WARNING - To avoid damaging Torque &
Angle Wrench
• Never operate wrench when powered OFF.
Always power wrench ON prior to applying
torque.
• Do not press ON/OFF key while torque is
being applied.
• Never use this wrench to loosen fasteners.
3. To safely clean the torque wrench, wipe with a damp
cloth. NEVER use solvents, thinners, or engine
cleaners of any kind. NEVER immerse the torque
wrench in liquids of any kind.
4. Store torque wrench in protective tube at its lowest
torque setting. Do not force handle below lowest
setting.
INTROdUcTION
The CDI Torque & Angle wrench digitally displays and
monitors fastener torque and angular rotation (turn).
DISPLAY MODES
TORQUE - wrench functions as an adjustable torque
wrench.
ANGLE - wrench functions as an adjustable angle
wrench and simultaneously monitors torque to prevent
fastener or wrench overload.
SETTINGS - Adjustable torque and angle settings for
fastener installation specifications. The preset values
are programmable from 5% to 100% of full-scale
torque and 5 to 360 degrees of rotation. The scrolling
display rolls-over at both ends for convenient and
quick setting.
OVERLOAD - If the wrench is used beyond 100%
torque capacity, the audible tone will pulse rapidly to
warn the user to stop.
ZERO/RESET - Automatic self-check, torque zero and
angle reset at power-on and anytime the ON/OFF key
is pushed. (This is not a calibration check).
“- - - -” and the buzzer pulses. The wrench must be
reset by pushing the ON/OFF button.
In the angle display mode, the display shows the
angle PRESET value until 5% or more of full scale
torque is applied. Rotation is accumulated in angular
degrees. When torque is released, the accumulated
torque and angle values will flash alternately for 10
seconds. The display will continue to accumulate
if torque is reapplied within 10 seconds. This
allows time for reverse (ratchet) motion. When the
accumulated angle is within -10 degrees of preset
value, the Yellow LED turns ON. When the accumulated
angle is within -5 degrees of preset value, the buzzer
turns ON while the Yellow LED remains ON. When
accumulated angle is within -1 degree of preset value,
the Green LED turns ON, the buzzer sounds for 1/2
second, and the handle vibrates continuously until
torque is released. If accumulated angle exceeds
+2 degrees of the preset value, the Red LED turns
On, the buzzer pulses, and the handle vibrates until
torque is released, If angle preset is reached and
torque is released, angle accumulation is reset to
zero automatically. This allows moving on to the next
fastener immediately.
FUNCTION DETAILS - To PRESET the wrench, select the
UNIT of measure (Nm, ft-lb, in-lb or degrees) desired.
Use the UP and DOWN keys to set the required torque
or angle.
In the torque display mode, the display shows the
torque PRESET value until 5% or more of full scale
torque is applied. The display then switches to TRACK
mode showing the applied toque in real time. When
applied torque is within -10% of the preset value, the
Yellow LED turns ON. When applied torque is within
+/-4% of the preset value, the Green LED turns ON,
the buzzer sounds for 1/2 second, and the handle
vibrates continuously until torque is released. If torque
is re-applied, the display will immediately switch to
TRACK mode. If torque exceeds +4% of the preset
value, the Red LED turns On, the buzzer pulses, and
the handle vibrates until torque is released. Exceeding
125% of full scale the display will lockup showing
The yellow LED illuminates within 10% of target torque.
The green LED illuminates within 4% of target torque. Continuous buzzer
sounds when target is reached.
The red LED illuminates 4% beyond target torque, indicating fastener was
overtorqued. Rapid “alarm” buzzer sounds.

USE OF AdAPTERS,
ExTENSIONS ANd UNIVERSALS
1. Turn the wrench ON by momentarily pushing the
ON/OFF key. The display will return to the mode of
operation and preset values previously set up.
2. To change the mode of operation, TORQUE or
ANGLE, scroll the selections by momentarily
pushing the UNITS key. The preset values for each
mode will be displayed.
3. Use the UP and DOWN keys to change the preset
values.
(Note: TORQUE is also measured in ANGLE mode).
4. Grasp the center of the handle and slowly apply
torque to the fastener until the Green LED, audible
buzzer, or handle vibration alerts you to stop.
5. Release torque. Note the PEAK reading flashing on
the display for 10 seconds, unless torque is reapplied or the ON/OFF key is pushed to clear the
display.
6. In ANGLE mode, place the wrench on a flat surface
during ZEROTARE.
7. The Bar Graph shows measured TORQUE or ANGLE
as a percentage (10-100%) of Preset.
Anytime an adapter, extension or universal is used
with a torque wrench in such a way that the fastener
distance is different that the torque wrench square
drive distance, an adjustment to the set torque is
required to get proper fastener torque.
Fastener torque equals torque wrench square drive
torque. Wrench setting is equal to desired fastener
torque.
Fastener torque equals torque wrench square drive
torque. Wrench settIng is equal to desired fastener
torque.
Fastener torque is greater than torque wrench square
drive torque. Calculated setting will be lower that
desired fastener torque.
Fastener torque is less than torque wrench square drive
torque. Calculated setting will be higher than desired
fastener torque.
When using a
universal or
wobble extension,
do not exceed
more than 15
degrees & offset
from perpendicular
drive. Do not use long extensions with the flex-drive.
