USER’S GUIDE

Rev. Dec 2014

Keypad Functions:

Power ON - M key
U - Unit Selection - ft-lb, in-lb or Nm

- Zero Tare Torque (Press and hold key 3 seconds)

M - Mode - Manual power off, (Press and hold key 3 seconds)

▲ - Increase TARGET TORQUE value

(Press and Hold Key for rapid scrolling Up )
▼ - Decrease TARGET TORQUE value
(Press and Hold Key for rapid scrolling Down)

Automatic Power OFF after 5 minutes of idle time.

Note: For resolutions and decimal point, see table on back.

1. Setup:

a. Turn on the torque wrench by pushing the M key.

b. In TORQUE mode
Press the U key to view the units of measure.
Repeatedly push the U key to display the desired units
of measure, ft-lb, in-lb or Nm.

c. Manual Power off: Hold the M key for more than 5 sec

d. Push the ▲ or ▼ key to view the TARGET TORQUE
value. Use these same keys to increase or decrease to
the desired value.
During loading, the torque wrench will display applied
torque in real time. The yellow LED and the buzzer will

begin to pulse at 80% of TARGET TORQUE, and getting

faster as the TARGET TORQUE value is approached.

2. Application:

a. With the power on, insert the torque wrench driver into

the socket.

b. Apply torque load to the fasterner in either CW or CCW

directions. During loading, the torque wrench will display
applied torque in real time.

c. When the applied torque is within 4% of the TARGET

TORQUE value, the green LED, buzzer and vibrator
(optional) will output continuously. Stop applying torque,
as the installation is complete.

Release Indications:

Should the applied torque exceed the TARGET

TORQUE value by more than 4%, the red LED and
buzzer will alert continuously. If the torque applied is
exceeded 125% of torque range, the display will
indicate “OVER TORQUE.”

Temperature Drift: ± 0.0015%/F
Storage Temperature 0ºF to 125ºF
Operating Temperature 40ºF to 110ºF

Re-Order Components :

 DW Torque wrench P/N DW-XXXX

 User ‘s Guide P/N DTS-UG– DWA

Warning - Risk of flying particles.

 Read this entire User’s Guide before using

this torque wrench

 Always follow good professional tool practices.

Wear Safety goggles.

 Insure that all equipment is in good working

order and that ratings of the torque wrench,
tools and drives exceed the torque being
applied.

 Never use the torque wrench with the power

off.

 Never initiate ZeroTare with torque applied.

 Do not use the wrench as a breaker bar to

loose nuts, bolts or fasteners

 Save these instructions.

The “DW” series of electronic torque wrenches establishes a

new standard in threaded faster installation tools. It features the

latest state-of-the-art sensing and micro-controller technology in a
robust tool designed for the professional mechanic.

The DW series feature +/-1% accuracy of torque reading between
10% and 100% of full scale in both CW and CCW directions
which exceeds the ASME B107.28 Standard. The wrench is
usable down to 5% of full scale at +/-3% of reading precision. Its
integral 36-tooth ratchet drive provides strength as well as versa­tility in use. Three wrench sizes are available, providing 1/4in,
3/8in and 1/2in square drive ratchet heads, covering 20 in-lb to
250 ft-lb torque capacity.

The wrench is powered by two easily replaceable AA Alkaline
cells. This battery provides up to 400 hours of continuous opera-

tion. This electronic torque wrench is intended for use in industri-

al, aerospace, automotive repair, reliability labs and quality assur­ance environments.

One modes are featured:

 TORQUE - Display torque value in real time when torque is

loading and also show peak torque when torque is released.
