INTRODUcTION
Use the portable DTT to test "click" type torque wrenches
(adjustable and preset), torque screwdrivers, dial
indicating and electronic wrenches.
C
The tester features a swivel-neck LCD display with
selectable English or Metric units of measure. 11 models
are available, ranging from 10-100 in.oz. to 60-600 ft.lb.
The DTT displays torque values using a built-in
straingaged transducer with an accuracy of ±0.5% of
indicated test value from 10% to 100% of rated capacity,
in clockwise (CW) and counter-clockwise (CCW) directions.
TORqUE VALUES
Capture and display torque values in one of four
selectable modes:
• CLICK ADJUST (First Peak)
— Responds to the drop-off in torque caused by the
"click" of an adjustable wrench. FIRST PEAK torque
is measured, captured and displayed (CW or CCW)
just prior to the drop-off, even if click torque is
subsequently exceeded.
• CLICK PRESET (First Peak)
— Responds to the drop-off in torque caused by the
"click" of a preset wrench. FIRST PEAK torque is
measured, captured and displayed (CW or CCW)
just prior to the drop-off, even if click torque is
subsequently exceeded.
• DIAL / ELECT (Peak Hold)
— Captures and displays the highest torque applied
(CW or CCW) until reset. Use to check dial indicating
and electronic torque wrenches.
• SCREWDRIVER (Peak Hold)
— Captures and displays the highest torque applied
(CW or CCW) until reset. Use to check torque limiting
screwdrivers.
This manual contains general information. Operating
features and specifications may change without notice.
