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 infinite 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 identifies 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.
