Introduction

Use the portable DTT to test “click” type torque wrenches

(adjustable and preset), torque screwdrivers, dial indicating

and electronic wrenches.

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:

• 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.

DTT Digital Torque Tester

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.

• SCREWDRIVER (Peak Hold)

— Captures and displays the highest torque applied

(CW or CCW) until reset. Use to check torque

limiting screwdrivers.
