Digital Electronic Torque Wrench

This manual will help you to use the many
features of your new digital torque wrench.
Before operating the torque wrench, please read
this manual completely, and keep it nearby for
future reference.

● Buzzer and LED indicator for the 9 pre-set
target torques
● Water contact indicator
● Engineering units (ft-lb, in-lb, N-m, kg-cm)
selectable
● Stores up to 50 data les for recall and joint
torque auditing
● Auto Sleep after about ve minutes idle
● (2) AAA Batteries included
MAINTENANCE AND STORAGE
CAUTION: 1. Over-torque (110% of
Max. torque range)
could cause breakage
or loss of accuracy.
2. Do not shake violently
or drop wrench.
3. Do not use thewrench
as a hammer.
4. Do not leave thewrench in any place exposed to
excessive heat, humidity, or direct sunlight.
5. Do not use the wrench in water (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 thewrench away from magnets.
9. Do not expose thewrench 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.
BATTERY MAINTENANCE
1. When the wrench is not used for an extended
period of time, remove the battery.
2. Keep a spare battery on hand when going on a
long trip or to cold areas.
3. Do not mix battery types or combine used
batteries with new ones.
4. Sweat, oil and water can prevent a battery’s
terminal from making electrical contact.
To avoid this, wipe both terminals before
loading a battery.
5. Dispose of batteries in a designated disposal area.
Do not throw batteries into a fire.
ATTENTION:
To maintain accuracy, a one-year
periodic recalibration is recommended.
Please contact your local dealer for
calibration details.

ACTIVATION DURING SLEEP MODE
CAUTIONS:
During communication period (Send appears),
the sleep function is disabled.
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 PROTECTION
If the battery serial voltage is in low voltage
status, the wrench will display a battery symbol
and then turn off after a while.
WHEN CHANGING THE TYPE OF HEAD
If you use adifferent head with the wrench, the
reading on the display will be different for the
different length of the head. Please refer to the
following explanation.

The wrench will auto sleep after about 5 minutes
of being idle for power saving. Press to
wake up the wrench from sleep mode.
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.
D = D1 * (L3+L1) / (L3+L2)
Calibration Point
*1: The accuracy of the readout is guaranteed
from 20% to 100% of maximum range + /- 1 in-
crement. The torque accuracy is a typical value.
Calibration point is at the middle line of the
black circle area on the rubber grip. To maintain
accuracy, calibrate the wrench for a constant
time period (one year).
*2: Horizontal and vertical test.
*3: Environmental test:
a. Dry heat
b. Cold
c. Damp heat
d. Change of temperature
e. Impact (shock)
f. Vibration
g. Drop
*4: Electromagnetic compatibility test:
a. Electrostatic discharge
immunity (ESD)
b. Radiated susceptibility
c. Radiated emission

BEFORE USING THE WRENCH
BATTERY INSTALLATION
Remove the battery cover.
Insert two AAA batteries matching the
-/+ polarities of the battery to the battery
compartment.
Replace the battery cover and fasten it tightly
according to the following figures.
ATTENTION:
When opening the battery cover of your wrench,
you can see a viewing window for the water
contact indicator.Through this viewing
window, you can check if thewrench is
damaged by water penetration (the water
contact indicator turns red).
POWER ON AND RESETTING THE WRENCH
Press to power on the digital torque wrench.
You can press to reset the digital torque
wrench before using it.
ATTENTION:
If an external force is applied to the torque
wrench during the power-on/reset or wake up
period, an initial torque offset will exist in
the memory.
