• Be sure to use an AAAalkaline battery for power supply to the transmitter T-FHW.
• Be sure to use a 9V alkaline battery for power supply to the Setting BOX.
• Remove the battery if the product will not be used for a long time.
• Avoid using the instrument in a place where there are metal structures around it.
• Do not install the antenna for the receiver close to any metal pole, electric wire, iron piping, etc.
* Especially, if the antenna and piping are positioned in parallel, the communication status may be
worsened.
• Avoid using the instrument near welding machines, electric discharge machines or machines producing
electromagnetic noise such as PC.
• If the receiver is placed adjacent to the transmitter, different groups must be set between the receiver and
the transmitter.
* If the receiver where the ID is set on a different channel in the same group is placed adjacent to the
transmitter, in extremely rare cases when "simultaneous transmission" occurs, a communication error
may be caused.
• Before wiring, check that the power of the device to be connected to the receiver is in the OFF position.
• Do not handle the torque wrench roughly.
• Do not disassemble or modify.
• Be sure to read the operating instruction of the torque wrench.
• Use a torque wrench within the measurement range specied in the operating instruction.
• Should this instrument give out abnormal smell or catch re during use, stop using it immediately and remove the
AC adapter from the outlet. Then, move the instrument to a safe place and contact Tohnichi Mfg. Co., Ltd.

Radio Frequency Torque Wrench with Double Tightening Detection
5
1. Outline
This remote signal torque wrench allows greater freedom of movement than a wired LS torque wrench.
The receiver can output a signal to Poka Patrol CNA-4mk3 (sold separately) or sends ID data from the
transmitter to PC/PLC via RS232C to establish a missed tightening system.
Furthermore, this product is equipped with a gyro sensor, and it is possible to prevent the bolt from being
tightened twice by monitoring the angle. Torque management is more reliable than Pokayoke, which only
manages the number of tightening times.
2. Feature
• FHSS (Frequency Hopping Spread Spectrum) enhances reliability.
With the application of radio equipment technologies such as Bluetooth, radio signals are received or
transmitted while the frequency is switched at a high speed. If noise or interference with other radio
equipment occurs at a certain frequency, the frequency is automatically switched to make it possible to
receive a high reliable tightening completion signal.
• Simultaneous transmission of 256 transmitters
With this model, adoption of FHSS realizes simultaneous transmission of 256 transmitters.
* Only when 256 receiver groups are set without being overlapped.
A single receiver can control the almost innite number of transmitters.
* Only when simultaneous transmission in the same group does not occur.
About groups and ID
[Group] The 5ch extracted from 78ch frequencies from 2.402GHz to 2.479GHz (1MHz interval) is set as 1 group, and
there are 256 groups in total.
[ID] 000 to 999 and 7 alphanumeric characters can be set. With this ID, the receiver identies the torque wrench.
• Easy transmitter/receiver setting
Without removing the transmitter from the torque wrench or removing the receiver panel, the group and ID
can be set and checked by wireless on the Setting BOX (option).
• Traceability
The serial or reference number of a torque wrench (7-digitalphanumeric characters) can be set as an ID and
transmitted. The tightening bolt (portion) and the manufacturing number (reference number) are managed in
combination, to ensure traceability: "Which torque wrench was used to tighten this bolt (portion)?" → "Which
torque wrench tester was used to calibrate this torque wrench?" → "Which...was used to calibrate this
torque wrench tester?" For 7-digit ID setting, consult to Tohnichi.
• Answer back system
The operator is enable to know the communication status by the LED mounted on the transmitter,
without checking the receiver or the control device.
• 150,000 times of transmittion
An AAA alkaline battery provides 3600 signals per day for 2 months or more.
Battery is easily replaceable by simply sliding the battery cover.
• Equipped gyro sensor detects double tightening
This product uses a gyro sensor to monitor the rotation angle of the torque wrench, and if the tightening angle
did not reach the double tightening judgment angle, wrench judges as NG. The angle can be set on the actual
tightening work or using dedicated setting software and setting box.

Note.
1. Transmitting/receiving distance varies depending on surrounding radio environment.
Radio frequency communication errors may be caused by noise or a shield placed between the transmitter
and the receiver. In addition, radio waves reflected by metal, concrete, etc. may interfere with radio waves
directly sent to the antenna of the receiver and a dead point occurs, resulting in communication error.
2. For the battery life of the transmitter T-FHW, tightening operation can be performed about 150,000 times with a
new alkaline battery. The battery life varies depends on the length of tightening time due to angler detection by
gyro sensor.
3. Refer to each manual for receiver and setting box for details.

6. Precaution for Use
6-1. Caution for correct use
1. Do not handle torque wrench roughly.
2. Read the operating instruction of torque wrench body before use.
3. In order to detect angular rotation from the trigger torque to the nal torque, there is 2 steps of click motion.
The 1st light click feeling occurs when it reaches trigger torque (A position).
The 2nd strong click feeling appears when reached set torque (B position).
Must be tighten by torque wrench until reaching set torque.
4. Refer to setting of Group, judgment code, ID for manual of setting box.

Double Tightening Judgment Function
* About the double tightening judgment function
This product uses a gyro sensor to monitor the rotation angle of the torque wrench, and if the tightening angle
does not reach the double tightening judgment angle, it will be judged as NG. The angle setting can be changed
at setting mode.
The initial setting angle is set at 999 ° for the double tightening judgment angle. Be sure to set it according to
the tightening work. If tightening is performed without setting the double-tightening judgment angle, the double-
tightening judgment will always be NG.
Refer to 7-10 or 8-2 for the setting method.
If you intend to check torque value of body and communication status of the transmitter and receiver at once by
a torque wrench tester, set the angle on zero to shut down the double tightening judgment function.
Item Trigger Torque Double Tightening Judgment Angle
Description Starting torque value for angle measurement. Angle detection starts only while the trigger
torque is exceeded.
Threshold angle for comparison with tightening
angle and double tightening judgment angle.
If the tightening angle is greater than or equal
to the judgment angle, it will be judged as
standard tightening operation, and if it is less
than the judgment angle, judged as double
tightening.
Default 999°
Range 0° to 999°

6-2. Instruction for use
1. Inset a battery then power on the transmitter and
start to angular velocity check and zero adjustment,
so stabilize the wrench during the LED blinks in blue
and red alternately.
2. If it passed the check, LED blinks twice and turns off.
If shock or vibration are given during angle checking,
the LED keeps flashing in red. In above case, on/
off the power by remove and insert the battery and
stabilize the wrench quickly.

3. When the rotated angle at the set torque beyond double tightening judgment angle, transmitter sends
a tightening completion signal to receiver.
In case the angle is less than judgment angle and double tightening NG signal is OFF, transmitter does not
emit signal and if it set at ON, send a 3-digits ID signal for NG.
Refer to 8-2. Setting procedure of setting software.

In this case, wrench does not send signal
once set at double tightening signal OFF.
Conduct correct tightening or reduce the
setting angle to release this error.
Insert and remove the battery to reboot the
transmitter and immediately stand still it.
It can be used once the error is released.
If not, the gyro sensor may have problem,
ask to repair.
Defection of micro switch or tightening is
