! Always wear safety glasses when operating this torque meter.
! Always use the proper range transducer for the application. Over torque
may result in damage to the transducer or breakage resulting in personal
injury. Under torque may result in an incorrectly tightened fastener that
could loosen resulting in failure at a later date.
! Do not use a transducer if it has been over-torqued.
! Never apply torque in a situation where tool breakage may result in a fall or
slip resulting in personal injury. Pulling on the wrench, as opposed to
pushing on the wrench may help avoid this situation.
! Always replace worn or rounded fasteners prior to applying torque. Slippage
may occur resulting in personal injury.
! Never try to recharge a non rechargeable battery.
! Never mount a transducer to a bench that is unstable or will tip when a
torque is applied.
! Never use a torque transducer with an impact wrench.

Introduction
The ELORA Electronic Torque Meter is a highly accurate torque analyzer and
production tool. Use it as a high end torque calibrator or bring it to the work
site to accurately apply torque to fasteners.
With the ELORA Electronic Torque Meter you only have to buy one
electronic module. Simply add ranges as you need them by purchasing
additional torque transducers.
You can use the 1% torque extensions to apply torque, check torque and also
to check torque wrenches. If you need more accuracy you can add the .5%
bench type transducers. These transducers are perfect for any calibration lab.
This Torque Meter uses the very latest in computer technology including a
small microchip installed on each transducer for true “plug and play”
recognition of the attached torque sensor. Simply attach the transducer, turn
the unit on and you are ready to go to work.
A full compliment of modes and functions combined with an easy to use
interface make this torque meter the perfect device for all torque applications.
There are some very special features inside of this meter that distinguish it
from the competition. For example, there is a “first peak” mode that allows
you to test and calibrate micrometer (clicking) type torque wrenches.
However, just having this software mode is not enough, you must also have
circuitry that is fast enough to capture the fast “click” of a torque wrench or
the ultra fast torque peaks of DC tools and pulse tools when in peak mode
(always use a joint rate simulator when testing power tools, joint rate
simulators simulate the application with springs).
The sampling rate of this torque meter is over 8,000 samples per second
rivaling any torque data acquisition system.
Memory for up to 1350 torque data combined with a direct rs232c com port
make this small unit a powerful data acquisition system.
Additionally, the torque meter has an industry leading triple 4 digit numeric
display that shows you the limits settings at all times and prompts you with
information during set-up.
These features combines with many other useful functions will make this the
last electronic torque meter you will ever need!
Thank you for purchasing the ELORA Electronic Torque Meter.
