Note:
*1: The accuracy of the readout is guaranteed
from 20% to 100% of maximum range
+ /- 1 increment.
The torque accuracy is a typical value.
Calibration line is at the middle line of the
dark spot on the rubber handle.
For keeping the accuracy, calibrate the
wrench for a constant period time (1 year).
And the accuracy is based on the zero
degree of offset from perpendicular drive.
*2: Use a special designed cable (accessory) to
upload record data to PC.
*3: Two AA batteries
(Toshiba carbon-zinc battery)
*4: Horizontal and vertical test
*5: One cycle means swing the torque
wrench from 0 Nm to maximum range
and back to 0 Nm.
*6: Environmental test:
a. Dry heat
b. Cold
c. Damp heat
d. Change of temperature
e. Impact (shock)
f. Vibration
g. Drop
*7: Electromagnetic compatibility test:
a. Electrostatic discharge immunity (ESD)
b. Radiated susceptibility
c. Radiated emission

BEFORE USING THE WRENCH
Battery installation
■Remove the battery cap.
■Insert two AA batteries matching the -/+
polarities of the battery to the battery compartment.
■Replace the battery cap and rotate it tightly
according to the following figures.

Battery and cap
Calibration point
D = D1x (L3+L1) / (L3+L2)
Power on and resetting the wrench
■Press to power on the digital torque wrench.
■Usually press to reset the digital torque
wrench before using it.
Attention
If an external force is applied to the torque wrench
during power-on/reset or wake up period, an initi-
al torque offset will exist in the memory.
Activation during sleep mode
Cautions
During communication period ( send appears), the
sleep function is disabled.
■The wrench will auto sleep after about 5 minutes
idle for power saving. Press to wake up the
wrench during the sleep mode.
Resetting the wrench
■Press together will reset the wrench.
■If the wrench does not function normally,
press together to reset the wrench.
Low battery voltage indicator
When changing the type of head
■If the battery serial voltage is in low voltage
status, the wrench will display a battery symbol
and then turn off after a while.
■If you use the different head of the wrench, the
reading on the display will be different for the
different length of the head. Please refer to the
following explanation.
■Reference dimension for each model:
D: The set torque
D1: The actual torque applied to the nut.
L1: The extended length
L2: The normal length
L3: The length from the fitting pin to
the calibration point.

COMMUNICATION
Precaution:
1. Communication function is only supported
on some models. Check the model no. and
its specification before using communication
function.
2. Do not insert the plug of communication
cable into torque wrench that does not
support communication function.
Connecting communication cable
Uploading record data
■Turn off power and then connect the accessory
cable between the COM port of PC and torque
wrench.
■Make sure the connection between PC and
wrench is normal.
■Press together to reset the wrench.
■Change the wrench operation mode to “Send”.
(Refer to “Peak Hold Mode Recorded Value
Review” section).
■Use PC to start the uploader program.
■In uploader program, first select the correct COM
port no.
■Next, select the file path to save the uploaded data.
■Finally, press “upload” button to transmit the
torque records to PC.
■The uploaded data is then shown on the column
and saved in the *.csv file. Use Microsoft Excel to
view *.csv file.
Caution:
Refer to the uploader program user guide for
the detail operations.

MAINTENANCE AND STORAGE BATTERY MAINTENANCE
■When the wrench is not going to be used for an
extended period of time, remove the batteries.
■Keep a spare battery on hand when going on a
long trip or to cold areas.
■Do not mix battery types or combine used
batteries with new ones.
■Sweat, oil and water can prevent a battery’s
terminal from making electrical contact.
To avoid this, wipe both terminals before loading a
battery.
■Dispose of batteries in a designated disposal
area. Do not throw batteries into a fire.
Caution:
1. Over-torquing (110% of Max. torque range)
could cause breakage or lose of accuracy.
2. Do not shake violently or drop wrench.
3. Do not use this wrench as a hammer.
4. Do not leave this wrench in any place
exposed to excessive heat, humidity, or
direct sunlight.
5. Do not use this apparatus in water (it is not
waterproof).
6. If the wrench gets wet, wipe it with a dry
towel as soon as possible. The salt in
seawater can be especially damaging.
7. Do not use organic solvents, such as
alcohol or paint thinner when cleaning
the wrench
8. Keep this wrench away from magnets.
9. Do not expose this wrench to dust or sand
as this could cause serious damage.
10. Do not apply excessive force to the LCD
panel.
11. Apply torque slowly and grasp the center
of the handle. Do not apply load to the
end of the handle.
Attention!
One-year periodic recalibration is necessary to maintain
accuracy. Please contact your local dealer for calibra-
tions.
