This manual will help you use the many features of this device. Please read the manual completely
before operating the meter and keep it nearby for future reference.
Due to torque / angle measurement and calibration requiring strict certification, torque instruments
must possess good temperature, precision, resolution capabilities, and must also be able
to correct disturbances (ESD and EMI). And while the characteristics of peripheral
components must meet certain specifications, measurement chip must also meet specifications.
Because of this, the simplification of peripheral passive elements allows an instrument to
accurately measure torque / angle values, which will not only save cost, but also improve
maintenance and assembly quality, and reduce the chance of damage while in use.
Simple multifunctional operation, vibration resistance, torque / angle value presetting, measuring
unit selection, mode selection, data memory & storage, digital up & down increments,
power-saving mode, color changing display & audible alarm, etc.

5.1 Power and Clear
Make sure the device is standing perfectly still and press the C button to turn it on. After the
backlight LED flashes, the display will show 0000 (auto-zeroing) and then enter the operating mode.
If the device detects it is not standing still, the display will keep continuously showing 0000 from left
to right until the device is completely static. When the four zeros are displayed at the same time for
three consecutive times, then the device will enter operating mode.
When the meter is used for the first time, after entering operating mode the display will show the
lowest operating value, the units will be set to N.m, memory will be set to #1, mode will be set to
Track "T" and the battery scale will show current battery life. (All 30 memory data sets will be set
the same way.)
Turn Off: Press C button and hold for 3 seconds to switch off.
Clear: Press C button to reset (with device turned on).
5.2 Unit selection
This device works with international metric units of N.m and Kgf.cm and British units of lbf.in and
lbf.ft. Press the U/S button to select desired unit (preset unit is N.m).

5.3 Memory Function
All memory data sets are preset to the maximum operating value in N.m. To select a memory data
set press the M button, the digit at the bottom right corner of the display (M-01) will start blinking;
use ▲ (up) or ▼ (down) to scroll through memory data sets (up and down buttons can be held
down for continuous increase or decrease). Press M button to select desired memory data base;
after selection digit will stop blinking.
5.4 Track mode T / Peak Hold Mode P / Angle mode A
Track mode :
After setting a target torque value (for example 50 N.m), the user will gradually apply force to the
wrench until reaching desired target. When force is applied, the displayed torque value will start to
increase from zero and vary as the user applies different amounts of force; the torque reading will
increase as applied force increases and decrease as applied force decreases. If there is no force
applied to the wrench the torque reading will go back to zero.
Peak mode :
After setting a target torque value (for example 50 N.m), the user will gradually apply force to the
wrench until reaching desired target. When force is applied, the displayed torque value will start to
increase from zero and the device will hold on the display the maximum torque reached. If the user
decreases the amount of force applied, the torque reading will not decrease. After reaching a
determined torque value, the display will hold that reading and blink for 10 seconds (no actions or
buttons will be effective at this time) and automatically go back to show the original setting data,
the user can also press C button to return to the selected value or apply force again and the torque
reading will restart form zero.
Angle mode :
After setting a target angle value (for example 50°), the user will gradually apply force to the wrench
until reaching desired target. When force is applied, the displayed angle value will start to increase
from zero. After reaching a determined angle value, the display will hold this reading and begin
blinking (during this time the display will also show the amount of torque applied to reach said
angle; torque units can be chosen by user.) If the user needs to swing back the wrench to complete
angle target, the device will automatically hold the angle value reached on the previous swing and
add the angle value from the next swing. The angle reading on the display will change to the preset
value after 10 seconds if no applied force detected, but it will show the latest angle value
automatically when force is applied again. The user can press the C button to clear the angle value,
and the angle reading will start from zero when applying force.
5.5 Range Selection for Pre-set Memories
Torque or angle values can be freely selected as long as force is not being applied or memory
selection has not been performed. After completing torque or angle measurement in either mode,
the selected target value will be displayed.
5.6 Scroll ▲(UP) / ▼(DOWN) Selection
When setting a target value, pressing the ▲ (up) button once will cause the value on the far right of
the display to increase by one unit; pressing and holding the button will cause the value to increase
continuously. Pressing the▼ (down) button once will decrease the value on the far right by one
unit; pressing and holding the button will decrease the value continuously.
5.7 Screen flip
By pressing the button the screen will flip 180°.
5.8 LCD Display/ Monitor Color Changing & Audible Buzzer Warning
▪ In track mode, for example when the target torque value is set to 20 N.m, the reading will begin to
increase from zero as soon as force is applied. Below 80% of target value, the display backlight will
be green. Above 80%, the backlight will turn orange and the buzzer will start to beep. As the torque
reading continues to approach target value, the beeping will be faster; when 100% is reached, the
backlight turns red and the beep becomes continuous. Red backlight and continuous beep will also
be present above 100% target. Beeping frequency will decrease as applied force decreases.
▪ In peak mode, the warnings behave the same as in track mode, but the LED backlight and
beeping will stop once applied force ceases.
▪ In angle mode, for example when the target angle value is set to 20°, the reading will begin to
increase from zero as soon as force is applied. Below 80% of target value, the display backlight will
be green. Above 80%, the backlight will turn orange and the buzzer will start to beep. As the angle
reading continues to approach target value, the beeping will be faster; when 100% is reached, the
backlight turns red and the beep becomes continuous. Red backlight and continuous beep will also
be present above 100% target. Beeping frequency will decrease as applied force decreases.
5.9 Battery Life Indicator
The battery life indicator is shown on the display and it consists of four bars. A battery voltage of
3V or above is shown as a complete charge (four bars), a voltage lower than 2.8V is shown as
three bars, lower than 2.6V is shown as two bars and less than 2.4V is shown as one bar; when
voltage is lower than 2.3V, all functions will cease and the device will turn off after the battery
indicator flashes for 5 seconds.
5.10 Reset Memory Function
Press and hold the C button + ▼ (down) button; after 5 seconds, all values stored in memory will
reset to factory preset values.
5.11 Backlight Switch
Press the C button + ▲ (up) button to turn the display backlight on or off. The backlight is
preset as on.
5.12 Reset
To ensure accurate readings, always press C button to reset the device before using it. This reset
function is disabled while in use to prevent errors in measured values.
5.13 Power Saving Mode
The device will automatically enter power saving mode after 2 minutes of inactivity. Press C button
to exit power saving mode.
5.14 Overload Warning
Switch off and back on or reset device if screen continues to display 110%. This means device has
been forced to 110% of its maximum torque specification. Overloading may result in damages or
loss of accuracy.
