Electronic Angle Torque Wrench
(with angle and memory function)
1. Electronic torque wrench is a very
precise instrument. It is only used to
tighten screws, bolts and nuts to the
required torque, and should be kept
properly.
Overview
2. In addition to changing the battery, do not disassemble and
install the wrench casually, incorrect disassembly and installation
may cause damage to the internal structure and make the torque
wrench unable to use.
3. Key features
● Accuracy:
- Torque: +/-2% from 20% to 100% of capacity;
- Angle: +/-1% of reading ±1° @ angular speed of 10°/s ~ 180°/s;.
● Units: Nm, Lbin, Lbft, Kgm.
● 4 Modes: Peak Torque, Peak Angle, Angle, Track mode.
● Peak value hold function for Peak Torque, Peak Angle and
Angle mode.
● Can set target torque value and target angle value.
● Led light and buzzer alarming.
● Can be operated continuously with automatic zero clearing.
● Memory function: Data storage to 1000 datas.
● Upload data to computer by USB port.
● Rechargeable by Micro-USB.
● Optional backlight, good for dark working condition.
● Torque error percentage display function.
● Battery level display.
● Automatically shuts off after 2 minutes of non use.
● Display, press keys:
Do not use it as a crowbar or as
a substitute for a ratchet wrench.
Do not use a torque wrench
as a hammer.
How to Use
1. Peak Torque mode
● Display shows 0, then press up or down key to set angle from 0°
to 9999°, increment is 1°. If set 0°, angle feature is not used. If set
angle, there are two kinds of status
:
1) Torque set 0, test with angle
only; 2) Torque set, then test with torque and angle. Press M to
confirm, Press C to quit, yellow light off.
● Set turn is Unit→Torque→Coefficient→Angle.
● While load force to 90% of set value,
yellow light turns on, buzzer beeps at a
certain frequency. While load force is
18% away from the set value, the
percentage starts to show, and gradually
decreases with the increase of torque.
● While it reaches ±2% of the set value,
the green light turns on and the beep
frequency of the buzzer increased, now
stop loading force.
● If continue loading force to more than
2% of set value, red light turns on,
buzzer keeps ringing, error pencentage
will show with triangle exclamation
mark . At this point, stop applying
force immediately.
● If force load is more than 10% of
capacity, display will show STOP, means
exceed maximum load, you have to
stop.
● After power on, use torque wrench under Peak Torque mode.
(For example
,
torque set 80 Lb.ft)
2. Peak Angle mode
● After unloading, the measured maximum torque value is
retained on the screen, and the color state light is also retained,
until the next load, the wrench will automatically reset to zero,
the state light will be off, and test will start again.
● After setting, press C to quit. The wrench should be placed in
a horizontal position. Four horizontal lines will gradually appear
on the screen. When the set value appears on the screen, it
can be used. (For example, it’s set to 60°)

How to Set
●
Press M into set menu, display shows
“unit”, yellow light on, press up or down key
to select unit, press M to confirm, enter
torque setting.
●
Display shows torque, press up or down
key to set torque value (if torque is set 0,
and you set angle, then it’s Angle mode),
press M to confirm, into coefficient
set.
●
Display shows 1, then press up or down key to set coefficient
from 0.6 to 1.2. If set 1, this feature is not used. The setting of the
coefficient K is calculated according to the following formula. The
coefficient function is marked as .
Coefficient function only works when
testing torque. Press M to confirm,
enter angle setting.
●
Press C to power on while no load.
●
Display will show last use, you can start to use it or set
。

Peak value hold
If the peak value is 80.2, it shows:
● In Peak Angle mode, default is from 5% of full load to start to
measure angle, increment is 1°, the displayed angle value will
increase along with rotation angle of torque wrench. Angular
velocity of wrench rotation should be 45 to 90 degree per
second.
● While angle is 8° away to the set
value, yellow light turns on, buzzer beeps
at a certain frequency. While the angle is
within ±18°of set value, the remaining
degrees from the set value will be
displayed at the lower left of the screen.
