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

Auto power off
Reset the wrenchPower on and auto zero reset
■Set the wrench horizontally on a level surface and
let it sit without touching it, then gently press
to power on the digital torque-angle wrench.
■After power on, the LCD will flash first to do
auto zero-reset.
After doing auto zero-reset, a preset target will
show on LCD.
Attention:
If appeares during power-on process, it
means this wrench has been torqued to more than
110% of maximum torque.
Important!
When using the wrench in “ANGLE” mode the
wrench must be placed flat (horizontally) on table
or workbench before any attempt is made to
change values or to power up the unit. If the user
attempts these functions without following the
instructions above. The unit’s display will begin to
flash a series of four zeros in the top half of the
screen.In order to re-start the unit; press
■If necessary, Zero-reset will guarantee an
accurate measurement.
■After power on, button is for zero reset.
■Usually press to zero reset the digital
torque-angle wrench before using the wrench.
■In angle mode, keep the wrench steady without
any disturbance and press to do zero-reset.
■In torque mode, if an external force is applied
to the torque wrench during zero-reset period,
an initial torque offset error will occur.
If the battery serial voltage is in low, the wrench
will display a battery symbol and then turn off.
Replace batteries.
■The wrench will auto power off after about 2
minutes idle for power saving. Press to
power on the wrench again.
Cautions:
■During communication period (SEND appears),
the auto power-off function is disabled.
■If the wrench does not function normally or
appears, please go through the reset
process to reset the wrench.
■To reset the wrench, loosen the battery cap then
tighten it to re-start. After reset, remember to

2. Counting record: This feature counts how many
times the wrench has been used, but only counts
when applying up to 60% of max. torque. This re-
cord is not erasable until re-calibration. The feature
will count up to 65,000 measurements. Regarding
the number of measurements, the following figure
means the recorded count is 10100. (No-1 means
10000 times, No-2 means 20000 times reached
and so on…)

ANGLE MODE OPERATION
Note:
1. When angle is in auto initiate mode, please keep
the wrench steady without any disturbance.
2. After a short time, the angle function will enter
initiate mode and a flashing will appear.
3. When entering angle mode, press“up”or “down”
button to adjust preset torque and angle.
Adjusting preset torque to implies
snug point equals 5% of max. operation torque.
4. When releasing force the wrench in angle
mode, the display will show the corresponding
torque with flashing.
5. When 80% of the target degree is reached,
the green LED will begin to flash and the alarm
tone will beep intermittently.
6. When 99.5% of the target degree has been
reached, the alarm will change to a steady
tone and the green LED will stop flashing and
stay on. The red LED will also illuminate.

COMMUNICATION MAINTENANCE AND STORAGE
BATTERY MAINTENANCE
Precaution:
1. Communication function is only supported on
some models.Check the model no. and its spe-
cification 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.
■Change the wrench operation mode to “Send”.
(Please 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.
■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:
Refer to the uploader program user guide for
the detail operations.
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 calibrations.
