calibration testing of torque wrenches and can be
used to create calibration certificates. Windows 7/8/10 is required to install the TTS software. Microsoft Excel is
required to export and display the torque readings.
