CDI Torque COMPUTORQ II Electronic Torque Wrench - Manual (Page 6)

OPERATING INSTRUcTIONS
OPTIONS
A. After data is sent, or TO CLEAR MEMORY
ANYTIME, during this process press
Button #1 (clear/zero) TWICE in rapid
succession. An audible tone is sounded
indicating all stored data in memory will
be erased. The display will read “CLr”
and then all zeros.
PLEASE NOTE: Data being sent to a
printer or computer may be terminated
at any time by pressing Button # 2 (store
/ send).
B. To continue to add more values to the
existing memory, press Button #4
(set-up) and take more torque readings.
PLEASE NOTE:
A. To prevent stored torque values in memory from
being cleared erroneously, an operator must first
have recalled torque values on the LCD by pressing
Button #3 (recall) and then pressing Button #1
(clear/zero) twice.
B. While applying a load to the fastener, in “TRACK’
mode, care must be used by the operator to assure
that the applied torque is “held somewhat steady”
while Button #2 (store/send) is pressed. Computorq
II’s microprocessor will capture and store the values
on the display the instant Button #2 (store/send) is
pressed.
• TO TURN WRENCH “OFF”:
Press and hold Button #1 (clear / zero) for
approximately 2 seconds. An audible tone will signal
and the display will turn blank. If the wrench is to be
stored or not used for prolonged periods of time, slide
the ‘off-on” switch to the “off” position to conserve
battery life.
• BAR GRAPH FUNCTION
A ten segment bar graph on the top of the LCD is a
reference for the operator of the relative position of
applied torque to the full range of the wrench. This is
whether in track or peak modes.
OPERATING INSTRUcTIONS
If there is a TARGET torque value with percentage
tolerances, the ten segment bar graph will show full
scale AT THE TARGET VALUE - not the wrenches’ full
scale.
PLEASE NOTE:
A. The next time the wrench is turned “ON”, the same
parameters as last used will still be active until
changed.
B. If “Err” is displayed on the LCD (flashes at any time)
the wrench should be turned off and then on with NO
LOAD on the wrench. If “Err” continually appears on
the LCD after performing the above procedure, return
the wrench to the factory for evaluation.
IMPORTANT NOTICE: Please read all safety and
operational cautions and warnings contained in this
manual before using your electronic torque wrench
found at the beginning of this manual.
COMPUTORq II is, in effect, a transducer. Torque
transducers are sensitive measuring instruments.
“Over Torquing” past the useable torque range of the
wrench may result in permanent damage. Always load
the wrench slowly and do not exceed the useable range
in any application.
