Dear customer,
We appreciate your support purchasing our product – digital torque adapter. In order to learn
the advantages of the product well, please kindly read the instruction carefully before you
adjusting to any settings. Also please keep this manual for your reference in the future.
4.1 Battery installation
4.1.1 Open battery cover.
4.1.2 Insert battery, make sure
polarity is correct.
4.1.3 Replace the battery cover.
4.2 Low Voltage Notification
If the system detects a voltage level of less than 2.3V, a
battery icon will appear at the upper right corner of the
screen, and the system will shut down a few seconds
later.
1. Product Overview
As a result of torque measurement and calibration requires strict certification, torque
instruments must possess good temperature, precision, and resolution capabilities, and must
also have the ability to correct for disturbances (ESD and EMI). And while the characteristics
of peripheral components must meet specification requirements, measurement chip
specifications must also meet requirements. Because of this, the simplification of peripheral
passive elements can enable an instrument to accurately measure torque values, which will
not only save cost, but also improve maintenance and assembly quality, and lessen the
chance of damage to the used objects.
2. Product Features
Simple multifunctional operation, vibration resistance, can preset torque value, unit switching,
mode switching, memory & storage, digital up & down increments, power-saving mode, LED
flashing & audible alarm, etc...
3. Technical Specifications
4. Before using the adapter
This product provides international standard metric units of Nm, metric units of Kgf.cm, and
British units of lbf.in and lbf.ft. The units will change each time the U/S key is pressed, in the
order of Nm,Kgf.cm, lbf.in, and lbf.ft; the preset units are Nm.
5.2 Unit Switching
(F) Mode: (preset as tracking mode at time of first use)
After setting a value (assuming the value is 50Nm), the force applied by the wrench
will gradually increase from 0000. When force is applied, the displayed value will
change as the user applies different amounts of force; the reading will increase as
force increases, and decrease as force decreases. The reading will jump to 50Nm
when the user relaxes his grip and lets up.
5.4 (F) Mode/ (K) Mode/(A) Mode (Angle Series)
Values can be freely selected as long as force is not being measured or memory selection
has not been performed. After completing torque measurement in either mode, the selected
value can be displayed.
5.5 Measurement Range Selection
Pressing the ▲ (up) key once will cause the value on the far right to increase by one;
pressing the key continuously will cause the value to increase continuously. Pressing the
▼ (down) key once will cause the value on the far right to decrease by one.
5.6 ▲( U P ) / ▼ ( D O W N ) selection
(There will be a beep each time a key is pressed.)
In Track mode, the two LED light will function as green and red. Assume that the torque
value is set at 20Nm. When the user starts applying force to the wrench, the value changes
from 0000. When the force reaches 80% of the set value, the green light starts to flash, and
the buzzer starts to sound. When the torque value approaches the set value, the green light
flashes faster and the buzzer sounds faster. When the force reaches 100% of the set value,
the green light comes up permanently, and the buzzer sounds continuously. When the force
exceeded the set value(101%) , the red light comes up, and the buzzer continues to sound.
The value decreases when the force applied to the wrench is decreased.
5.7 LCD Backlights Warning & Buzzers
(K) Mode:
After the value is selected (assuming 50Nm is selected), when the wrench is applied with
force, the value increases from 0000 upwards. When the force is applied by the force, the
displayed value will change according to the force of the applying force, and after the force is
completely stopped, the value is displayed. For the final torque value, flashes for 10 seconds.
After 10 seconds, continue to apply the torque value will automatically accumulate (at this
time, any action and button are invalid). After 10 seconds, no force will continue to return to
the selected value, or press C can be returned to the selected value.
(A) Mode (Angle series):
After setting a degree (assuming is 50°), the force applied by the wrench will gradually
increase from 0°. When the force is exerted, the displayed value will change according to the
angle of the force applied, and the force will stop completely. The display value is the final
angle value and torque value. The angle value and torque value are interactively displayed.
Flashing for 10 seconds. Continue to force the angle value within 10 seconds will
automatically accumulate (in this case, any action and buttons are invalid). After 10 seconds,
no continue to force automatically return to the selected value, if not press C key to clear,
then the next time the force is applied, the angle value will continue to accumulate from the
previous value, until over the selected value will automatically clears the accumulated value,
switch mode and shutdown it also clears the angle accumulated value.
All memory data sets are preset as the maximum value. To set a memory value, press the
M key, and the digit on the far right of the M-01 display will begin to flash; use ▲ (up) or
▼ (down) to select the memory data set (up and down keys can be held down for
continuous increase or decrease). Press the M key after selected, will stop flash and leave
the function.
5.3 Memory Function
Power ON Press the C button to turn on the wrench. Next, the backlight comes up, and all
the text on the LCD flashes. After displaying 0000 from left to right, the wrench enters into
operation mode.
Turn Off : Press C key and hold 3 seconds to switch off.
Clear : Press C key to reset (when device turned on).

The display generally shows 0%.
In Track mode, assume that the user’s set value is 50Nm. When force applied as the
torque value increase from 0Nm to 25Nm, the screen shows 50%, and so on. When force
decreased, the torque value decreases. When force applied is stopped, the display will
return to the torque setting screen.
The Peak Mode is similar to the Track mode. However, in Peak Mode, the LED light and
the buzzer stops after force applied to the wrench is completely removed.
In Angle mode (Angle series), the two LED light will function as green and red. Assume
that the set angle value is 20°. When the user starts applying force to the wrench, the value
changes from 0°. When the force reaches 80% of the set value, the green LED starts to
flash, and the buzzer starts to sound. When the angle value approaches the set value, the
green LED flashes faster and the buzzer sounds faster.
When the force reaches 100% of the set value, the green LED light up permanently, and the
buzzer sounds continuously. When the force exceeded the set value(101%), the red LED
light up, and the buzzer continues to sound. When force applied stop, the LED lights and the
buzzer stop.
The effects in Peak Mode are similar to what in the Track mode. However, after force
applied is stopped, the display shows the percentage of the last torque value, with the
highest percentage being 100%.
In Angle mode (Angle series), assume that the user’s set value is 50°. When force is
applied such that the angle value increases from 0° to 25°, the screen shows 50%, and so
on. After force applied is stopped, the display shows the percentage of the last angle value,
with the highest percentage being 100%.
