CDI Torque DIGITAL TORQUE TESTER (DTT) - Manual (Page 4)

OPERATOR INSTRUcTION
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 re-
applied 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.
USE OF AdAPTERS,
ExTENSIONS ANd UNIVERSALS
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.
