are highly dependent upon the power requirements of the
bridge excitation circuitry. At a minimum, the instrument
requires approximately 17 watts of power. A fully loaded
instrument employing the maximum excitation current
requires up to 26 watts of power.

ENCLOSURE
The Model 8000-8-SM enclosure is constructed of aluminum
alloy. The enclosure is designed to provide strength,
durability, and to minimize RF emissions and susceptibility. The Micro-Measurements A123 System Voltage
Calibration (VCAL) Card is available as an accessory and
provides the ability to perform a system-level calibration
of the entire measurement circuit without the need to
return the system to the manufacturer or metrology lab.
The gain and offset of each channel can be calibrated.
The A123 is calibrated at the factory to NIST-traceable
standards and does not need to be present in the system
during normal operation. A benefit of on-board system
calibration is the ability to calibrate the system under the
actual operating conditions, thereby minimizing errors due
to environmental conditions.

Milling Guide for Residual Stress Measurements

DESCRIPTION
A predominant factor contributing to the structural failure
of machine parts, pressure vessels, framed structures,
etc., may be the residual “locked-in” stresses that
exist in the object prior to its being put into service.
These residual stresses are usually introduced during
manufacturing, and are caused by processes such as
casting, welding, machining, heat treating, molding, etc.
Residual stress cannot be detected or evaluated by
conventional surface measurement techniques, since the
strain sensor (strain gage, photoelastic coating, etc.) can
only respond to strain changes that occur after the sensor
is installed.
The most widely used practical technique for measuring
residual stresses is the hole-drilling strain gage method
described in ASTM Standard E837. With this method,
a specially configured electrical resistance strain gage
rosette is bonded to the surface of the test object, and
a small shallow hole is drilled through the center of the
rosette. The local changes in strain due to introduction
of the hole are measured, and the relaxed residual
stresses are computed from these measurements.

RJ45-STA

Screw Terminal Adapter

DESCRIPTION
The RJ45-STA allows for an easy, reliable and reusable
connection to all Micro-Measurements instruments that
utilize the RJ45 connector. The RJ45-to-screw- terminal-
block adapter has a 6-inch pigtail to allow manipulation
and access to the screw terminal block, even when the
RJ45 is connected to a data system. The screw terminal
block accepts up to 22 AWG wire. Requires a 2 mm
slotted screwdriver.

COMPATIBLE WITH:
• System 7000 StrainSmart® Data Acquisition System
(strain gage, high level and LVDT inputs)
• System 7100 StrainSmart® Data Acquisition System
(strain gage, high level and LVDT inputs)
• System 8000 StrainSmart® Data Acquisition System
• System 9000 StrainSmart® Data Acquisition System

Crimping tools for RJ45 crimp connectors

DESCRIPTION COMPATIBLE WITH:
RJ45 crimp connectors are IDC (Insulation Displacement • System 7000 StrainSmart® Data Acquisition System
Contact) connectors. The terminals pierce the wire (strain gage, high level and LVDT inputs)
insulation and make gas-tight connections to the • System 7100 StrainSmart® Data Acquisition System
conductor for ultimate reliability. To achieve this a suitable (strain gage, high level and LVDT inputs)

damage to the mating input connector on the instrument; • System 9000 StrainSmart® Data Acquisition System
failure to achieve this can result in an expensive repair. (strain gage and high level inputs)
Properly installed, RJ45 connectors are fast to install and • D4 Data Acquisition Conditioner
offer excellent long-term reliability. • MultiDAQ Strain Gage Data Acquisition Device
Plier-type crimping tools are unreliable because it is
possible to release the tool before the terminals are fully
pressed, and can cause RSI (repetitive strain injury) due
to the amount of force required. Ratchet tools require low
levels of force and release only when fully depressed.
They are ideal when large numbers of connectors are
required to be fitted. We offer two types of crimping tool:
MMA106, RJ45 Crimping Tool for Unshielded
Modular Plugs – ideal for use with low-cost unshielded
connectors where measurements are static or have low
levels of environmental noise. For use with our MMA108
unshileded RJ45 connectors.
MMA115, RJ45 Crimping Tool for Shielded Modular
Plugs – shielded connectors are essential for dynamic
measurements where environmental electrical noise can
affect the measured data. For use with our MMA115
shielded RJ45 Connectors.
