It is recommend securing the torque tester to a work-
bench before operating. Immobilizing the analyzer is
critical for the safety of the operator as well as for the
accuracy of torque measurements during operation.
Mounting the unit to a fixed surface offers the most
secure way to immobilize the analyzer, and is
recommended when used at a permanent location. It
employs two spring loaded mounting screws from the
unit into the mounting surface.
Note: Remember that a loose torque tester during utilization can impact the validity of torque readings. Always make
sure the unit is secure before operating, as repeated usage may loosen the screws.

The EZ-TorQ Torque Tester offers three different modes of displaying torque information during operation
(Track, Peak and First Peak). The user will determine which mode is best suited for the application. The use of the three
modes is described below.
TRACK
This mode constantly tracks increasing or decreasing torque
variations. Use this mode to monitor varying torque on motors
and machinery. Also for calibration and testing of dial torque
products (small wrenches or dial screwdrivers).
PEAK
The display retains the highest torque applied. Use this mode
during calibration or testing of any hand type torque wrench
(dial, beam, and screwdriver), as well as power tools.
FIRST PEAK
The display holds the first detected torque peak applied.
Before any torque is applied, the display show dashes in the
torque value area. Once peak is detected, the display will
show the torque value. If a second peak is detected then it
will be displayed in the lower right (in small reverse video).
The function of this mode is primarily used for testing and
calibrating click type mechanical torque wrenches. The
tester captures the point where the wrench first clicks. As
additional force is applied a secondary torque is displayed.
This mode may be used for operator training on the correct
use of operating a click wrench. Always apply torque smoothly
to avoid false first peak readings.

Filter Selections
The EZ-TorQ II product utilizes hardware level low pass filters prior to A/D conversion and software averaging to clean
the main signal and remove undesired frequency signals which may be a result of noise which can occur during dynamic
motion. Three filter settings are provided, as described below.
1. Pan-Pacific (130Hz): At this frequency setting, the operator will see a decrease in torque values displayed as the
speed of the power tool is increased. The 130Hz frequency filter in conjunction with software averaging cuts off signals
above 130Hz, which will result in slightly lower torque values being displayed with increased RPM.
2. Mountz (170Hz): At this frequency setting, the operator will see limited or no change to the torque values being dis-
played as the speed of a power tool is increased. The 170Hz frequency filter in conjunction with software averaging cuts
off signals above 170Hz, which will result in little or no change to torque values being displayed with increased RPM.
3. ISO (500Hz): At this frequency setting, the operator will see an increase in torque values displayed as the speed of
the power tool is increased. The 500Hz frequency filter in conjunction with software averaging cuts off signals above
500Hz, which will result in higher torque values being displayed with increased RPM. The 500Hz frequency setting is
offered for customers seeking to test power tools in accordance the ISO standard ISO 5393.

POWER TOOL TESTING
The run down adapters (RDA) are designed to provide consistent and reliable torque readings for use with power driven
torque control tools. The RDA’s reduce the impact and irregular peaks that cause poor repeatability. Each RDA has an
effective torque range and will supply repeatable torque data within that range if used correctly.
Always use a quality joint rate simulator (run down adapter) when testing power tools in a simulated application. Use the
peak mode. The Peak mode is designed to meet the demanding frequency requirements for testing dynamic torque
applications.
Using Run Down Adapters
The EZ-TorQ includes a 1/4 Female Hex Square Drive Adapter which is used for testing hand tools. It also includes a
Run Down Adapter
Operation
1. The run down adapter is placed in-line between the tool drive and transducer of the torque tester.
2. The torque tester should be properly secured on a solid surface or a test bench.
3. Before each test run, the Input drive run down adapter (RDA) should be completely backed-up. (Unless using
Mountz AURA run down adapter)
4. The RDA is designed to run in clockwise direction only.
5. Apply torque until RDA is run down completely. Then note or save reading with the torque tester.
