CDI Torque HEAVY-DUTY TORQUE AND ANGLE Electronic Torque Wrench - Manual (Page 3)

INTRODUcTION
The CDI Heavy-Duty wrenches digitally display and
monitor 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).
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
and the buzzer sounds for 1/2 second 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 and
the buzzer pulses until torque is released. Exceeding
125% of full scale the display will lockup showing
“- - - -” 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 and the buzzer sounds for
1/2 second until torque is released. If accumulated
angle exceeds +2 degrees of the preset value, the
Red LED turns ON and the buzzer pulses 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.
